Unusual salivary glands adenocarcinomas: a retrospective study.

Abstract

Malignant tumors of the salivary gland ducts exhibit variable morphological patterns and biological behavior. This group of neoplasms includes some uncommon lesions that originate from the intercalated ducts, such as polymorphous low-grade adenocarcinoma, epithelial-myoepithelial carcinoma and basal cell adenocarcinoma, and other that arise from the excretory duct, such as the salivary duct carcinoma. One hundred and seventy-seven malignant neoplasms of the major and minor salivary glands were reviewed. There were 23 cases of uncommon types of ductal carcinomas. Age, sex, location, size of tumor were examined as well as their histopathological features. There were four polymorphous low-grade adenocarcinomas (17.3%), two of which were located on the palate and two on the cheek; seven epithelial-myoepithelial carcinomas (30.4%), most of them located in the parotid; six basal cell adenocarcinomas (26%) which predominated in the submandibular gland, and there were six salivary duct carcinomas (26%), four of which occurred in the parotid gland, and two in the submandibular gland.
