Diagnosis and management of retroperitoneal mucinous adenocarcinoma possibly originating from previously operated appendix: A rare case

Abstract

Retroperitoneal mucinous adenocarcinoma [RPMA] is a rare condition usually diagnosed incidentally, after surgery. The study reports a case of incidentally diagnosed retroperitoneal mucinous adenocarcinoma in a 78-year-old male. The retroperitoneal cystic mass was resected by careful dissection from the surrounding structures and samples from the cyst and cystic fluid were sent for histopathological evaluation. The histopathological examination suggested a mucinous adenocarcinoma possibly arising from the previously operated appendix. Following the surgery, the patient was stable, however, he suffered a fatal cardiac arrest on day 9 post-operatively. The patient could not be revived despite cardiopulmonary resuscitation.
