Report of Pancreatic carcinoma coexist with Pancreatic pseudocyst is rare. We have experienced a case of pancreatic carcinoma which was diagnosed and resected by coexisted pancreatic pseudocyst. The patient aged 53 years, complained of epigastric distension and visited our hospital. There was no past history of abdominal injuries and he didn't drink much. A cyst 7cm in diameter was found at pancreatic tail lesion by our examination. By blood chemistry tumor marker CA19.9 was 310 and he complicated diabetes mellitus. We suspected pancreatic carcinoma coexist with pancreatic pseudocyst, so distal pancreatectomy and splenectomy was performed. We found a solid tumor sized about 3cm in diameter at just proximal of pancreatic cyst. Since perioperative histological examination revealed adenocarcinoma, we performed lymph node dissection. The tumor was highly differentiated adenocarcinoma which invaded retroperitoneum in some lesion. The patient died 10 months later by recurrence. We concluded that we must take into account not only laboratory finding but their clinical course in such cases.
