A well-differentiated giant liposarcoma originating from the buccal fat pad

Abstract

Although liposarcoma is one of the most common soft-tissue sarcomas, facial localization is extremely rare, The buccal fat pad is an important anatomic structure located in the face that recently gained interest as a result of increasing research on facial anatomy, In this paper, we report a case of giant liposarcoma originating from the buccal fat pad, The precise localization of the tumor was determined preoperatively with computed tomography examination. The liposarcoma that invaded the body and the extensions of the buccal fat pad was resected completely, The pathological examination revealed a sclerosing, well-differentiated liposarcoma, which is known to be very rare in the head and neck region, Chemotherapy and radiotherapy were not necessary because of the favorable histological type of the tumor and the advanced age and poor general condition of the patient, Local recurrence and distant metastasis were not observed during the 1-year follow-up.
