ABSTRACT Pleomorphic adenoma (PA) is the most common benign tumour of the salivary glands, typically arising in the parotid gland. Only 10% of cases arise in minor salivary glands, with the palate being the most affected site. However, PA in buccal or labial mucosa is a rare occurrence. We report two cases, one of a 31-year-old female who presented with a painless, firm, submucosal nodule on the left buccal mucosa and another of a 44-year-old female who presented with a similar swelling but in the upper labial mucosa. Both cases were later diagnosed with PA on histopathology. Through these case reports, we highlight the importance of considering salivary gland tumour in innocuous mucosal masses as well as the crucial role of histopathology in the diagnosis of the lesion for timely intervention.
