Abstract
In middle-aged women mucinous cystic neoplasm (MCN) of the pancreas can occur in the body or tail of the pancreas. We report a rare case of mucinous cystadenocarcinoma (MCC) located in the head of the pancreas identified in a 77-year-old woman. The patient was admitted due to right subcostal pain and fever. MCN was strongly suspected due to the presence of an encapsulated, multilocular, cystic tumor with a diameter of 11 cm located in the head of the pancreas on CT. Multiple mural nodules were seen on MRI. Thus, MCC was strongly suspected. A subtotal stomach-preserving pancreaticoduodenectomy (D2 lymphadenectomy) was performed. Ovarian-type stroma and non-invasive adenocarcinoma were evident in the resected specimen on pathology. Thus, the final diagnosis was MCC. It is accepted that complete resection of the tumor is necessary to achieve a cure in non-invasive MCC patients. However, what constitutes an adequate lymphadenectomy is still controversial.
