A Case of Metachronous Carcinosarcoma and Squamous Cell Carcinoma of the Both Parotid Glands / 대한이비인후과학회지

ABSTRACT

Carcinosarcoma of the parotid gland is rare. Furthermore, metachronous bilateral double primary carcinoma of the parotid gland is very rare. We report a case of metachronous bilateral double primary Carcinosarcoma and Squamous cell carcinoma of both parotid glands in the same patient. He received operation and postoperative radiotherapy for a left parotid gland cancer. Four years later, the right parotid gland cancer developed, which was treated by excision followed by radiotherapy. At follow-up, he remained free of disease.
