ABSTRACT

Mediastinal neoplasms of mesenchymal origin are rare, accounting for less than 6% of these tumors. Most of these tumors are liposarcomas, although cystic lesions are uncommon. The authors present a case of a 58-year-old woman with progressively worsening dyspnea since she was 52-years-old. Laryngeal stridor was auscultable and a chest CT scan showed a cystic lesion in the posterior mediastinum. The tumor was resected and the histological examination revealed myxoid liposarcoma.

RESUMO

As neoplasias mediastinais de origem mesenquimal são raras, representando menos de 6% dos casos. A maioria são lipossarcomas, apesar da aparência cística ser incomum. Os autores apresentam um caso de paciente feminina com 58 anos de idade, com queixa de dispnéia, com piora progressiva desde os 52 anos. Estridor laríngeo era auscultado durante o exame físico, e a tomografia computadorizada de tórax demonstrou uma lesão cística no mediastino posterior. O tumor foi ressecado e o estudo histológico definiu o diagnóstico de lipossarcoma mixóide.
