Abstract
Serous cystadenoma of the pancreas is a slow-growing benign tumor. Although it may become symptomatic following tumor growth, jaundice due to biliary obstruction is rare even in cases with tumors of the head of the pancreas. A 31-year-old woman who had pancreatic tumor was referred to our hospital. She was given a diagnosis of serous cystadenoma, 30 mm in diameter, by imaging studies and followed-up because she was asymptomatic. During 8 years of follow-up, the tumor had gradually increased from 30 to 43 mm in size, and the patient had obstructive jaundice. She underwent pancreaticoduodenectomy. Pathological examination of the resected specimen showed serous cystadenoma of the pancreas, of which a part compressed the bile duct. The growth rate of the present case was 1.3 mm/year and the doubling time was 23.1 years, which presented a relatively slow growing rate even among patients with serous cystadenoma of the pancreas with obstructive jaundice.
