A Case of Salivary Duct Carcinoma Ex Pleomorphic Adenoma of Parotid Gland / 대한이비인후과학회지

ABSTRACT

Carcinoma ex pleomorphic adenoma of the salivary gland is a relatively uncommon tumor that accounts for roughly 4% of all malignancies at this location. The lesion occurs when a malignant tumor arises in the epithelial component of a pleomorphic adenoma. It usually arises in the parotid gland. Typically, it is a high grade carcinoma, frequently leading to metastasis and disease-related death. We experienced a case of a salivary duct carcinoma that arose in the epithelial component of a pleomorphic adenoma in the parotid gland with neck metastasis. After total parotidectomy and modified radical neck dissection, he was given 10, 980 cGy of radiation postoperatively for 7 weeks. The clinicopathologic feature of this tumor are presented with a review of literatures.
