title: [Primary retroperitoneal tumors].
abstract: We report 14 cases of primary retroperitoneal tumor and one retroperitoneal papillary cystoadenoma in a patient who had undergone hysterectomy and bilateral adnexectomy for uterine myomatosis 15 years before the onset of the clinical features that led to the diagnosis of retroperitoneal tumor. For this reason, we believe this latter case should be included in this series. We consider any tumor mass within the retroperitoneal space (previously described anatomically) to be primary retroperitoneal tumors, regardless of their histology or origin, excluding lymphomas, renal, upper urothelial, adrenal and pancreatic tumors. Although it may often be very destructive and may not significantly improve the prognosis, surgery continues to be the best therapeutic option.
