Polymorphous low grade adenocarcinoma (PLGA) is a rare, low-grade malignancy of minor salivary glands accounting for 2% of salivary gland tumours. The most common sites are palate (60%), lip, buccal mucosa, alveolar ridge and base of the tongue with retromolar region being very rare (0.5%). It is considered to be a low grade malignancy with indolent nature. Very few cases with metastatic spread to lymph nodes and lung have been reported in literature. This report of PLGA is a rare case presenting in an uncommon location (retromolar area) with suspected lymph node and lung metastases.
