[Erythrodermic sarcoidosis].

Cutaneous involvement is relatively frequent in patients with sarcoidosis. The histologic evidence of typical non-caseating granulomas differentiates specific from non-specific skin lesions. Among specific cutaneous lesions of sarcoidosis, erythroderma is exceedingly rare. We report here a case of erythrodermic sarcoidosis. The differential diagnosis and the possible correlation with cutaneous T-cell lymphomas are discussed.
