[Polymorphous low-grade adenocarcinoma of the minor salivary glands. A case report and review of the literature].

Abstract

Polymorphous low-grade adenocarcinoma is a distinct type of salivary gland carcinoma arising most often intraorally and primarily in the palate. It is characterized by bland nuclear chromatin, variation in histomorphology and low-grade malignancy. We report a case of this recently described entity in a 66 year old male, presenting most of the characteristic clinical and histologic features. A short review of the current literature concerning this tumor is included.
