초록

Osteoma is a common benign tumor, which is consisted of mature osseous tissue. But it is not found commonly in the intraoral lesion. Actually, since Monsserat reported the first case of lingual base osseous choristoma in 1913, there were fewer than 100 cases of lingual osseous choristoma have been reported. A 23-year-old woman, without any underlying disease except dyslipidemia, visited out-patient clinic presenting intermittent pharyngeal pain with globus pharyngeus and hoarseness for 4 months. Laryngoscopy revealed an 1 cm-sized, well-defined, smooth-surface whitish solid mass on the right side of tongue base. Under the impression of a benign tongue base tumor such as granuloma, the mass was excised by monopolar electrocoagulator under general anesthesia. Later, the mass was identified as osseous choristoma. We reported a rare case of lingual base osseous choristoma with literature review.
