Angioleiomyoma of the Parotid Gland Fed by the Superficial Temporal Artery

Angioleiomyoma in the head and neck area is rarely observed. This report introduces 2 cases of angioleiomyoma discovered in the parotid gland, particularly with the superficial temporal artery (STA) as the feeding vessel. Each patient was evaluated preoperatively by clinical manifestation and computed tomography scan, but the difficulty was encountered due to nonspecific radiologic features of angioleiomyoa. Surgical intervention was performed for precise diagnosis and treatment. The tumors were fed from the STA, with the diagnosis of venous type parotid angioleiomyoma. To our knowledge, there have been only one previous report of angioleiomyoma of the parotid gland fed from STA in the literature. Once parotid tumor is discovered, although rare, the possibility of angioleiomyoma should be considered, and the authors recommend prompt surgical excision for accurate diagnosis and treatment.
