title: Myoepithelial carcinoma inside of maxilla bone: A case report.
abstract: Myoepithelial carcinoma (MC) is a rare type of carcinoma occurring mainly in the parotid gland, while other carcinomas occur in submandibular or the accessory glands of the oral cavity. They may arise from the glands of the respiratory tract. However, primary MC of the bone is extremely rare. In the present study, a rare case of a 41-year-old woman with MC in the maxilla bone was reported. Following misdiagnosis as a bone cyst, a local excision was performed. The patient then presented with an extremely high malignancy and showed no response to chemoradiation treatment. The bone cyst was thought to be MC, thus early diagnosis with complete surgical excision was highly important. After confirmation of MC, a secondary extensive surgery may be crucial, following the primary local surgical resection.
