Abstract
Polymorphous adnenocarcinoma (PAC) is a less aggressive malignant tumour, mainly occurs in the minor salivary glands. It is less frequently seen in the upper lip. As there aren't any specific features to differentiate PAC from other benign tumours of the minor salivary glands of the upper lip, PAC must be considered in the differential diagnosis of the minor salivary gland tumours of the upper lip.
