A 36-year-old woman admitted for abdominal pain underwent US-guided drainage and ethanol injection under a diagnosis of a huge pancreatic cyst. When the cyst failed to shrink, she was referred to our hospital for further treatment. Computed tomography (CT) showed a multilocular cyst 20 cm in diameter with enhanced nodules and calcification adhering to the pancreatic body and tail. Under a diagnosis of mucinous cystic tumor of the pancreas, we surgically resected the tumor together with the pancreatic body and tail. The tumor was diagnosed histologically as minimally invasive mucinous cystadenocarcinoma with ovarian-like stroma. Mucinous cystic tumor resection after long-term follow-up is rare.
