Twinning of Pleomorphic Adenoma: A Case Report.

Pleomorphic adenoma is a common benign salivary gland tumor which presents as a painless swelling that gradually increases in size, if left untreated. It is often seen involving the parotid gland. However, pleomorphic adenoma has been reported to involve the minor salivary glands as well. In this report, we present two cases of pleomorphic adenoma originating from minor salivary glands of the upper lip, occurring in two male patients of the same age (44 years) with markedly similar history of duration, size, and site of the lesion. The tumor was excised in both patients and sent for histopathological analysis which showed features of pleomorphic adenoma confirming the diagnosis.
