[Disseminated cutaneous granulomatosis]

Abstract

The disseminated cutaneous granulomatosis (DCG) are heterogeneous cutaneous diseases histologically characterized by a granulomatous infiltrate. The most frequent cutaneous granulomatosis is sarcoidosis, but many other causes can be found, because DCG are probably a skin granulomatous reaction to different stimuli: infectious, inflammatory, neoplastic, metabolic or chemical. The histopathological examination is useful for the diagnosis of DCG, but gives rarely an etiological diagnosis. In this article, we will propose a strategy for the etiological diagnosis of DCG, and propose therapeutic recommendations based on recent data from the literature.
