Darier-Roussy Subcutaneous Sarcoidosis: A Case-Based Review

Abstract

Sarcoidosis is a systemic granulomatous inflammatory condition characterized by varied clinical manifestations, with a higher prevalence observed in individuals aged 25 to 40 and women over 50. Typical presentations involve symmetric involvement of hilar and mediastinal lymph nodes, followed by lung involvement. While initial stages are often asymptomatic, the disease can impact various organs. Cutaneous involvement, observed in up to a quarter of patients, includes lupus pernio, papules, plaques, erythema nodosum, and occasionally subcutaneous nodules. Subcutaneous sarcoidosis, once considered rare, is now increasingly recognized. We present a case of Darier-Roussy sarcoidosis in a middle-aged man, demonstrating multiple painless subcutaneous nodules confirmed through biopsy. Our findings suggest that Darier-Roussy sarcoidosis typically manifests early in the disease course, indicating non-severe systemic involvement. Additionally, our patient responded well to hydroxychloroquine treatment, suggesting a positive outcome.
