[Chronic X-linked recessive bulbospinal amyotrophy (Kennedy-Stefanis type). Apropos of a case].

A new observation of chronic X-linked recessive spinal amyotrophy is reported. This series of cases fits the description of Kennedy-Stefanis chronic spinal amyotrophy, whose main characteristics are: sex-linked recessive inheritance, weakness and bulbo-spinal amyotrophy with proximal predominance, facio-lingual fasciculations, areflexia, gynecomastia in half of cases, very slowly progressive course, neurogenic EMG with normal nerve conduction velocities, and neurogenic muscle biopsy.
