Background: Pleomorphic adenoma (PA) is a benign tumor most common in major salivary glands. PA of pterygomaxillary space (PMS) is rare. Only one case of PA arising from the pterygopalatine fossa (PPF) was reported. We are presenting a second case, its presentation and surgical management, which is different and less morbid from the recently described reports. Case description: A 40-year-old female presented with ill-defined right cheek swelling for the last 5 years. On evaluation, there was a firm mass in the PMS, which was diagnosed as PA. Surgical excision was planned with sublabial incision combined with lip split, which could entirely reach, delineate, and remove the tumor in toto. The patient has recovered well and was discharged on the 3rd day. Conclusions: Pleomorphic adenomas of PMS present late due to their anatomical location and indolent course. Contrast-enhanced computed tomography scan is an important diagnostic tool. Fine-needle aspiration cytology from the buccal aspect reveals the probable histopathology. Sublabial incision with lip split is more useful in excising the moderate-sized tumors.
