A 32-year old female visited our hospital complaining of anabnormal sensation in the anterior neck. Posterior rhinoscopy revealed a tooth-like mass in her epipharynx on the left side.
A Davis mouth-opener was applied, and the mass was removed with an ecraseur under general anesthesia. The pathological diagnosis was ectopic tooth in the epipharynx.
Including this case, 136 patients (143 teeth) with dental abnormalities have been reported in the Japanese literature. Most of these abnormalities were in the nasal cavity.
The etiology in this case may have been movement of rudiment No. 8 with growth in the epipharynx.
