Carcinosarcoma of minor salivary gland of lower lip with pelvic metastasis: A case report

Carcinosarcoma of salivary gland is a rare and aggressive tumor composed of both carcinomatous and sarcomatous components which metastasize together. Most tumors arise in parotid gland from a preexisting pleomorphic adenoma. Methods and Results: We report a case of carcinosarcoma of minor salivary gland of lower lip with subsequent infiltration to mandible and pelvic metastasis after recurrence. The patient was a 38 year old man who underwent surgical resection and adjuvant chemo radiotherapy and demonstrates recurrence after 9 months with metastasis to left iliac fossa. Conclusion: Carcinosarcoma of minor salivary gland is an extremely rare malignancy with poor prognosis and is best managed by combination of surgical resection and postoperative radiation.
