[Neuromuscular manifestation of sarcoidosis (author's transl)].

Abstract

Three of our own observations of neuromuscular manifestation of sarcoidosis are presented. In two cases, a slowly progredient myopathic syndrome was evident. This syndrome developed in mid-life and showed asymmetrical distribution. In another case, a polyneuropathic syndrome was seen, which mainly affected motor function of the lower extremities. None of these patients had typical findings on chest x-rays. Histological proof of granulomatous alterations of skeletal muscle was the first indication of sarcoidosis. With reference to a further observation, the diagnostical value of muscle biopsy in sarcoidosis without neuromuscular manifestation is discussed.
