[Shulman's syndrome. Diffuse fasciitis with eosinophilia. A differential diagnosis from polymyositis (author's transl)].

A case of diffuse fasciitis with eosinophilia is reported. The clinical pattern of this disease has some resemblance with polymyositis. In 1974, Shulman described this syndrome as a new entity. The differential diagnosis of those inflammatory and sclerodermatous changes in the perimuscular fascia is considered. An histological, immunological and electrophysiological investigation has been performed. We propose an auto-immunological mechanism in the etiopathogenesis of this syndrome.
