Primary myoepithelial carcinoma of the larynx: case report and review of the literature.

Myoepithelial carcinoma of the head and neck is a rare malignant tumor and usually arises from the salivary glands. The larynx is an uncommon condition of involvement in myoepithelial carcinoma. Here we describe the forth reported case of myoepithelial carcinoma in the larynx. It affected a 78-year-old male who presented initially with hoarseness and bloody sputum. The patient had suffered from continuing hoarseness and bloody sputum for three months before he consulted an otorhinolaryngologist one month ago. Computed tomography 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 eleven months. The repeated laryngoscopy or CT scan revealed no recurring or residual lesion during the post-surgical course.
