Since 1932,a total of 138 cases of pancreatic cystadenoma including our own case has been reported in the Japanese literature : thirty-one males with an average age of 61.5 years and 105 females with an average age of 42.8 years were noted. The prevalent ages were in more than the 40s in males, and in the 20 40s and more than the 60s in females. Among them, 19 cases of microcystic adenoma, being usually benign, with the male-to-female ratio of 1 : 1.8,average age of 60.4 years and frequent occurrence in the pancreatic head and 38 cases of macrocystic adenoma, having a malignant potential, with the male-to-female ratio of 1 : 6.4,an average age of 45.2 years and frequent occurrence in the pancreatic body and tail, were demonstrated. Signs and symptoms of the patients and the average in largest diameter of the resected specimens showed no significant difference between the two types of cystadenoma. A total of 161 cases of pancreatic cystadenocarcinoma in Japan was also reviewed and compared with these cystadenomas. Although operative strategy for pancreatic cystadenoma mainly depends on the location of tumor, a complete removal is preferred : operative mortality is 1.8% in the Japanese cases. So-called drainage operation is ineffective for the neoplastic pancreatic cysts and is contraindicated for macrocystic adenoma because of the threat of developing cystadenocarcinoma. Thus, to avoid inadequate surgery for pancreatic cystadenoma, thorough assessments of preoperative imaging modalities and immediate histological evaluation of intraoperative specimens are mandatory.
