Neuroendocrine Tumor of Ampulla of Vater: A Rare Case Report and Review of Literature
Background
Ampulla of Vater is an extremely rare site for neuroendocrine tumors (NET), accounting for less than 0.3% of gastrointestinal (GI) and 2% of ampullary malignancies. This case report highlights the circuitous diagnosis of this rare tumor in a patient with a history of primary biliary cholangitis presenting with epigastric pain and severe pruritis.
Case Presentation
A 58-year-old female with history of sarcoidosis and primary biliary cholangitis status post sphincterotomy eight months prior, presented with worsening epigastric pain, fatigue, and weight loss over 6 months. Physical exam showed right upper quadrant tenderness. Labs revealed elevated alanine and aspartate aminotransferases at 415 and 195 units/L, with bilirubin of 0.3 mg/dl. Computerized tomography (CT) revealed a 2.3x3.2x4.0 cm peripancreatic hypodensity associated with phlegmon, pancreatic ductal dilation and pneumobilia. Magnetic resonance imaging (MRI) demonstrated a pancreatic head mass. Positron emission tomogram (PET) was negative for distant metastases. After discussion of management options, patient opted for Whipple procedure. The surgical pathology was consistent with invasive ampullary ductal carcinoma of the small intestine, pancreaticobiliary type. However, staining for synaptophysin and chromogranin were positive, with Ki-67 < 55%. Tumor board review confirmed neuroendocrine tumor of the ampulla of Vater. NCCN guidelines recommended active surveillance due to locoregional disease without positive margins or lymph nodes, advising routine follow-up and imaging.
Discussion
Neuroendocrine tumors (NET) at the Ampulla of Vater are exceedingly rare. Often manifesting as obstructive jaundice, they pose diagnostic hurdles, especially in patients with anatomical variations like scarring from primary biliary cholangitis. In a case series of 20 ampullary tumors, only one was neuroendocrine, highlighting their rarity. Accurate diagnosis, achieved through surgical biopsy and immunohistochemical testing, is crucial for appropriate management. Following NCCN guidelines for gastrointestinal NETs, our patient avoided unnecessary systemic treatment meant for adenocarcinoma, preserving her quality of life. Reporting such cases is essential for advancing understanding and refining patient care.
Conclusions
This case had evolving diagnoses, altering both the prognosis and treatment standards. Comorbid primary biliary cholangitis and high-grade tumor complexity posed diagnostic challenges, which was finally confirmed by surgical biopsy. Reporting such cases is vital in aiding tumor management and patient outcomes.

Preleukemic Chronic Myeloid Leukemia: A Case Report and Literature Review
Background
CML is usually classified in chronic phase (CP), accelerated phase (AP) and/or Blast phase (BP). Studies have described another provisional entity as Preleukemic phase of CML which precedes CP and is without leukocytosis and blood features of CP phase of CML. Here we will present a case of metastatic prostate cancer, where next-generation sequencing showed BCR-ABL1 but no overt leukocytosis and then later developed clinical CML after 11 months.
Case Presentation
Our patient was 87-yr-old male with history of metastatic prostate cancer, who presented with elevated PSA levels and new bony metastasis. He underwent next-generation-sequencing (foundation one liquid cdx) in April 2022. It did not show reportable alterations related to prostate cancer but BCR-ABL1 (p210) fusion was detected. It also showed ASXL1-S846fs5 and TET2-Q1548 that are also markers of clonal hematopoiesis. In March 2023 (11 months after the finding of BCR-ABL1), he developed asymptomatic leukocytosis, Workup showed BCR-ABL1(210) of 44% in peripheral blood and bone marrow showed 9% blasts. He was started on Imatinib after shared decision-making and considering the toxicity profile and comorbidities. He followed up regularly with improvement in leukocytosis.
Discussion
The diagnosis of CML is first suspected by typical findings in blood and/or bone marrow and then confirmed by presence of Philadelphia chromosome. Along with chronic and accelerated phases, there is another term described in few cases called “preleukemic or smoldering or aleukemic phase.” This is not a wellestablished term but mostly defined as normal leukocyte count with presence of BCR/ABL1 fusion gene/ ph chromosome. Preleukemic phase of CML is mostly underdiagnosed or misdiagnosed. Our case is unique in that BCR/ABL1 fusion was detected incidentally on next-generation sequencing and patient progressed to chronic phase of CML 11 months later. Upon literature review, few case reports and case series documenting aleukemic/preleukemic phase of CML but timing from the appearance of BCR/ABL1 mutation to actual development to leukocytosis is not well documented. Especially in the era of NGS testing, patients with incidental BCR-ABL1 should be evaluated further irrespective of normal WBC. Further studies need to be done to recognize this early and decrease the delay in treatment.

Male Patient With a History of Monoclonal B Cell Lymphocytosis Presenting with Breast Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma: A Case Report and Literature Review
Background
Monoclonal B cell lymphocytosis (MBL) is defined as presence of clonal b cell population that is fewer than 5 × 10(9)/L B-cells in peripheral blood and no other signs of a lymphoproliferative disorder. Patients with MBL are usually monitored with periodic history, physical exam and blood counts. Here we presented a case of chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) in breast in a patient with a history of MBL.
Case Presentation
68-year-old male with history of MBL underwent mammogram for breast mass. It showed suspicious 4.4 x 1.6 cm solid and cystic lesion containing a 1.7 x 0.9 x 1.8 cm solid hypervascular mass. Patient underwent left breast mass excision. Histologic sections focus of ADH involving papilloma with uninvolved margins. Lymphoid infiltrates noted had CLL/SLL immunophenotype and that it consists mostly of small B cells positive for CD5, CD20, CD23, CD43, Bcl-2, LEF1. CT CAP and PET/CT were negative for lymphadenopathy. Bone marrow biopsy showed marrow involvement by mature B-cell lymphoproliferative process, immunophenotypically consistent with CLL/SLL. As intra-ductal papilloma completely excised and hemogram was normal tumor board recommended surveillance only for CLL/SLL.
Discussion
MBL can progress to CLL, but it can rarely be presented as an extra-nodal mass in solid organs. We described a case of MBL that progressed to CLL/ SLL in breast mass in a male patient. This is the first reported case in literature where MBL progressed to CLL/ SLL of breast without lymphadenopathy. Upon literature review 8 case reports were found where CLL/SLL were described in breast tissue. 7 of them were in females and 1 one was in male. Two patients had CLL before breast mass but none of them had a history of MBL. 3 described cases in females had CLL/SLL infiltration of breast along with invasive ductal carcinoma. So, a patient with MBL can progress to involve solid organs despite no absolute lymphocytosis and should be considered in differentials of a new mass. Although more common in females, but it can occur in males as well. It’s important to consider the possibility of both CLL/SLL and breast cancer existing simultaneously.

Chronic Myeloid Leukemia Presenting as Priapism: A Rare and Acute Initial Presentation in a Young Male
Introduction
Priapism, defined as a prolonged and often painful penile erection without sexual arousal, constitutes a urological emergency requiring immediate intervention. While commonly associated with conditions like sickle cell anemia and certain medications, malignancy-related priapism is rare and frequently overlooked. Herein, we present a unique case of a 31-year-old male with no significant medical history, who developed persistent priapism as the initial presentation of chronic myeloid leukemia (CML).
Case Presentation
A 31-year-old male without significant medical history, presented to the emergency department with painless priapism, was evaluated by urology and discharged home with precautions. He returned the following day with persistent, now painful priapism. Upon examination, his vital signs were stable. Urology performed aspiration and injection with Sudafed, resulting in mild symptom improvement. Laboratory findings revealed elevated white blood cell count (563.64 k/mcL), anemia (hemoglobin 8.4 g/dL), and a peripheral blood smear showed immature circulating cells with blast forms. He was transferred to a tertiary care center where conservative management addressed bleeding from the penile injection site, with subsequent treatment including leukapheresis and hydroxyurea for cytoreduction. Imaging revealed severe splenomegaly (36 cm) with abdominal mass effect. Peripheral flow cytometry didn’t show malignancy, but cytogenetic analysis showed a BCR/ABL1 fusion gene, confirming chronic myeloid leukemia (CML). Bone marrow biopsy showed hypercellularity without increased blasts. Treatment with dasatinib reduced the white count to 52,000 k/mcL, and was discharged home.
Discussion
Priapism is a urological emergency necessitating immediate intervention to prevent erectile dysfunction and permanent impotence. Management aims to achieve detumescence and typically involves methods such as irrigation or injection of vasoconstrictors into the penis. Malignancy-associated priapism (MAP) often results from venous obstruction due to hyperviscosity. Studies show that CML accounts for approximately 50% cases presenting with MAP, predominantly affecting younger individuals with a mean onset around 27 years of age. Priapism can occur before, during, or after treatment initiation or splenectomy in these patients. Providers should keep a high threshold of suspicion for MAP in patients with no other risk factors as prompt identification and treatment are needed to avoid permanent injury.

UC as a Culprit for Hemolytic Anemia
Introduction
Autoimmune hemolytic anemia (AIHA) can rarely be seen as an extra-intestinal manifestation (EIM) of inflammatory bowel disease (IBD), mostly ulcerative colitis (UC). This case report describes the clinical significance of recognizing AIHA in the context of UC.
Case Presentation
A 32-year-old male presented with profound fatigue, pallor, and dyspnea on exertion for one month. He also recalled intermittent bloody diarrhea for two years for which he never sought medical attention. Physical examination was unremarkable except for mid-abdominal tenderness. Labs revealed microcytosis, hemoglobin of 3.8 g/dL, total bilirubin 2.9 mg/ dL, indirect bilirubin of 2.0 mg/dL, LDH 132 U/L alk-p 459 U/L AST 98 U/L ALT 22 U/L. Direct Coombs test was positive suggesting warm AIHA with pan-agglutinin positive on the eluate test. Further testing revealed negative hepatitis and HIV panels and positive fecal calprotectin. CT abdomen and pelvis showed ascites, right pleural effusion and hepatosplenomegaly. Colonoscopy confirmed the diagnosis of ulcerative colitis, with extensive involvement of the colon. Mesalamine was initiated. Hematology was consulted for AIHA, who started the patient on methylprednisone leading to resolution of hemolytic anemia and improvement in gastrointestinal symptoms.
Discussion
IBD typically manifests as colitis, and the incidence of EIM as an initial symptom is observed in less than 10% cases. However, over the course of their lifetime, approximately 25% of patients will experience EIM, underscoring their relevance to clinical outcomes. Anemia is very common in IBD patients, mostly iron deficiency anemia (IDA) or anemia of chronic disease (ACD). However, AIHA can represent a rare but significant EIM of ulcerative colitis (UC), often posing diagnostic challenges. The underlying pathophysiological mechanisms linking UC and AIHA remain incompletely understood, necessitating a multidisciplinary approach to management. Treatment strategies focus on controlling both the hemolysis and the underlying IBD, emphasizing the importance of tailored interventions.
Conclusion
This case underscores the clinical significance of AIHA as an EIM of ulcerative colitis (UC), particularly when presenting as the primary symptom. Timely recognition is paramount to optimizing patient outcomes and preventing disease progression. Further research is warranted to elucidate the underlying mechanisms and therapeutic strategies for AIHA in the context of UC.

IBD typically manifests as colitis, and the incidence of EIM as an initial symptom is observed in less than 10% cases. However, over the course of their lifetime, approximately 25% of patients will experience EIM, underscoring their relevance to clinical outcomes. Anemia is very common in IBD patients, mostly iron deficiency anemia (IDA) or anemia of chronic disease (ACD). However, AIHA can represent a rare but significant EIM of ulcerative colitis (UC), often posing diagnostic challenges. The underlying pathophysiological mechanisms linking UC and AIHA remain incompletely understood, necessitating a multidisciplinary approach to management. Treatment strategies focus on controlling both the hemolysis and the underlying IBD, emphasizing the importance of tailored interventions.
Conclusion
This case underscores the clinical significance of AIHA as an EIM of ulcerative colitis (UC), particularly when presenting as the primary symptom. Timely recognition is paramount to optimizing patient outcomes and preventing disease progression. Further research is warranted to elucidate the underlying mechanisms and therapeutic strategies for AIHA in the context of UC.
The First Patient in the Veteran Affairs System to Receive Chimeric Antigen Receptors T-cell Therapy for Refractory Multiple Myeloma and the Role of Intravenous Immunoglobulin in the Prevention of Therapy-associated Infections
Background
In 3/2021, chimeric antigen receptor (CAR) T-cell therapy was approved for the treatment of multiple myeloma in adult patients with refractory disease. Currently, only the Veterans Affair (VA) center at the Tennessee Valley Healthcare System (TVHS) offers this treatment. Herein, we report a significant healthcare milestone in 2024 when the first patient received CAR T-cell therapy for multiple myeloma in the VA system. Additionally, the rate of hypogammaglobulinemia is the highest for CAR T-cell therapy using idecabtagene vicleucel compared to therapies using other antineoplastic agents (Wat et al, 2021). The complications of hypogammaglobulinemia can be mitigated by intravenous immunoglobulin (IVIG) treatment.
Case Presentation
A 75-year-old male veteran was diagnosed with IgA Kappa multiple myeloma and received induction therapy with bortezomib, lenalidomide, and dexamethasone in 2014. The patient underwent autologous stem cell transplant (SCT) in the same year. His disease recurred in 3/2019, and the patient was started on daratumumab and pomalidomide. He received another autologous SCT in 2/2021, to which he was refractory. The veteran then received treatment with daratumumab and ixazomib, followed by carfilzomib and cyclophosphamide. Starting in 9/2022, the patient also required regular IVIG treatment for hypogammaglobulinemia. He eventually received CAR T-cell therapy with idecabtagene vicleucel at THVS on 4/18/2024. The patient tolerated the treatment well and is undergoing routine disease monitoring. Following CAR T-cell therapy, his hypogammaglobulinemia persists with immunoglobulins level less than 500 mg/dL, and the veteran is still receiving supportive care IVIG.
Discussion
A population estimate of 1.3 million veterans are uninsured and can only access healthcare through the VA (Nelson et al, 2007). This case highlights the first patient to receive CAR T-cell therapy for multiple myeloma in the VA system, indicating that veterans now have access to this life-saving treatment. The rate of hypogammaglobulinemia following CAR T-cell therapy for multiple myeloma is as high as 41%, with an associated infection risk of 70%. Following CAR T-cell therapy with idecabtagene vicleucel, around 61% of patients will require IVIG treatment (Wat el al, 2021). Our case adds to this growing literature on the prevalence of IVIG treatment following CAR T-cell therapy in this patient population.

The First Female Patient in the Veteran Affairs System to Receive Chimeric Antigen Receptors (CAR) T-cell Therapy for Refractory Multiple Myeloma and the Role of CAR T-cell Therapy in Penta-refractory Disease
Background
In 2024, the first two veterans, both from the Michael E. DeBakey Veteran Affairs (VA) Medical Center, received chimeric antigen receptors (CAR) T-cell therapy for refractory multiple myeloma through the Tennessee Valley Healthcare System (TVHS). Currently, TVHS is the only VA where this treatment is available. One of these patients also had penta-refractory multiple myeloma (P-RMM), which is associated with significantly worse progression-free survival and overall survival (OS) (Gill et al, 2021). P-RMM is defined as resistance to at least two immunomodulatory drugs, two different proteasome inhibitors, and one CD38 monoclonal antibody.
Case Presentation
A 71-year-old female veteran was diagnosed with high-risk multiple myeloma and received induction therapy with carfilzomib, lenalidomide, and dexamethasone in 2017. She underwent autologous stem cell transplant (SCT) in 4/2018. The veteran subsequently received maintenance therapy with lenalidomide, bortezomib, and dexamethasone. Her disease recurred in 1/2022. The patient then received two more lines of treatments with daratumumab and pomalidomide followed by selinexor. She had another autologous SCT in 5/2023, to which she was refractory. Her fifth line therapy included addition of bortezomib to her selinexor regimen. She eventually underwent CAR T-cell therapy at THVS on 5/1/2024 with good tolerance of therapy. At her follow-up visit, the patient had significant response to CAR T-cell treatment, based on her symptoms and improvement in free light chains and serum protein electrophoresis.
Discussion
CAR T-cell therapy is one of the newest and most cutting-edge therapies for patients with refractory multiple myeloma. Access to this therapy has been limited throughout the country. However, as shown by our case, this life-saving treatment is now available to patients within the VA. According to a retrospective study on P-RMM patients, the OS in patients who received B-cell maturation antigen (BCMA) targeted therapy was significantly higher than in those who did not (17 vs. 6 months, p < 0.0001). Among the BCMA-targeted therapies, CAR T-cell therapy is associated with the highest OS (29 months) compared to antibody-drug conjugates and bispecific T-cell engagers (Atrash et al, 2023). Thus, accessibility to CAR T-cell therapy was essential in our patient with P-RMM in ensuring her best survival outcomes.

A Clonal Complete Remission Induced by IDH1 Inhibitor Ivosidenib in a Myelodysplastic Syndrome (MDS) With Co-Mutations of IDH1 and the ZRSR2 RNA Splicing Gene
Background
IDH1 mutations are detected in 3-4% of MDS, nearly always with one or more co-mutations. Treatment with IDH1 inhibitor ivosidenib typically resulted in regression of the abnormal clone in 15 reported responders. However, in a few cases differentiation was restored from the abnormal clone. Here we report a durable MDS remission despite sustained proliferation of a clone with IDH1 and ZRSR2 mutations.
Case Presentation
A 49-year-old man developed severe neutropenia and macrocytic anemia in January 2019. Mild marrow dysplasia developed by March 2020 with IDH1 (31.1%) and splicing gene ZRSR2 (55.7%) mutations. In October 2022 biopsy showed MDS with 4% blasts, megakaryocytic/granulocytic hypoplasia, normal cytogenetics and 43% IDH1/89% ZRSR2. After azacytidine failure, ivosidenib was started in November 2023 following FDA approval. Within weeks ANCs increased from 170 to 1580 and hemoglobin from 7.9 to 11.6 with MCV 115, reticulocytes 1.72%. At 3 months a CBC was normal except for MCV 111. IDH1 and ZRSR2 were 36.4% and 71%. After 6 months, ANC was 2380, hemoglobin 14.7, MCV 108.6, reticulo-cytes 1.77%. IDH1 PCR showed a 33.1% allele frequency consistent with a clonal remission.
Discussion
IDH1 mutations in MDS/AML frequently co-occur with mutations in RNA splicing genes SRSF2 or ZRSR2. For ZRSR2, we previously reported that isolated mutations of this gene cause refractory macrocytic anemias without dysplasia, thus presenting as clonal cytopenias of undetermined significance (Fleischman et al., Leuk Res, 2017). In this MDS case, after ivosidenib treatment the ZRSR2 splicing defect sustained clonal dominance over polyclonal hematopoiesis while accounting for macrocytosis. Longitudinal data for two ivosidenib-treated IDH1/SRSF2 MDS cases are incomplete, but one case of IDH2/SRSF2 MDS treated with the inhibitor enasidenib similarly achieved complete remission without regression of the mutated clone for 12 months.
Conclusions
Following the FDA approval of ivosidenib, all cases of MDS should have DNA sequencing performed at diagnosis to identify IDH1 mutations. Treatment induces high rates of remission even when polyclonal hematopoiesis does not recover. Moreover, the restoration of hematopoietic differentiation by the abnormal clone provides unique insights into the clinical phenotype and fitness advantage conferred by the co-existing driver mutations.

Asynchronous Bilateral Breast Cancer in a Male Patient
Background
Bilateral male breast cancer remains a rare occurrence with limited representation in published literature. Here we present a case of an 82-yearold male with asynchronous bilateral breast cancer.
Case Presentation
Our patient is an 82-year-old male past smoker initially diagnosed with left T1aN0M0 invasive lobular carcinoma in 2010 that was ER, PR positive and HER2 negative. He underwent a left mastectomy with sentinel node biopsy and was given tamoxifen therapy for 10 years. In 2020, the patient was also diagnosed with lung squamous cell carcinoma and was treated with stereotactic body radiotherapy. In September 2023, he started noticing discharge from his right nipple. A PET CT scan revealed hyper-metabolic activity in the bilateral upper lung lobes and slightly increased activity in the right breast. A biopsy of the left upper lobe showed atypical cells. He also underwent a right breast mastectomy and sentinel lymph node biopsy which showed grade 1-2 ductal carcinoma in situ and negative sentinel lymph nodes. The tumor board recommended no further treatment after his mastectomy and genetic testing which is currently pending.
Discussion
Male breast cancer comprises just 1% of breast cancer cases, with asynchronous bilateral occurrences being exceedingly rare. A review of PubMed literature yielded only 2 documented case reports. Male breast cancer usually diagnosed around ages 60 to 70 years. The predominant histopathological diagnosis is invasive ductal adenocarcinoma that more frequently expresses ER/PR over HER2. It often manifests as a painless lump, frequently diagnosed at an advanced stage, possibly due to factors such as lower screening rates in males and less breast parenchyma. Local treatment options include surgery and radiotherapy. Neoadjuvant tamoxifen therapy is appropriate for ER and PR expressing cancers and chemotherapy can be used for non-hormone expressing or metastatic tumors. Given its rarity, management and diagnostic strategies for male breast cancer are often adapted from research on female breast cancer
Conclusions
Our case is of a relatively uncommon incident of asynchronous bilateral male breast cancer, emphasizing the need for expanded research efforts in male breast cancer. An enhanced understanding could lead to improved diagnosis and management strategies, potentially enhancing survival outcomes.

Metastatic Prostate Cancer Presenting as Pleural and Pericardial Metastases: A Case Report and Literature Review
Background
Metastatic prostate cancer typically manifests with metastases to the lungs, bones, and adrenal glands. Here, we report a unique case where the initial presentation involved pleural nodules, subsequently leading to the discovery of pleural and pericardial metastases.
Case Presentation
Our patient, a 73-year-old male with a history of active tobacco use disorder, COPD, and right shoulder melanoma (2004), initially presented to his primary care physician for a routine visit. Following a Low Dose Chest CT scan (LDCT), numerous new pleural nodules were identified. Physical examination revealed small nevi and skin tags, but no malignant characteristics. Initial concerns centered on the potential recurrence of malignant melanoma with pleural metastases or an inflammatory condition. Subsequent PET scan results raised significant suspicion of malignancy. PSA was 2.41. Pleuroscopy biopsies revealed invasive nonsmall cell carcinoma, positive for NKX31 and MOC31, but negative for S100, PSA, and synaptophysin. This pattern strongly suggests metastatic prostate cancer despite the absence of PSA staining. (Stage IV B: cTxcN1cM1c). A subsequent PSMA PET highlighted extensive metastatic involvement in the pericardium, posterior and mediastinal pleura, mediastinum, and ribs. Treatment commenced with Degarelix followed by the standard regimen of Docetaxel, Abiraterone, and prednisone. Genetic counseling and palliative care services were additionally recommended.
Discussion
Prostate cancer typically spreads to bones, lungs, liver, and adrenal glands. Rarely, it appears in sites like pericardium and pleura. Pleural metastases are usually found postmortem; clinical diagnosis is rare. Pericardial metastases are exceptionally uncommon, with few documented cases. The precise mechanism of metastatic dissemination remains uncertain, with theories suggesting spread through the vertebral-venous plexus or via the vena cava to distant organs. Treatment approaches vary based on symptomatic effusions, ranging from pericardiocentesis, thoracocentesis to chemotherapy, radiotherapy, and hormone therapy. Studies have shown systemic docetaxel to be effective in managing pleural and pericardial symptoms. Despite their rarity, healthcare providers should consider these possibilities when encountering pleural thickening or pericardial abnormalities on imaging studies.
Conclusions
Pleural and pericardial metastases represent uncommon occurrences in prostate cancer. Continued research efforts can facilitate early detection of metastatic disease, enabling more effective and precisely targeted management strategies when symptoms manifest.

Initial concerns centered on the potential recurrence of malignant melanoma with pleural metastases or an inflammatory condition. Subsequent PET scan results raised significant suspicion of malignancy. PSA was 2.41. Pleuroscopy biopsies revealed invasive nonsmall cell carcinoma, positive for NKX31 and MOC31, but negative for S100, PSA, and synaptophysin. This pattern strongly suggests metastatic prostate cancer despite the absence of PSA staining. (Stage IV B: cTxcN1cM1c). A subsequent PSMA PET highlighted extensive metastatic involvement in the pericardium, posterior and mediastinal pleura, mediastinum, and ribs. Treatment commenced with Degarelix followed by the standard regimen of Docetaxel, Abiraterone, and prednisone. Genetic counseling and palliative care services were additionally recommended.
Discussion
Prostate cancer typically spreads to bones, lungs, liver, and adrenal glands. Rarely, it appears in sites like pericardium and pleura. Pleural metastases are usually found postmortem; clinical diagnosis is rare. Pericardial metastases are exceptionally uncommon, with few documented cases. The precise mechanism of metastatic dissemination remains uncertain, with theories suggesting spread through the vertebral-venous plexus or via the vena cava to distant organs. Treatment approaches vary based on symptomatic effusions, ranging from pericardiocentesis, thoracocentesis to chemotherapy, radiotherapy, and hormone therapy. Studies have shown systemic docetaxel to be effective in managing pleural and pericardial symptoms. Despite their rarity, healthcare providers should consider these possibilities when encountering pleural thickening or pericardial abnormalities on imaging studies.
Conclusions
Pleural and pericardial metastases represent uncommon occurrences in prostate cancer. Continued research efforts can facilitate early detection of metastatic disease, enabling more effective and precisely targeted management strategies when symptoms manifest.
Background
Metastatic prostate cancer typically manifests with metastases to the lungs, bones, and adrenal glands. Here, we report a unique case where the initial presentation involved pleural nodules, subsequently leading to the discovery of pleural and pericardial metastases.
