Mucha-Habermann disease in children -- the association with rheumatic diseases.

Two children are described who developed Mucha-Habermann disease as infants. One boy had juvenile rheumatoid arthritis that ran a progressive course over 10 years, although his skin disease responded to a low dose of corticosteroids. One girl had polyarthritis associated with onset of her rash but both resolved over several years without treatment. She has since developed scleroderma followed by a reappearance of her skin lesions.
