The author reports a case of a large cyst on the left mandible that clinically was misconstrued as an adamantinoma. The patient, a man, aged 43, complained of a purulent discharge from a fistula after the extraction of the left mandibular wisdom tooth and of a slight swelling of its origin, which began about 16 years ago and gradually incresed in size. Through scrutiny of microscopic examination however, it proverd to be a so-called Mayrhofer's toothless root cyst. On this case an absence of a history of infected teeth has been recognized. The reporter assumed that it probably developed from a long standing granuloma or hematoma after the tooth extraction.
