Epithelial-myoepithelial carcinoma of the nasopharynx

Abstract

We present a patient with a rare epithelial-myoepithelial carcinoma of the nasopharynx with a typical biphasic histopathologic pattern. Immunohistochemical findings support the concept that the inner cells differentiate to ductal epithelium and the outer cells to myoepithelium. In this patient complete excision of the tumor and reconstruction with a pedicled sternocleidomastoid myocutaneous flap were performed. A DNA diploid pattern from flow cytometric study indicates a favorable prognosis. There was no recurrence nor metastasis for 55 months.
