A Case of Mucinous Cystadenocarcinoma of the Pancreas Ruptured by Trauma

Abstract

A 44-year-old woman with a chief complaint of pain due to bruising in the upper abdomen visited her local doctor. Intra-abdominal bleeding and intestinal injury were suspected, and she was referred to our hospital. Based on CT findings, acute generalized peritonitis due to pancreatic injury or ruptured pancreatic cyst was suspected, and emergency surgery was performed. The histopathological findings of the partially resected cyst wall revealed a mucinous cystic neoplasm. Eleven days after the initial surgery, pancreaticoduodenectomy was performed. Mucinous cystadenocarcinoma (MCC) was diagnosed from the resected specimen. There is no evidence for a benefit of chemotherapy after radical surgery for ruptured MCC. In our case, S-1 therapy was selected and the patient has been recurrence-free in a short period of observation.
