The differential diagnosis of IPMN and MCN is very important for clinicians. MCN is reported to develop in middle-aged females (mean age 48 years) and in the body and tail of the pancreas. Some doctors insist that ovarian-like stroma is absolutely necessary for the definition of MCN. Prompt resection of MCN after diagnosis is desirable. In contrast, about 60% of cases with branch-type IPMN do not require an operation. Therefore, one of the important goals in the differential diagnosis of MCN and branch-type IPMN is to determine the surgical indications before the operation. We believe that MCN and IPMN should be defined by imaging procedures before the operation. We suggest that a neoplasm with an appearance similar to an orange should be diagnosed as MCN, while that with an appearance similar to a bunch of grapes in MRCP should be diagnosed as branch-type IPMN. Proposal of a new concept: If the term MCN is restricted to neoplasms that exhibit ovarian-like stroma, we propose that lesions which are surrounded by a very thick capsule, and which show an orange-like appearance by imaging procedures without histological ovarian-like stroma should be called MRN (mucinous round neoplasm) or MSN (mucinous spherical neoplasm).
