AbstractSalivary duct carcinoma (SDC) is a highly malignant tumor that is histologically similar to ductal carcinoma of the breast. This article presents the clinicopathologic features of 15 patients with SDC arising in the salivary glands. The majority of patients were male and aged 65 years or older. The tumor was most often located in the parotid gland. Pain, facial palsy, and presence of calcification in the CT scan were diagnostic features suggestive of SDC. Histologically, 27% of the tumors arose from pre-existing pleomorphic adenoma. Perineural and lymphatic invasion were common findings. There was an extensive cervical lymph node involvement (73%). Distant metastasis was the most common cause of failure. Although SDC exhibits an unpredictable clinical course, total parotidectomy with neck dissection and adjunctive radiation therapy appear to be appropriate for local and regional control of this aggressive neoplasm.
