Primary mucinous cystadenocarcinoma of the pelvic retroperitoneum in a male

Abstract

Primary mucinous cystadenocarcinoma of the retroperitoneum is an extremely rare malignancy with only 2 male patients reported in the literature. We describe an unusual case presenting as a pelvic mass in a male with previous pan-proctocolectomy and end ileostomy for Crohn's disease and review the available literature.
