Ten cases of juvenile muscular atrophy of unilateral or rarely bilateral upper limbs were reported. All patients have not familial incidence. Predominantly males in teen-agers are affected. Juvenile onset, localized unilateral or rarely bilateral muscular atrophy showing unique distribution in the upper limb and non-progressive course in the stage are characteristic features of this disorder. Objective sensory in all patients is not. Electromyogram shows high amplitude action potentials and muscular biopsy the picture of neurogenic atrophy.
