Pseudomyxoma Peritonei Secondary to Rupture of Intraductal Papillary Neoplasm of Pancreas (IPMN)

摘要

Pseudomyxoma peritonei is the intraperitoneal accumulation of a gelatinous ascites secondary to mucinous tumour rupture, more commonly associated with ovarian and appendiceal mucinous tumour. However, pancreatic mucinous tumour, rarely Intraductal Papillary Mucinous Neoplasm (IPMN) is sometimes the aetiological factor. IPMN is either main pancreatic duct, branch duct or mixed duct type and is characterised by abundant extracellular mucin production and mucin retention in the pancreatic duct. This case report highlights the rare occurrence of Pseudomyxoma peritonei secondary to IPMN rupture.
