We recently encountered a rare case of osteoma of the mandibular. The patient was a 19-year-old woman. Nine years earlier, she had noticed a mass in the left mandibular region. She had an operation. After 29 years, she had a relapse. Treatment was repeated. The pathological examination of a specimen of the mandible showed spongiosum.
