Abstract

It is rare for osteoma to arise in the buccal soft tissue. Only six cases arising in this site have been reported in the literature abroad. The case described here was an osteoma arising in the right buccal soft tissue of a 65-year-old Japanese male. Its size was 26× 21× 8mm. Microscopically, the outer surface of the tumor consisted of lamellar bone, and the inside was fatty bone marrow with thin bone trabeculae. Abundant osteoblasts surrounded newly formed osseous tissue. The mass was surrounded by a fibrous connective tissue capsule. The microscopic findings were basically the same as an osteoma of the jaw.
