Abstract:

Well-differentiated liposarcoma (WDLPS) is one of the most common soft tissue sarcomas.Thoracic site is uncommon, accounting for 1% of all cases

INTRODUCTION: Atypical lipomatous tumor/well-differentiated liposarcoma (ALT/WDLPS), synonyms of the same disease entity, indicate a locally, aggressive mesenchymal neoplasm composed entirely or partially of an adipocytic proliferation showing at least focal nuclear atypia in both adipocytes and stromals cells. It occurs most frequently in the deep soft tissues of the proximal extremities (thighs and buttocks) and trunk (back and shoulders).
The retroperitoneum and paratesticular area are also common sites.
Unusual sites include the head and neck region, mediastinum, distal extremities, skin, and dermis [2].
These lesions occur mainly in adults, with higher incidence in the fourth and fifth decades of life.
Well-differentiated liposarcoma usually appears as a painless mass, arising in deep sites such as the retroperitoneum, where it can reach large sizes without giving symptoms.
