Parosteal lipoma of the rib: a case report

Lipoma parosteal de arco costal: relato de caso

Celso Montenegro Turtelli, Pedro Paulo Saad Costa, Helder de Souza Lima e Silva



ABSTRACT

The authors report a case of a patient with a progressive-growing mass in the left subaxillary region, since childhood. Chest x-ray and computed tomography showed a well-defined low attenuation mass with irregular calcifications contiguous with the left fifth rib. Histological findings were consistent with parosteal lipoma, a rare slow-growing benign tumor.

Keywords: Parosteal lipoma, Rib, Soft tissue tumor
