Granuloma annulare (GA) is a benign, cutaneous, granulomatous disease of unclear etiology. Typically, GA presents in young adults as asymptomatic, annular, flesh-colored to pink papules and plaques, commonly on the upper and lower extremities. Histologically, GA is characterized by mucin deposition, palisading or an interstitial granulomatous pattern, and collagen and elastic fiber degeneration.1
Granuloma annulare has been associated with various medications and medical conditions, including diabetes mellitus, hyperlipidemia, thyroid disease, and HIV.1 More recently, immune-checkpoint inhibitors (ICIs) have been reported to trigger GA.2 We report a case of nivolumab-induced GA in a 54-year-old woman.
Case Report
A 54-year-old woman presented with an itchy rash on the upper extremities, face, and chest of 4 months’ duration. The patient noted that the rash started on the hands and progressed to include the arms, face, and chest. She also reported associated mild tenderness. She had a history of stage IV non–small-cell lung carcinoma with metastases to the ribs and adrenal glands. She had been started on biweekly intravenous infusions of the ICI nivolumab by her oncologist approximately 1 year prior to the current presentation after failing a course of conventional chemotherapy. The most recent positron emission tomography–computed tomography scan 1 month prior to presentation showed a stable lung mass with radiologic disappearance of metastases, indicating a favorable response to nivolumab. The patient also had a history of hypothyroidism and depression, which were treated with oral levothyroxine 75 μg once daily and oral sertraline 50 mg once daily, respectively, both for longer than 5 years.
Physical examination revealed annular, erythematous, flat-topped papules, some with surmounting fine scale, coalescing into larger plaques along the dorsal surface of the hands and arms (Figure 1) as well as the forehead and chest. A biopsy of a papule on the dorsal aspect of the left hand revealed nodules of histiocytes admixed with Langerhans giant cells within the dermis; mucin was noted centrally within some nodules (Figure 2). Periodic acid–Schiff staining was negative for fungal elements compared to control. Polarization of the specimen was negative for foreign bodies. The biopsy findings therefore were consistent with a diagnosis of GA.
A 3-month treatment course of betamethasone dipropionate 0.05% cream twice daily failed. Narrowband UVB phototherapy was then initiated at 3 sessions weekly. The eruption of GA improved after 3 months of phototherapy. Subsequently, the patient was lost to follow-up.
Comment
Discovery of specific immune checkpoints in tumor-induced immunosuppression revolutionized oncologic therapy. An example is the programmed cell-death protein 1 (PD-1) receptor that is expressed on activated immune cells, including T cells and macrophages.3,4 Upon binding to the PD-1 ligand (PD-L1), T-cell proliferation is inhibited, resulting in downregulation of the immune response. As a result, tumor cells have evolved to overexpress PD-L1 to evade immunologic detection.3 Nivolumab, a fully human IgG4 antibody to PD-1, has emerged along with other ICIs as effective treatments for numerous cancers, including melanoma and non–small-cell lung cancer. By disrupting downregulation of T cells, ICIs improve immune-mediated antitumor activity.3
However, the resulting immunologic disturbance by ICIs has been reported to induce various cutaneous and systemic immune-mediated adverse reactions, including granulomatous reactions such as sarcoidosis, GA, and a cutaneous sarcoidlike granulomatous reaction.1,2,5,6 Our patient represents a rare case of nivolumab-induced GA.
Recent evidence suggests that GA might be caused in part by a cell-mediated hypersensitivity reaction that is regulated by a helper T cell subset 1 inflammatory reaction. Through release of cytokines by activated CD4+ T cells, macrophages are recruited, forming the granulomatous pattern and secreting enzymes that can degrade connective tissue. Nivolumab and other ICIs can thus trigger this reaction because their blockade of PD-1 enhances T cell–mediated immune reactions.2 In addition, because macrophages themselves also express PD-1, ICIs can directly enhance macrophage recruitment and proliferation, further increasing the risk of a granulomatous reaction.4
Interestingly, cutaneous adverse reactions to nivolumab have been associated with improved survival in melanoma patients.7 The nature of this association with granulomatous reactions in general and with GA specifically remains to be determined.
Conclusion
Since the approval of the first PD-1 inhibitors, pembrolizumab and nivolumab, in 2014, other ICIs targeting the immune checkpoint pathway have been developed. Newer agents targeting PD-L1 (avelumab, atezolizumab, and durvalumab) were recently approved. Additionally, cemiplimab, another PD-1 inhibitor, was approved by the US Food and Drug Administration in 2018 for the treatment of advanced cutaneous squamous cell carcinoma.8 Indications for all ICIs also have expanded considerably.3 Therefore, the incidence of immune-mediated adverse reactions, including GA, is bound to increase. Physicians should be cognizant of this association to accurately diagnose and effectively treat adverse reactions in patients who are taking ICIs.

Practice Points
- Immune-related adverse events (irAEs) frequently occur in patients on immunotherapy, with the skin representing the most common site of involvement.
- Although rare, granulomatous reactions such as granuloma annulare increasingly are recognized as potential irAEs.
- Clinicians should be aware of this novel association to accurately diagnose and effectively treat adverse reactions in patients receiving immunotherapy.
