Parotid cribriform salivary carcinoma of the excretory ducts.

Abstract

Parotid cribriform salivary carcinoma of the excretory ducts (CSCED) is an unusual parotid neoplasm with very distinctive histological features. It is a highly malignant tumor with a grave prognosis, CSCED is often misdiagnosed, since it is uncommon and difficult to distinguish from metastatic adenocarcinomas. The neoplasm most often occurs in the parotid gland of middle-aged or older males and has the most dismal prognosis of all salivary carcinomas. Little information is available in the literature as to the management of this rare tumor. The diagnostic features of CSCED are discussed, along with the case management of a 46-year-old female patient who was treated and remains tumor free after 5 years.
