Pustular psoriasis with chronic recurrent multifocal osteomyelitis and spontaneous fractures.

Chronic recurrent multifocal osteomyelitis is rarely associated with pustular psoriasis in children. We describe a child with severe pustular psoriasis in whom multiple fractures, bone deformities, and severe growth failure from chronic recurrent multifocal osteomyelitis developed. The recurrent fractures led to an incorrect assumption of child abuse. Both the bone disease and pustular psoriasis responded to treatment with etretinate.
