Abstract

Hybrid carcinoma of the salivary gland is a very rare entity that has been described only in the parotid and palate. The occurrence of a hybrid carcinoma of maxillary sinus has not been reported. The diagnosis of hybrid carcinoma is important particularly when the components of tumor have different biologic behaviors. Diagnosis and treatment require a high index of suspicion, especially when the tumor is an epithelial-myoepithelial carcinoma, pathological effort to look for a more aggressive accompanying tumor, and proper oncologic treatment. We describe a case of 26-yr-old woman with a hybrid carcinoma composed of epithelial-myoepithelial carcinoma with an adenoid cystic carcinoma component (cribriform pattern) in the right maxillary sinus with a brief review of the relevant literature.
