Manifestations cutanées de la sarcoïdose: revue de la littérature et de 53 observations personnelles

: The authors review the literature and 53 personal cases, and describe the very variable appearances of the skin lesions in sarcoidosis: these may be divided into two main groups: non-specific "vasculitis" mainly represented by acute lesions of the erythema nodosum type, and specific polymorphic lesions often difficult to diagnose clinically and requiring skin biopsy. As in previous reports, the personal cases bring out a number of special features: silicotic granulomatous sarcoid like lesions may be observed in authentic cases of sarcoidosis; lesions identical to those described in systemic sarcoidosis may appear in isolation without other localisations. Is this cutaneous sarcoid? or sarcoid-like granulomata of unknown origin? The treatment of sarcoid skin lesions is described briefly.
