A Man with Infiltrated and Indurated Plaque on the Forehead

Osteoma cutis, a rare benign condition characterized by the presence of osseous nodules are composed of lamellar bone with osteocytes in the center and osteoclasts in the external area, in the reticular layer of the skin. Osteoma cutis can be either primary, arising de novo in healthy skin, or secondary, developing in association with pre-existing neoplastic or inflammatory skin lesions. We present a 25-year-old man with plaque-like osteoma cutis.
