Pigmented purpuric dermatosis-like sarcoidosis

Abstract

Sarcoidosis is a chronic multisystem granulomatous disease of unknown origin. Recently, a purpuric variant of cutaneous sarcoidosis resembling pigmented purpuric dermatosis (PPD) has been documented. Herein, we describe another unusual case with clinical features mimicking PPD, characterized by brownish macules and flat-topped papules with a slightly purpuric component on the legs and dorsum of the feet and histopathological features consistent with sarcoidosis. We designated this unusual clinical presentation as "PPD-like sarcoidosis".

Keywords: atypical; pigmented purpuric dermatosis; sarcoidosis.
