This report presents two cases of solid and cytic tumor (SCT) of the pancreas, and discusses the indications for surgical treatment on the basis of 126 cases discribed about macro- and microscopical observations among SCT cases reported in Japan. Case 1 was a 23-year-old woman who complained of abdominal mass. An encapsulated cystic tumor (11×7 cm in size) was detected at the pancreatic tail, and distal pancreatectomy was performed. Case 2 was a 44-year-old woman in whom a cystic tumor (5×4 cm in size) with calcification in the capsule was detected at the pancreatic body. This patient also underwent distal pancreatectomy. Histologically, both tumors were confirmed to be SCT. In the review of 126 cases of SCT including our 2 cases, metastasis to a regional lymphonode was observed in only one case, and post operative metastasis or recurrence were found in 3 cases. The characteristic patterns of metastasis and/or recurrence were hepatic metastasis, but there was no metastasis to a lymphonode. There were 2 dead cases, all over 60 years of age, and the causes of death were related to hepatic metastasis. Therefore, it was suggested that the early detection of hepatic metastasis is most important in order to obtain better results. Further analysis will be necessary to assess the significance of the relationship between surgical treatment and metastasis to lymph node.
