RESUMEN
Sarcoidosis is an idiopathic multisystemic granulomatous disease that mainly affects the lungs. Darier-Roussy subcutaneous sarcoidosis is among the specific and least encountered skin manifestations of sarcoidosis. In this case study, we report how subcutaneous sarcoidosis could mimic multiple abscesses presentation and hinder reaching a definitive diagnosis. A 65-year-old female presented with five, multiple, deep-seated skin lesions on the forearm, chest, and scalp. The lesions showed redness and tenderness. The patient also experienced arthralgia in the right ankle. Laboratory workup of the patient showed a high erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and white blood cell (WBC) count. The patient was suspected to have multiple abscesses, which were managed with antibiotics with no response. Thus, a computed tomography (CT) scan of the chest was done and showed mediastinal lymphadenopathy. A biopsy was taken from one of the right forearm skin lesions, and it revealed characteristic features consistent with sarcoidosis. The patient was managed with hydroxychloroquine and a tapering dose of prednisone. Therefore, subcutaneous sarcoidosis should be included in the differential diagnosis of subcutaneous lumps.
