GUERRERO, José F. et al. Well-differentiated primary pleural liposarcoma. Rev. med. Hosp. Gen. Méx. [online]. 2025, vol.88, n.3, pp.168-172.  Epub 26-Set-2025. ISSN 2524-177X.  https://doi.org/10.24875/hgmx.24000034.

Primary pleural liposarcoma is a rare, slow-growing tumor, representing < 10% of pleural tumors, originating from residual remains of primitive mesenchymal tissue. We present the case of a 61-year-old male patient with chest pain and rapidly progressive dyspnea, observing in the imaging studies a hypodense tumor in the left hemithorax with Hounsfield units of −30 to −130 fatty tissue range with dimensions of 29.5 × 16.1 × 21.9 cm. Excision surgery together with chemotherapy and radiotherapy is the therapeutic alternative that has reported the greatest benefit in these patients.
