Synchronous Parotid and Homolateral Submandibular Gland Pleomorphic Adenoma

Pleomorphic adenomas are benign neoplasms of salivary glands. The simultaneous homolateral occurrence of these tumors in salivary glands is exceedingly rare.

An adult female presenting to our OPD with the swelling of right-sided preauricular and submandibular regions was diagnosed with the pleomorphic adenoma based on fine needle aspiration cytology. The patient was subjected to the excision of both swellings under general anesthesia. Postoperative facial nerve functions were within normal limits and final histopathology confirmed pleomorphic adenoma involving both the sites. A pertinent detailed literature review of English and non-English studies was indicative of only nine such cases.

Simultaneously occurring pleomorphic adenoma involving homolateral parotid and submandibular glands is a rare phenomenon that should be kept in mind when examining the swelling of the unifocal salivary gland.
