Abstract

Abstract : Abstract: Myoepithelial carcinoma is an exceedingly rare malignant neoplasm that most frequently occurs in the salivary gland. We here report a case of myoepithelial carcinoma in a 57-year-old man. Unenhanced and contrast-enhanced CT scans showed an ill-defined, heterogeneous, contrast-enhancing mass in the left parapharyngeal space, which suggested malignancy. 18 F-FDG PET/CT showed a hypermetabolic mass and multiple FDG-avid lymph nodes in the bilateral cervical regions. An incision biopsy was performed, and the pathological examination confirmed the mass to be a myoepithelial carcinoma.
