Polymorphous low-grade adenocarcinoma of submandibular gland

Introduction: Polymorphous low-grade adenocarcinoma [PLGA] occurs mostly in minor salivary glands, and there are only a few reports of major salivary gland origin

Case Presentation: We herein report a case of de novo PLGA arising in a submandibular gland in an 88 years-old woman. On examination, a large firm and non-tender mass was palpable in the submandibular region

Conclusions: Neither lymphadenopathy nor enlargement of any other salivary glands was present. CT showed a well-defined mass with irregular enhancement in the submandibular gland
