title: Polymorphous low grade adenocarcinoma: literature review and report of lower lip lesion with suspected lung metastasis.
abstract: Polymorphous low grade adenocarcinoma (PLGA) is an uncommon tumour that affects minor salivary glands mainly. It was known to be clinically benign and histologically polymorphic; sometimes misdiagnosed as pleomorphic adenomas, monomorphic adenomas, malignant pleomorphic adenomas, adenoid cystic carcinomas and adenocarcinoma not otherwise specified. More information about PLGA is cumulating in the current literature with new evidences suggesting that the tumour may not be as indolent as it was previously thought. A thorough understanding of the clinical and histological behaviour of the lesion has serious implications in management. Here, a case of lower lip lesion with suspected lung metastasis is reported to exemplify how the clinical behaviour of the lesion may affect management.
