A case of primary osteoma cutis on the back is reported. This case showed an unusual form of calcification on soft x-ray. Histologic examination disclosed mature bone in the subcutis. There was no history or evidence of any skin disease prior to the development of the osteoma. The literature is reviewed and discussed.
