Soft Tissue Tumours of the Retroperitoneum

摘要: Purpose. This review summarizes the more prevalent soft tissue tumours arising in retroperitoneum and highlights some recent fundamental diagnostic developments relevant to mesenchymal tumours. Discussion. The is an underestimated site for benign malignant neoplastic disease, represents second most common of origin primary (sarcomas) after deep tissues lower extremity. In contrast predominance lesions over sarcomas elsewhere, retroperitoneal are far likely be malignant. differential diagnosis primarily with lymphoproliferative parenchymatous epithelial this area, metastatic disease from known or unknown sites elsewhere.The at a lipomatous, myogenic neural nature.Their generally late clinical presentation poorly accessible location provides numerous challenges; optimal radiological imaging properly performed biopsy essential cogs management route. Histopathological may complicated, but has been aided by fields immunohistochemistry tumour (cyto)genetics. Despite significant advances oncological protocols, prognosis remains less favourable than similar sites.
