Abstract

Myoepithelial carcinoma, also called malignant myoepithelioma, is an extremely rare tumor of the salivary gland type. It is defined as a malignant neoplasm in which the tumor cells exhibit exclusively myoepithelial differentiation. Our case is a 48-year-old patient with no specific history who was presented to the hospital emergency room for respiratory difficulty and dysphagia progressively evolving for 08 weeks. A cervical CT was done which revealed a hypodense tumor process in T1 of 4 cm long axis obstructing the trachea well limited and richly vascularized. The diagnosis of tracheal myoepithelial carcinoma was made after histological and immunohistochemical analysis on a biopsy pending analysis of the operative specimen. Treatment remains initially surgical with appropriate postoperative radiotherapy and chemotherapy.

Summary

INTRODUCTION

Myoepithelial carcinoma is a rare tumor that mainly affects the salivary glands, breast, and rarely soft tissue. Tracheal myoepithelial carcinoma does not fall under the most recent classification of the World Health Organization (WHO) which defines a set of tumors called the salivary gland type of the lung of which it is not part [4]. It is an extremely rare tumor; only 16 cases reported in the literature [5,6]. We report a case of tracheal myoepithelial carcinoma diagnosed as a result of asphyxiation in a 45-year-old emergency patient, whose endoscopic examination found a polypoid tumor obstructing the trachea. The diagnosis of tracheal myoepithelial carcinoma was made pending analysis of the operative specimen
