  • Abstract
  • Look Inside

 Three patients with small cystic tumor of the pancreas were described (Table 1). They had upper abdominal pain as their symptom. Physical findings and laboratory values were normal except for glucose tolerance test. Endoscopic retrograde pancreatography (ERP) played a crucial role for diagnosis, showing a small cystic formation communicating with the main pancreatic duct. Linear filling defects seen in the main pancreatic duct seemed to be due to mucin produced by the tumor (Figs.1, 2, 6, 8). These findings are similar to those of mucin-producing pancreatic cancer, which has recently drawn attention because of the characteristic, macroscopic and pathological findings as well as the favourable prognosis. By histology, however, the lesions in these patients were mucinous cystadenoma (case 1, 2) and retention cyst (case 3) lined by epithelium with cytoplasm containing abundant mucin. The similarity of the ERP and microscopic fiindings between these lesions and mucinproducing carcinoma, are of interest, because of the possible etiologic relationship which may exist between them.
