Dedifferentiated Liposarcoma of Foot - A Case Report

Abstract

Liposarcoma is categorised as a second most common soft tissue sarcoma with a peak incidence between the fourth and sixth decade of life with a slight preponderance towards male gender. Dedifferentiated liposarcoma is a rare sarcoma accounting for only 2% of all soft tissue sarcomas. It is defined as the morphological progression of well-differentiated liposarcoma to a non-adipocytic sarcoma. Here, we present a case of primary dedifferentiated liposarcoma arising in the foot of an 80-year-old female who had presented with swelling over dorsum of foot since 1 year. Patient underwent wide surgical excision for the same followed by postoperative radiotherapy treatment. Liposarcoma is most common in the lower extremities; however, its presentation is rare over foot.
