Abstract

Carcinoma ex pleomorphic adenoma is one of the rare malignant tumors arising in the salivary glands. Parotid gland is the most frequently affected site, while the other minor salivary glands have much lower incidence rates. There has been no clinical report of the carcinoma ex pleomorphic adenoma developed in the maxillary sinus. Carcinoma ex pleomorphic adenoma is very malignant and its prognosis is rarest among those of parotid gland tumors. We experienced a 24-year-old male patient who had a bulging mass on his left infraorbital area for 18 months. A carcinoma ex pleomorphic adenoma arising in the left maxillary sinus was diagnosed and medial maxillectomy, postoperative chemotherapy and concurrent radiotherapy were done. So far we have followed up the patient for 15 months and there is no sign or symptom of recurrence or metastasis.
