  • Title: Cystic tumours of the pancreas: a diagnostic dilemma.
    Author: Ooi LL, Ho GH, Chew SP, Low CH, Soo KC.
    Journal: Aust N Z J Surg; 1998 Dec; 68(12):844-6. PubMed ID: 9885865.
    Abstract:
    BACKGROUND: Cystic neoplasm of the pancreas is an uncommon entity that encompasses a range of tumours with varying potential for malignancy. These tumours are frequently misdiagnosed as pseudocysts and are inappropriately managed. METHODS: A retrospective review was undertaken of 18 cases of cystic tumours of the pancreas over an 8-year period in two large hospitals in Singapore. RESULTS: All patients were Asian, with a younger age group (mean 43.5 years) and a lesser degree of female predominance (3.5:1 ratio) compared to other series. Pain was the most common symptom. Pre-operative diagnosis using ultrasound and computed tomography was not diagnostic in half of the cases and misdiagnosed as pseudocyst in a sixth. There were five serous cystadenomas, four mucinous cystadenomas, two mucinous cystadenocarcinomas, one mucinous cystadenocarcinoma with cystic degeneration in a ductal adenocarcinoma, three Frantz tumours, one acinar cell tumour, one glucagonoma, and one benign epithelial cyst. Two-thirds of tumours were malignant or had the potential to become malignant. Resection was curative in all cases, and no recurrence was noted at a mean follow-up of 34.5 months. CONCLUSIONS: The difficulties with pre-operative diagnosis, the high incidence of tumours with potential malignancy, and the good outcome with resection, suggest that all suspected cystic tumours of the pancreas should be resected.
