A case of osteoma cutis / 대한피부과학회지

ABSTRACT

Osteoma cutis is a primary cutaneous ossification, which has no preceding trauma or skin disease and no evidence of Albrights hereditary osteodystrophy n the patient or his family. The lesion appears as hard, round to irregular, sharply defined tumor of varying size within the skin or subcutis, and color ranges from flesh-colored to purple or brown. We report herein a case of osteoma cutis in a 32-year-old female, who had a 1 x 1cm sized, asymptomatic, round, flesh colored, hard nodule on the right side of her forehead for 5 years. Histopathologic examination showed mature bone with many ostocytes, osteoblasts, cement lines and Haversian canals in the dermis.
