An 18-year-old girl had a progressive enlarging plate of subcutaneous bone in the scalp since birth. Histologic examination of the lesion showed typical osteoma cutis. There was no history of any skin disease prior to development of the osteoma. Frequently congenital and usually located on the scalp, platelike osteoma is a rare variant of osteoma cutis.
A 27-year-old woman and a 13-year-old girl diagnosed with juvenile dermatomyositis in childhood developed clinical findings of partial lipodystrophy 10 years after diagnosis. Exhaustive clinical and laboratory examinations showed an association with other abnormalities: hypertrichosis, steatohepatitis, and an abnormal insulin response to the glucose loading test in the first patient. Hypertrichosis, steatohepatitis, insulin-resistant diabetes mellitus, and acanthosis nigricans were observed in the second patient. Renal function was normal in both patients. Although a localized form of lipodystrophy has been reported associated with connective tissue disease (connective tissue lipoatrophy), the partial form has been infrequently described in association with juvenile dermatomyositis.
