Abstract

The differential diagnosis of lesions in buccal area include lipoma, neurofibromas, epidermoid cyst, salivary ducts calculus, hemangioma, lymphadenopathy. Accessory parotid glands is defined as salivary gland tissue adjacent to the parotid duct, but separated from the body of parotid and it may be found in approximately 20% of human parotid glands. The appearance of an accessory parotid tumor is rare, with a reported frequency of 7.7% of all parotid neoplasm. Angiomyoma, which is also termed angioleiomyoma, is a rare solitary subcu-taneous tumors arising from the vascular smooth muscle. It often occur in the extremities and is rarely found in buccal area. We present 2 cases of rare tumor in buccal mass and resected surgically without facial nerve palsy.
