Salivary duct carcinoma of the minor salivary gland in hard palate

In 1968, Kleinsasser et al described the 5 cases of salivary duct carcinoma as a specific diagnostic category of salivary gland adenocarcinoma. Salivary ductal carcinoma is uncommon salivary gland neoplasm which has a characteristic morphologic pattern, intraductal and infiltrating papillary carcinoma, comedonecrosis, and infiltrating ductal carcinoma with reactive fibrosis. This disease occurs predominantly in male, in sixth and seventh decade and in parotid gland. We first experienced a 64-year old man with salivary duct carcinoma of the minor salivary gland in hard palate. So in this paper, we describe the clincopathologic findings, treatment, and clinical course in the patient.
