Abstract:
Myoepithelial carcinoma is a very rare malignant tumor accounting for less than one percent of the salivary gland neoplasms. This uncommom tumor, showing almost exclusively tumor cells with myoepithelial differentiation, is most commonly diagnosed in the parotid gland and in the minor silivary glands of the palate. We report a 77-year-old woman with myoepithelial carcinoma originating from maxillary sinus, one of the most unusual locations. The patient presented with progressive nasal obstruction and signs of a space-occupying lesion in the left maxillary sinus. A frozen biopsy identified a malignant tumor and a radical maxillectomy was performed. Histology confirmed the presence of a malignant myoepithelial carcinoma. Patient was followed up for one year without any recurrence or distant metastasis.
