Liposarcomas: Experience of the Oncology and Radiotherapy Department and the Anatomy-Pathology Department at the Mohammed VI University Hospital in Marrakech: 10-Year Retrospective Study from January 2010 to January 2020

Liposarcomas are rare soft tissue tumors that arise from adipose tissue. They account for 1% of all malignancies and 15% to 20% of soft tissue sarcomas. Between January 2010 and January 2020, we reported 21 cases of Liposarcomas detected at the university hospital Mohamed VI of Marrakech's anatomical pathology department. The average age is 50, with a male majority. The average length of consultation was two years. The most revealing indication is tumefaction of the soft tissue. Most of the lesions were concentrated in the lower extremity. The preferred seat for these malignancies is the thigh. The X-ray was used on 21 patients, the echography was used on 16 patients, and the computed tomography was used on 15 patients. There have been 12 cases of magnetic resonance imaging and two cases of Doppler echography for two patients. The well differentiated Liposarcoma is the most common histologic sub-type (52%), followed by myxoid Liposarcoma (28%). 95% of patients had surgery, 90% of which was conservative, and 17 patients were referred for radiation supplementation, with only one instance receiving chemotherapy. In five cases, there was a loco regional recurrence, and one incidence of metastasis was discovered.
