Swelling on the Hard Palate Presenting as Polymorphous Low Grade Adenocarcinoma: A Case Report and Review of Literature

Abstract

Polymorphous Low Grade Adenocarcinoma (PLGA) is a relatively newer entity under the sub-classification of adenocarcinoma, which arises mainly from the minor salivary glands. PLGA is difficult to diagnose both clinically and histopathologically due to its indolent presentation and its morphological diversity that includes several microscopic patterns. It is an uncommon malignant neoplasm with low aggressiveness accounting for about 2% of all salivary gland tumours. We are reporting this case of PLGA which arose from the minor salivary gland over the hard palate.
