Liposarcoma is a malignant mesenchymal tumor originating in adipose tissue cells. It occurs mainly in the extremities and retroperitoneum, but is rarely found in the head and neck region, including the oropharanyx. Thus, the objective of the present article is to presented the case report of a 27-year-old woman with a bulge in the soft palate for three years. Imaging exams showed tissue with a density compatible with fatty tissue. The lesion was removed, and the histopathology exam suggested lipoma of the soft palate. The patient missed her check-ups, and the lesion recurred three years after being removed. She again underwent surgery, and histopathology revealed a well-differentiated liposarcoma of the soft palate. Since then, the patient has maintained outpatient follow-up without evidence of recurrence. It can be concluded that, although rare in the head and neck region, liposarcoma should be considered as a possibility for lesions with a lipomatous component.
