Key result
Complete resection of isolated external auditory canal myxoma shows no recurrence at 1 year.
Why the study?
Isolated myxoma of the external auditory canal is extremely rare, with only 5 cases previously reported in the literature.
Case Report (n=1)
Isolated myxoma of the external auditory canal is an extremely rare benign tumor that can be successfully managed with complete surgical resection.
Supports resection for rare external auditory canal myxoma; hypothesis-generating from single case report.
Myxoma is a benign myxoid tumor of connective tissue that develops primarily in the heart. At the level of the external auditory canal, it is extremely rare. It can be isolated or associated with Carney syndrome. Only 5 cases of isolated myxoma of the external auditory canal have been reported in the literature. We present the case of a 53-year-old patient who consulted for a hearing loss that has been evolving for 3 years. Otoscopy revealed a mass filling the external auditory canal. The scan showed a total filling of the external auditory canal with a homogenous sessile neoformation of 20 × 10 mm. This mass was completely resected and the histological examination showed spindle-shaped and star-shaped cells against an abundant myxoid background, which was consistent with myxoma. All the tests, done to eliminate Carney syndrome, did not reveal any abnormalities. The postoperative course was favorable, and no complications were noted. The patient was under follow-up. There was no recurrence 1 year after surgery.

Hasnaoui et al. (2020) conducted a case report in Isolated myxoma of the external auditory canal (n=1). Complete surgical resection was evaluated on Recurrence. Complete surgical resection of an isolated myxoma of the external auditory canal resulted in a favorable postoperative course with no recurrence at 1 year.
