초록
Myxomas are benign mesenchymal tumors that rarely occur in the head and neck. When they occur in the head and neck region, they are mostly involved in the mandible and maxilla areas. Myxomas arising from subcutaneous soft tissues of the external auditory canal (EAC) are very rare. We present a case of a 78-year-old female patient who had been suffering from left- sided hearing disturbance for 6 months. The otoscopic examination revealed a round mass arising from the anterior and superior wall of EAC, almost completely filling the EAC and partially invading the outer layer of the tympanic membrane. This mass was completely re- sected via microscopic excision and tympanoplasty, and the following histopathological ex- amination revealed the mass to be consistent with a myxoma. Unfortunately, a myxoma reap- peared at the superior wall of the auditory canal, 6 months after the surgery. The patient is currently being managed with monthly marsupialization without reoperation.
