OLIVEIRA, Michelle Lucinda Gonçalves de and LOPES FILHO, Gaspar de Jesus. Primary retroperitoneal neurofibrosarcoma. Rev. Col. Bras. Cir. [online]. 2003, vol.30, n.5, pp.399-401. ISSN 0100-6991. http://dx.doi.org/10.1590/S0100-69912003000500013.
Malignant schwannoma or neurofibrosarcoma usually grows from the peripheral nerves and rarely from the retroperitoneum. When found in the retroperitoneum, it usually has a worse prognosis. This kind of tumor seems to be resistant to adjuvant therapy and the best treatment is radical surgery. We report a case of a primary retroperitoneal malignant schwannoma, in a 64 year-old man, treated surgically.
