A Case of Salivary Duct Carcinoma in Parotid Gland / 대한이비인후과학회지

ABSTRACT

The salivary duct carcinoma(Speichelgangcarcinoma) was first applied by Kleinsasser et al7) to a group of carcinomas of the salivary glands that histologically resembled ductal carcinoma of the breast. The criteria for the diagnosis of salivary duct carcinoma are circumscribed epithelial nests, having a papillary, cribriform, and/or solid architecture coupled with central necrosis. The neoplasm occurs beyond the age of 50(median 63 years). Its biologic behavior is highly aggressive; the metastatic and tumor-related death rates were 75% and 73%, respectively. All surviving patients have been treated with combined parotidectomy and radiotherapy. The authors recently experienced a case of salivary duct carcinoma in right parotid gland which was treated with total parotidectomy and postoperative radiotherapy and report with review of literature.
