PRIMARY MUCINOUS CYSTADENOCARCINOMA OF THE RETROPERITONEUM - REPORT OF A CASE AND LITERATURE-REVIEW

Primary retroperitoneal mucinous cystadenocarcinoma (PRMC) is a tare t umour, similar to its ovarian counterpart but without any evidence of ovarian, pancreatic or another extra-retroperitoneal origin. Histogene sis of this neoplasm remains uncertain, Mucinous or coelomic metaplasi a of retroperitoneal mesothelium has been recently proposed as its ori gin, In a 43-year-old woman with a 15-cm cystic lesion in the right re troperitoneum mucinous cystadenocarcinoma was diagnosed, and no primar y tumour was identified. Two peritoneal endometriotic foci were found on further surgery. We suggest a common histogenesis for PRMC and thes e en dometriotic foci.
