## Abstract

Sarcoidosis is a systemic inflammatory disease affecting multiple organs including the skin, lungs, and kidneys. This case report describes a man in his late 20s presenting with recurrent kidney stones and a one-year history of progressive, asymptomatic lesions on his scalp, forehead, trunk, and feet, with dyspnea on exertion. Biopsy confirmed cutaneous sarcoidosis, and further evaluation revealed pulmonary and renal involvement. He was treated with hydroxychloroquine and prednisone, leading to improvement in skin lesions. This case highlights the importance of recognizing cutaneous manifestations as potential indicators of systemic sarcoidosis, and the need for a comprehensive, multidisciplinary approach to diagnosis and management.
