Adenomatoid hyperplasia (AH) is an uncommon, non-neoplastic swelling on the palate caused due to hyperplasia of the mucinous acini. The lesion clinically presents as a sessile tumor-like nodule resembling pleomorphic adenoma. Histopathologic findings include lobules of enlarged mucinous acini which are filled with secretory granules. The nuclei are squeezed to the basal portions, associated with focal inflammation and ductal dilatation, and a history of trauma is often elicited. Here, we report a rare case of AH of the lower lip in a 20-year-old male patient, which mimics a mucous retention cyst or mucocele.
