Partial lipodystrophy presenting with myopathy.

A girl with partial lipodystrophy is described presenting with muscle weakness and developmental delay several years before lipoatrophy became apparent. The patient subsequently developed epilepsy, fatty liver, secondary amenorrhoea, hirsutism, insulin-resistant diabetes mellitus, hyperlipidaemia, and hypothyroidism. She remains weak with poor exercise tolerance. This case illustrates an atypical presentation of the Barraquer-Simon syndrome.
