In this study, we report a case of mucosal melanoma from the eustachian tube which was surgically managed, followed by chemoradiotherapy. A 53-year-old man presented with a history of recurrent idiopathic hemotympanum and a dark red mass in the nasopharynx protruding from the eustachian tube orifice. Under an impression of mucosal melanoma from the eustachian tube, en-bloc surgical removal was performed using the infratemporal fossa approach type C combined with a transnasal endoscopic approach followed by postoperative chemoradiotherapy. However, the disease progressed to lung metastasis, and the patient died of the disease at 13 months postoperatively. The presenting case showed a poor progression despite a margin-free surgical resection followed by chemoradiotherapy. Additional trial of new treatment options is necessary to improve the poor prognosis.\n\nCite this article as: Kang YJ, KIm MB, Hong SD, Cho Y-S. Mucosal melanoma of eustachian tube: A case report.
