Primary retroperitoneal extraskeletal mesenchymal chondrosarcoma involving the vena cava: A case report

Abstract

The current study presents a case of extraskeletal mesenchymal chondrosarcoma (ESMC) involving the vena cava that originally occurred in the retroperitoneum of a 61-year-old female. Following excision of the masses, pathological examination confirmed a diagnosis of primary ESMC. Mesenchymal chondrosarcomas are extremely rare in comparison to conventional chondrosarcomas and even more so when arising in an extraskeletal location. In the current report, the major characteristics of ESMC are discussed and a review of the current knowledge regarding this rare disease entity is presented.
