Laryngeal Primary Myoepithelial Carcinoma: Case Report and a Systematic Review of Literature

Abstract

Myoepithelial carcinoma of the head and neck is a rare malignant tumor that usually arises from the salivary glands but rarely from the larynx. Here, we describe 11 cases (one treated by us and 10 previously published) of laryngeal myoepithelial carcinoma. Our patient was a 60-year-old male who initially presented with hoarseness and throat pain. The patient had suffered from continuing hoarseness and throat pain for one month before he consulted an otorhinolaryngologist. Computed tomography (CT) scan showed a polypoid tumor involving the right vocal cords. Biopsy was performed, and the disease was pathologically diagnosed as myoepithelial carcinoma of the larynx by hematoxylin-eosin and immunohistochemical staining. The total follow-up period was 15 months. Repeated laryngoscopies or CT scans revealed no recurrence or residual lesion during the post-surgical course.
