Abstract
- Among skin disorders associated with changes to the bony tissue or abnormalities of calcification, osteoma cutis is a rare, benign tumor of the skin composed of compact bone. Osteoma cutis is primary ossification without preceding skin disease, trauma or evidence of Albright's hereditary osteodystrophy. A 59-year-old man presented with a firm erythematous nodule containing centrally punctuated ulcer on the right mandibular angle. A biopsy specimen showed calcification and ossification with many osteocytes, which had extruded through the perforating epidermal channel. We herein report a rare case of perforating osteoma cutis.
