A case of a mucin producing cancer of the pancreas with a calcified metastatic lesion in a 76-year-old female is reported. Abdominal radiography showed calcification in the left upper quadrant. Ultrasonography and computed tomography revealed a calcified tumor in the tail of the pancreas and a tumor with calcification in the liver. The findings of endoscopic retrograde pancreatography corresponded to type 3 in our endoscopic retrogracde cholangiopancreatography classification of pancreatic cancer, that is, the condition was diagnosed as filling defects in the dilated main pancreatic duct. The preoperative diagnosis was a mucin producing cancer of the pancreas, liver metastasis and direct invasion of the transverse colon. Resection of the body and tail of the pancreas, splenectomy and partial resection of the transverse colon were performed. Microscopic examination indicated mucinous adenocarcinoma. The mechanism of calcium deposition in this case was believed to be dystrophic calcification. Five cases of mucin producing tumor of the pancreas with calcification were previously reported.
