A Case of Leiomyosarcoma of the Parotid Gland / 대한이비인후과학회지

ABSTRACT

Leiomyosarcoma is a malignant tumor originating from the smooth muscle tissue, found mostly in the genitourinary tract, gastrointestinal tract and peritoneum. However, leiomyosarcoma of the parotid gland is extremely rare as there is only smooth muscle in the blood vessels of the parotid gland. There has been a only single case of metastatic leiomyosarcoma reported in the English journal. Herein we report an extremely rare case of leiomyosarcoma of the parotid gland of a 66-year-old man who initially suffered from primary renal leiomyosarcoma.
