Abstract
- Osteoma cutis is a rare, benign, frequently congenital tumor of the skin composed of bone tissue, showing neither invasive nor metastasizing tendency. The term osteoma cutis is applied to cases of primary cutaneous ossification in which there is no evidence of Albrights hereditary osteodystrophy. Congenital platelike osteoma cutis is a clinically different variant of primary cutaneous osteoma. We report the case of a 10-month-old male infant who presented with two walnut-sized firm, poorly demarcated plaques containing pinhead-sized erythematous papules on the abdomen and the right leg and multiple variably sized erythematous subcutaneous nodules on the left leg sinee birth. The initial lesions did not enlarge nor did new lesions develop. A biopsy specimen of the abdominal lesion showed bony plate and cartilaginous structures in the subcutaneous fat tissue. There was no history of any skin disease prior to the development of osteoma.
