Deskripsi
Anti-tumor necrosis factor α (TNF-α) biologic agents are used for treating refractory sarcoidosis. However, sarcoidosis-like epithelioid cell granulomas may develop during anti-TNF-α treatment. A 63-year-old man suffering from rheumatoid arthritis was treated with oral methotrexate and methylprednisolone for 4 years. He subsequently started biweekly subcutaneous injections of certolizumab pegol. Three months later, light red follicular papules developed on his chest and they spread over the trunk and bilateral upper arms. Histopathology of a lesion showed a sharply demarcated noncaseating epithelioid cell granuloma with multi-nucleated giant cells in the upper perifollicular area. The follicular papules subsided following discontinuation of certolizumab pegol. Folliculitis-like lichenoid sarcoidosis should be included among the adverse cutaneous reactions of anti-TNF-α treatment.
