Classification and external resources

Salivary duct carcinoma, abbreviated SDC, is a rare type of aggressive cancer that arises from the salivary glands.[1] It is predominantly seen in men and, generally, has a poor prognosis.[2]


The typical presentation is a rapidly growing mass with associated pain.[2] This may be seen in association with neck lymph node swelling (cervical lymphadenopathy), due to metastases, and facial nerve paralysis.


SDC are diagnosed by examination of tissue, e.g. a biopsy.

Their histologic appearance is similar to ductal breast carcinoma.
