[Progressive spinal muscular atrophy of proximal location in adults]

The authors report two cases of familial progressive muscular atrophy of proximal localization, with late onset of signs which was associated with involvement of the motor nucleus of trigeminal nerve and hypoglossus nerve nucleus as well as with presence of gynaecomastia. Cases of coexistence of gynaecomastia with spinal muscular atrophy are rare in the literature and the present report may serve for explanation whether the association of these signs is accidental or whether it is a separate nosological entity.
