The Diagnosis: Aneurysmal Dermatofibroma

A shave biopsy of the entire tumor was performed at the initial visit. Histologic examination with hematoxylin and eosin staining revealed a fibrohistiocytic infiltrate containing cleftlike cavernous spaces lined by epithelial cells (Figure, A). Immunohistochemical staining revealed factor XIIIa expression on fibrohistiocytic cells (Figure, B). CD34 was expressed on vascular endothelial cells, but it failed to highlight the fibrohistiocytic space (Figure, C). Overall, these findings supported the diagnosis of aneurysmal dermatofibroma. The lesion healed without complications, and the patient was counseled on the risk for recurrence. He was offered localized excision but opted for conservative management without excision and close follow-up and monitoring.

Dermatofibromas are common benign cutaneous nodules that often are asymptomatic and occur on the extremities. Dermatofibromas also are known as cutaneous fibrous histiocytomas and have numerous histologic variants. Aneurysmal dermatofibroma (also called aneurysmal fibrous histiocytoma) is a rare histologic variant of dermatofibroma presenting as a slow-growing exophytic tumor that can be purple, red, brown, or blue. Although classic dermatofibromas typically constitute a straightforward diagnosis, aneurysmal dermatofibromas often are more challenging to clinically differentiate from other cutaneous neoplasms. Additionally, due to the exophytic nature and larger size (0.5–4.0 cm), aneurysmal dermatofibromas do not exhibit the characteristic dimple (Fitzpatrick) sign found in many dermatofibromas. Aneurysmal dermatofibromas are 10 times more likely to recur than classic dermatofibromas.^1-4

Aneurysmal dermatofibromas can mimic other cutaneous neoplasms, some indolent and others more aggressive. Similar to aneurysmal dermatofibromas, solitary neurofibromas and nevi lipomatosus can appear as asymptomatic exophytic nodules with a similar spectrum of color and indolent clinical courses. In nevus lipomatosus, the dermis is almost entirely replaced by mature adipose tissue.⁵ Solitary neurofibromas represent a proliferation of neuromesenchymal cells with haphazardly arranged, wavy nuclei characteristic of nerve cells.⁶ Dermatofibrosarcoma protuberans can be distinguished from aneurysmal dermatofibroma by lack of factor XIIIa expression and diffuse positivity for CD34.⁷ Finally, aneurysmal dermatofibromas may resemble vascular tumors such as nodular Kaposi sarcoma. Kaposi sarcoma can be differentiated from an aneurysmal dermatofibroma by the presence of characteristic vascular wrapping, the absence of fibrohistiocytic cells, and expression of human herpesvirus 8 latent nuclear antigen-1.^1,8 Although aneurysmal dermatofibromas are of low malignant potential, they are associated with a higher rate of recurrence compared to common dermatofibromas.⁹ Definitive treatment involves complete excision with follow-up to ensure no signs of recurrence.¹⁰ Incomplete excision can increase the likelihood of recurrence, especially for larger aneurysmal dermatofibromas. Aneurysmal dermatofibromas are one of the subtypes of dermatofibromas that may extend into the subcutaneous tissue. Han et al² found that 77.8% of aneurysmal dermatofibromas extended into subcutaneous tissue. Recognizing the clinical and pathological features of this rare subtype of dermatofibroma can aid dermatologists in appropriate recognition and management.

Recently,  the results of a survey of consumers regarding their health care experiences were reported by Carta Healthcare. As you might expect, a top complaint about doctors was time spent waiting to see them; 23% said they waited 30 minutes or longer. I’ve written about punctuality before, but this is such a ubiquitous problem that it bears repeating. Here are some suggestions:

Start on time. That seems obvious, but I’m always amazed at the number of doctors who admit to running late who also admit that they start late. If you’re in the hole before you even start, you can seldom dig yourself out. Sometimes an on-time start is the solution to the entire problem! If you doubt me, try it.

Book realistically. Everyone works at a different pace. Determine the number of patients you can comfortably see in an hour, and book only that number. If you want to see more patients, the solution is working longer hours or hiring physicians or physician extenders (or both), not overloading your schedule.

Time-stamp each chart. Pay attention to patient arrival times if your EHR records them, and step up your pace if you start to fall behind. If your EHR does not record arrival times or you are still using paper records, buy a time clock and have your receptionist time-stamp the “encounter form” that goes to the back with the patient. One glance at the stamp will tell you exactly how long that patient has been waiting.

Schedule all surgeries. If you haven’t scheduled the time necessary for a surgical procedure, don’t do it. It’s frequently tempting to “squeeze in” an excision, often because you feel guilty that the patient has already had to wait for you. But every unscheduled surgery puts you that much further behind. And hurrying through a procedure increases the risk of mistakes. Tell the patient that surgery requires extra time and it can’t be rushed, so you will have to schedule that time.

Work-ins come last, not first. Patients with urgent problems should be seen after scheduled patients. That may seem counterintuitive; receptionists often assume it’s better to squeeze them in early, while you’re still running on time. But doing that guarantees you will run late, and it isn’t fair to patients who have appointments and expect to be seen promptly.

Work-ins, on the other hand, expect a wait because they have no appointment. We tell them, “Our schedule is full today; but if you come at the end of hours, the doctor will see you. But you may have a wait.” Far from complaining, they invariably thank us for seeing them.

Seize the list. You know the list I mean. “Number 16: My right big toe itches. Number 17: I think I feel something on my back. Number 18: This weird chartreuse thing on my arm ...” One long list can leave an entire half-day schedule in shambles.

When a list is produced, the best option is to take it and read it yourself. Identify the most important two or three problems, and address them. For the rest, I will say, “This group of problems deserves a visit of its own, and we will schedule that visit.”

Ask if you can place the list (or a photocopy) in the patient’s chart. (It is, after all, important clinical information.) All of these problems are important to the patient and should be addressed – but on your schedule, not the patient’s.

Avoid interruptions. Especially phone calls. Unless it’s an emergency or an immediate family member, my receptionists say, “I’m sorry, the doctor is with patients. May I take a message?” Everyone – even other physicians – understands. But be sure to return those calls promptly.

Pharmaceutical reps should not be allowed to interrupt you, either. Have them make an appointment, just like everybody else.

There will be times, of course, when you run late. But these should be the exception rather than the rule. By streamlining your procedures and avoiding the pitfalls mentioned, you can give nearly every patient all the time he or she deserves without keeping the next patient waiting.

Incidentally, other common patient complaints in that survey were the following:

• Couldn’t schedule an appointment within a week.
• Spent too little time with me.
• Didn’t provide test results promptly.
• Didn’t respond to my phone calls promptly.

Now would be an excellent opportunity to identify and address any of those problems as well.

This linear pattern of hyper-pigmented, often verrucous tissue oriented along Blaschko skin lines is typical for linear epidermal nevi (LEN). In some cases, lesions are not in a linear pattern and are actually in more of a localized or whorled pattern (called epidermal nevi).

LEN are usually present at birth, as in this individual. They are frequently seen on the head and neck region and are often asymptomatic. LEN are considered a birthmark that develops because of a genetic abnormality that typically affects keratinocytes. This genetic mutation only affects a portion of the body (mosaicism) without affecting the overall genetics of the individual. This is important to note because LEN do not typically have a hereditary component or implications for offspring. While usually asymptomatic and localized, LEN can be associated with extracutaneous and neurologic difficulties. In these situations, it is called epidermal nevus syndrome, and is more common if the LEN occur on the face or head.¹

Since LEN are usually asymptomatic, treatment is not required unless the lesions affect the function of adjacent structures, such as the eyes, lips, or nose. Due to their frequent presence on the face or other visible areas, some patients may choose to get these lesions treated for cosmetic purposes. In the past, full-thickness excision was recommended. Topical medications are ineffective, and superficial shave excision usually leads to recurrence. More recently, destructive laser treatments have been used, with success, to reduce the appearance of the lesions.²

This patient was not concerned about the appearance of the asymptomatic lesions and chose not to have any treatment.

Type 2 diabetes (T2D) is a chronic, progressive disease marked by ongoing decline in insulin sensitivity and beta-cell function over time. Clinical trials have shown that lowering A1C to ∼7.0% (53 mmol/mol), especially after an early diagnosis, can markedly reduce the long-term complications of T2D. Metformin has become the generally recommended first therapeutic agent in treating T2D due to the drug’s long-term experience, effectiveness, and avoidance of hypoglycemia or weight gain. However, it is clear that additional agents are necessary to regain glucose control when metformin eventually fails due to the progressive nature of the disease.

Insufficient data on comparative efficacy and durability of effect has led to uncertainty in recommendations for the preferred second agent. Comparative effectiveness has been reported primarily in industry-sponsored trials of relatively short duration. With this in mind, the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) sponsored the Glycemia Reduction Approaches in Diabetes: A Comparative Effectiveness (GRADE) Study. This landmark, randomized controlled study was initiated in 2013, enrolling patients on metformin alone within 10 years of diagnosis of T2D. It involved 36 research sites in the United States with a mean follow-up of 5 years. The participants were randomized to adding a dipeptidyl peptidase 4 (DPP-4) inhibitor (sitagliptin), a sulfonylurea (glimepiride), basal insulin (glargine), or a glucagon-like peptide 1 receptor agonist (GLP-1 RA) (liraglutide), with the primary outcome being time to A1C over 7.0%.

The GRADE study was unique in several ways: its size, scope, length, and the fact that the financial support and design planning stemmed from a U34 planning grant from the NIDDK. The study population of 5047 participants was very diverse, reflecting the population affected by T2D. A mix of racial and ethnic groups were represented, including 19.8% Black participants and 18.6% Hispanic participants. It is unlikely that a similar comparative effectiveness trial of pharmacologic treatment of T2D will be performed again in the future, considering the high costs and length of time required for such a study amid the dynamic drug development environment today. In fact, the final implementation of study results is somewhat complicated by the subsequent approval of GLP-1 RAs of greater efficacy, weight loss, and convenience, as well as sodium-glucose cotransporter 2 (SGLT2) inhibitors and, most recently, a dual GLP-1/gastric inhibitory polypeptide (GIP) receptor agonist (tirzepatide). Many of these newer agents have demonstrated nonglycemic benefits, such as reduced risk of cardiovascular (CV) events or reduced progression of renal disease. The findings from the GRADE study, however, did provide important insight on the long-term management of T2D.

The GRADE study was the first to compare the efficacy of 4 US Food and Drug Administration–approved drugs for T2D in maintaining blood glucose levels for the longest amount of time in patients with T2D. It also monitored microvascular complications, CV events, and adverse drug effects.

An important message of the study that may be overlooked is that all of the studied agents’ ability to maintain an A1C under 7.0% was quite low—as 71% of all participants reached the primary outcome by 5 years; the best results for a group were 67% for glargine and 68% for liraglutide. In general, the results showed that liraglutide and insulin glargine were superior to glimepiride and sitagliptin in controlling blood sugars. They provided approximately 6 months’ more time with blood glucose levels in the desired range compared with sitagliptin, which was shown to provide the least amount of time in maintaining glucose levels. Fifty-five percent of the sitagliptin group experienced the primary outcome at 1 year. Sitagliptin was particularly ineffective for the patient subgroup with an A1C at baseline of 7.8% or higher, where 70% reached the primary outcome in 1 year. The results were uniform regarding age, race, sex, and ethnicity of the trial participants. The intention-to-treat design of the study limits the conclusions about A1C differences, as failure to maintain an A1C under 7.5% required addition of prandial insulin for the glargine group and the addition of glargine to the other 3 groups. Although subjects receiving glargine had an initial glucose-lowering effect that was less than that seen with liraglutide, the ability to keep titrating the glargine likely had an impact on the long-term benefit of that agent. When the glargine group neared or in some cases even passed the secondary outcome A1C level of 7.5%, the basal insulin was increased to lower the A1C, sometimes even when the protocol would recommend adding prandial insulin.  

The study was not powered specifically for determining the relative risk of CV events. However, there was some evidence that liraglutide was associated with lower CV risk than the other 3 agents by about 30%. There was no difference in microvascular risk among the agents in this study of relatively short-term disease. Side effects were not a major problem and no different than expected. Glargine and glimepiride were associated with less weight loss, while liraglutide had a particular benefit on weight. Glimepiride is associated with significantly more frequent incidents of severe hypoglycemia, though the rates of severe hypoglycemia were quite low. Liraglutide users reported significantly higher rates of nausea and had a higher early drop-out rate, but did not show a difference in continued use by the end of the study.  

In summary, the GRADE trial confirmed that glucose control in T2D is a progressive problem, as the addition of all 4 classes of medication failed to keep most patients in the target glucose range. However, basal insulin and GLP-1 RAs outperformed the other 2 classes. Sitagliptin has the poorest metabolic profile. One could argue that, based on overall metabolic control and concomitant weight benefits, less need for glucose monitoring, simple titration, apparent CV benefit, and insignificant hypoglycemia, GLP-1 RAs offer the best option as an agent to add to metformin. This conclusion is fortified by the fact that the agent used to represent this class in the study appears to be less effective in reducing glucose and weight and offers less convenience than the newer, once-weekly GLP-RAs available today.   

Type 2 diabetes (T2D) is a chronic, progressive disease marked by ongoing decline in insulin sensitivity and beta-cell function over time. Clinical trials have shown that lowering A1C to ∼7.0% (53 mmol/mol), especially after an early diagnosis, can markedly reduce the long-term complications of T2D. Metformin has become the generally recommended first therapeutic agent in treating T2D due to the drug’s long-term experience, effectiveness, and avoidance of hypoglycemia or weight gain. However, it is clear that additional agents are necessary to regain glucose control when metformin eventually fails due to the progressive nature of the disease.

The participants were randomized to adding a dipeptidyl peptidase 4 (DPP-4) inhibitor (sitagliptin), a sulfonylurea (glimepiride), basal insulin (glargine), or a glucagon-like peptide 1 receptor agonist (GLP-1 RA) (liraglutide), with the primary outcome being time to A1C over 7.0%.

The GRADE study was unique in several ways: its size, scope, length, and the fact that the financial support and design planning stemmed from a U34 planning grant from the NIDDK. The study population of 5047 participants was very diverse, reflecting the population affected by T2D. A mix of racial and ethnic groups were represented, including 19.8% Black participants and 18.6% Hispanic participants. It is unlikely that a similar comparative effectiveness trial of pharmacologic treatment of T2D will be performed again in the future, considering the high costs and length of time required for such a study amid the dynamic drug development environment today. In fact, the final implementation of study results is somewhat complicated by the subsequent approval of GLP-1 RAs of greater efficacy, weight loss, and convenience, as well as sodium-glucose cotransporter 2 (SGLT2) inhibitors and, most recently, a dual GLP-1/gastric inhibitory polypeptide (GIP) receptor agonist (tirzepatide). Many of these newer agents have demonstrated nonglycemic benefits, such as reduced risk of cardiovascular (CV) events or reduced progression of renal disease. The findings from the GRADE study, however, did provide important insight on the long-term management of T2D.

The GRADE study was the first to compare the efficacy of 4 US Food and Drug Administration–approved drugs for T2D in maintaining blood glucose levels for the longest amount of time in patients with T2D. It also monitored microvascular complications, CV events, and adverse drug effects.

An important message of the study that may be overlooked is that all of the studied agents’ ability to maintain an A1C under 7.0% was quite low—as 71% of all participants reached the primary outcome by 5 years; the best results for a group were 67% for glargine and 68% for liraglutide. In general, the results showed that liraglutide and insulin glargine were superior to glimepiride and sitagliptin in controlling blood sugars. They provided approximately 6 months’ more time with blood glucose levels in the desired range compared with sitagliptin, which was shown to provide the least amount of time in maintaining glucose levels. Fifty-five percent of the sitagliptin group experienced the primary outcome at 1 year. Sitagliptin was particularly ineffective for the patient subgroup with an A1C at baseline of 7.8% or higher, where 70% reached the primary outcome in 1 year. The results were uniform regarding age, race, sex, and ethnicity of the trial participants. The intention-to-treat design of the study limits the conclusions about A1C differences, as failure to maintain an A1C under 7.5% required addition of prandial insulin for the glargine group and the addition of glargine to the other 3 groups. Although subjects receiving glargine had an initial glucose-lowering effect that was less than that seen with liraglutide, the ability to keep titrating the glargine likely had an impact on the long-term benefit of that agent. When the glargine group neared or in some cases even passed the secondary outcome A1C level of 7.5%, the basal insulin was increased to lower the A1C, sometimes even when the protocol would recommend adding prandial insulin.  

The study was not powered specifically for determining the relative risk of CV events. However, there was some evidence that liraglutide was associated with lower CV risk than the other 3 agents by about 30%. There was no difference in microvascular risk among the agents in this study of relatively short-term disease. Side effects were not a major problem and no different than expected. Glargine and glimepiride were associated with less weight loss, while liraglutide had a particular benefit on weight. Glimepiride is associated with significantly more frequent incidents of severe hypoglycemia, though the rates of severe hypoglycemia were quite low. Liraglutide users reported significantly higher rates of nausea and had a higher early drop-out rate, but did not show a difference in continued use by the end of the study.  

In summary, the GRADE trial confirmed that glucose control in T2D is a progressive problem, as the addition of all 4 classes of medication failed to keep most patients in the target glucose range. However, basal insulin and GLP-1 RAs outperformed the other 2 classes. Sitagliptin has the poorest metabolic profile. One could argue that, based on overall metabolic control and concomitant weight benefits, less need for glucose monitoring, simple titration, apparent CV benefit, and insignificant hypoglycemia, GLP-1 RAs offer the best option as an agent to add to metformin. This conclusion is fortified by the fact that the agent used to represent this class in the study appears to be less effective in reducing glucose and weight and offers less convenience than the newer, once-weekly GLP-RAs available today.   

Type 2 diabetes (T2D) is a chronic, progressive disease marked by ongoing decline in insulin sensitivity and beta-cell function over time. Clinical trials have shown that lowering A1C to ∼7.0% (53 mmol/mol), especially after an early diagnosis, can markedly reduce the long-term complications of T2D. Metformin has become the generally recommended first therapeutic agent in treating T2D due to the drug’s long-term experience, effectiveness, and avoidance of hypoglycemia or weight gain. However, it is clear that additional agents are necessary to regain glucose control when metformin eventually fails due to the progressive nature of the disease.

Insufficient data on comparative efficacy and durability of effect has led to uncertainty in recommendations for the preferred second agent. Comparative effectiveness has been reported primarily in industry-sponsored trials of relatively short duration. With this in mind, the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) sponsored the Glycemia Reduction Approaches in Diabetes: A Comparative Effectiveness (GRADE) Study. This landmark, randomized controlled study was initiated in 2013, enrolling patients on metformin alone within 10 years of diagnosis of T2D. It involved 36 research sites in the United States with a mean follow-up of 5 years.

Key clinical point: Six biomarkers, including fine-specificity anti-citrullinated protein antibodies (ACPA) and anti-native protein antibodies, demonstrated a significant association with rheumatoid arthritis-associated interstitial lung disease (RA-ILD) and improved prediction sensitivity.

Major finding: Six fine-specificity antibody biomarkers, including immunoglobin G, to citrullinated (adjusted odds ratio [aOR] 3.47; 95% CI 1.71-7.01) and native (aOR 2.53; 95% CI 1.47-4.34) cyclic filaggrin 48-65 were associated with an increased risk for RA-ILD. Risk scores combining antibodies with clinical features with vs without biomarkers (score 5.9 vs 2.6) demonstrated higher sensitivity (67% vs 25%) and high specificity (≥93%) for developing RA-ILD at a threshold of 50% predicted probability.

Study details: This nested case-control study within an ongoing prospective registry included adult patients with incident RA-ILD (n = 84) and matched patients with RA without ILD (n = 233).

Disclosures: This study was supported by the US National Institute of Arthritis and Musculoskeletal and Skin Diseases. Several authors reported ties with various sources unrelated to this study.

Key clinical point: Smokers with a family history of rheumatoid arthritis (RA) may be considered a high-risk group who should be informed about increased smoking-associated RA risk and advised smoking cessation.

Major finding: Risk for RA was higher in individuals with vs without first-degree relatives affected with RA (adjusted hazard ratio [aHR] 4.49; 95% CI 3.96-5.10) and in current vs non-smokers (aHR 1.37; 95% CI 1.24-1.51), with the risk being markedly higher among smokers with a positive family history of RA (HR 6.44; 95% CI 4.61-9.00).

Study details: Findings are from a population-based cohort study that evaluated lifestyle factors and family relationships of 5,524,403 individuals with (n = 76,065) and without (n = 5,448,338) first-degree relatives affected with RA, of which 47,942 individuals developed RA.

Key clinical point: Rheumatoid arthritis-associated interstitial lung disease (RA-ILD) remains rare; treatment strategies have diversified over years, but high demand for analgesics and opioids suggests unmet needs in pain management.

Major finding: Between 2007 and 2020, the prevalence and incidence of ILD among patients with RA were 1.6%-2.2% and 0.13%-0.21% per year, respectively, and biologic disease-modifying antirheumatic drug (DMARD) use increased from 16% to 24%, whereas glucocorticoid, conventional synthetic DMARD, and nonsteroidal anti-inflammatory drug use declined from 84% to 68%, 83% to 55%, and 62% to 38%, respectively. However, analgesic use increased and ≈30% of patients received opioids.

Study details: This study analyzed insurance claims data of 98,435 and 142,657 patients diagnosed with RA, 257 and 1484 with prevalent ILD, and 18 and 90 with incident ILD in 2007 and 2020, respectively.

Key clinical point: Rheumatoid arthritis (RA) is associated with a high risk for end-stage renal disease, with the risk being prominent among relatively young and comorbidity-free individuals and those who consume alcohol.

Major finding: Patients with RA were at a significantly higher risk for end-stage renal disease compared with those without RA (adjusted hazard ratio 2.153; 95% CI 1.948-2.379), particularly among patients who were relatively young (P_interaction < .001), those without comorbidities (P_interaction < .001), and those who consumed alcohol (P_interaction  =  .021).

Study details: This retrospective population-based study included 154,997 patients with RA and 774,985 age- and sex-matched individuals without RA.

Disclosures: This study was supported by grants from the Chonnam National University Hospital Biomedical Research Institute and National Research Foundation of Korea, funded by the Korea Government. The authors declared no conflicts of interest.
