Primary Myxoid Liposarcoma of the Middle Mediastinum About a Case (Primary Myxoid Liposarcoma of the Middle Mediastinum)

Myxoid liposarcomas "LPS" are rare tumors, especially in their mediastinal location. We report a case of a myxoid liposarcoma of the middle mediastinum, in a 51-year-old patient, with no particular pathological history, admitted with a NYHA stage V dyspnea picture. A chest X-ray made objectifying a mediastinal widening of water density, with external edges convex towards the lung and internal edges merged with the mediastinum, the chest CT scan of which links it to a lesion process of the middle mediastinum well defined with clear heterogeneous contours of mixed tissue, fat and water density without calcifications, The punctureCT-guided transparietal biopsy with the result of an anatomopathological study is compatible with a myxoid liposarcoma. Myxoid LPS of the mediastinum is a very rare entity and a few sporadic cases have been reported in the literature. Surgery appears to be the treatment of choice. Radiotherapy and chemotherapy retain their place in very specific indications.
