Methods: A comprehensive documentation of the clinical features and histological diagnosis was presented
Results: Polymorphous low grade adenocarcinoma is a rare tumour that affects mainly minor salivary glands. The lower lip is not a common site for its occurrence. The tumour has a low potential for metastasis, although spread to regional lymph nodes has been reported, no associated metastasis has been previously documented.
Conclusion: we report a case of PLGA occurring in the lower lip with suspected lung metastasis.
