“…Colloid carcinoma demonstrated an improved 5-year overall survival rate of 40–60% compared with tubular carcinomas, which behave similarly to pancreatic ductal adenocarcinoma with a 5-year overall survival rate of 10–20% [ 13 , 14 ]. A previous case report showed that patients with calcification in IPMN who underwent surgical resection had a favorable postoperative prognosis over the 40-month follow-up period [ 5 ]. Similarly, in the present case, the patient underwent pancreaticoduodenectomy and regional lymph node dissection.…”

“…Therefore, pancreatic calcification with IPMN is an exceedingly rare clinical entity that shows no sign of systemic chronic pancreatitis [ 2 , 3 ]. Only a few reports on calcification associated with IPMN have been reported in the literature [ 4 , 5 ]. Therefore, its biological behavior, appropriate treatment modalities, and overall patient prognosis remain largely unclear.…”

Background Colloid carcinoma derived from intraductal papillary mucinous neoplasm (IPMN) of the pancreatic head with prominent calcification is exceedingly rare. Only a few studies about this entity have been reported in the literature. Therefore, its biological behavior, appropriate treatment modalities, and overall patient prognosis remain largely unclear. In this report, we present a case of a resected colloid carcinoma derived from IPMN with prominent calcification. In addition, we review the relevant literature and discuss the clinical management of colloid carcinoma derived from IPMN with prominent calcification, including the histopathological features. Case presentation A 75-year-old man presented with a pancreatic tumor measuring 58 mm on the head of the pancreas that was incidentally detected by abdominal ultrasonography. Abdominal computed tomography and endosonography revealed a multilobular cystic lesion with a 17 mm mural nodule in the pancreatic head. Furthermore, prominent calcification was observed on part of the cyst wall. Magnetic resonance cholangiopancreatography showed a multilobular cyst in the branch duct lacking communication between the cystic lesion and the main pancreatic duct. Thus, the lesion was diagnosed as intraductal papillary mucinous carcinoma (IPMC) with a preoperative classification of T1N0M0 stage IA according to the 8th Union for International Cancer Control (UICC) guidelines, and the patient underwent conventional pancreatoduodenectomy. The resected specimen was microscopically found to contain colloid carcinoma, probably derived from IPMN. In addition, marked calcification was confirmed in the partition wall of the cystic mass. The postoperative course was uneventful, and no evidence of recurrence or metastasis was observed after 10 months of follow-up. Conclusions We consider that colloid carcinoma derived from IPMN should be differentially diagnosed as a pancreatic multilobular cystic lesion with prominent calcification that shows no sign of systemic chronic pancreatitis.
