Soft tissue localized sarcoidosis is rarely reported in the literature as well as associated cutaneous vasculitis. We present the case of a 34 year old patient with a history of a swelling in the distal left index finger phalanx evolving since 1 month who was admitted for a macular non pruritic rash of his legs. Laboratory findings and radiological investigations have guided the diagnosis of systemic sarcoidosis which was confirmed by finger biopsy. Cutaneous biopsy revealed associated vasculitis. The aim of this case report is to highlight that in case of progressive swelling in soft tissue associated to cutaneous vasculitis, systemic sarcoidosis is a possible differential diagnosis. Biological and radiological work out may guide the diagnosis and biopsy will confirm it.
