Abstract

Pleomorphic liposarcoma, which is the rarest of the four liposarcoma types according to the World Health Organization (WHO) classification of soft tissue tumors, is associated with a high rate of recurrence and poor prognosis. In the present report, we present the case of a 69-year-old male patient with pleomorphic liposarcoma arising in the right cheek. The mass was initially considered as benign such as schwannoma due to the absence of facial nerve palsy. However, the mass grew rapidly, requiring surgical removal with facial nerve preservation. Pathological and molecular examination led to the definitive diagnosis of pleomorphic liposarcoma. The postoperative adjuvant radiotherapy was added, and there were no signs of recurrence at four-year follow-up.
