Myoepithelial Carcinoma Occurring on the Ascending Aorta

Abstract

Myoepithelial carcinomas are rare malignant tumors that primarily develop in exocrine glands. We present a case of myoepithelial carcinoma located on the aorta of a 39-year-old Japanese woman. Complete resection of the tumor and aorta was performed using cardiopulmonary bypass. Histologic and immunohistochemical analyses confirmed the diagnosis. The patient was symptom-free after the operation, and no tumor recurrence was observed during 7 years of follow-up. We report a rare myoepithelial carcinoma occurring on the aorta.
