AIM: To compare the clinico-pathological features of intraductal papillary mucinous cystic tumours (IPMT) and mucinous cystic tumours (MCT) of the pancreas. METHODS: Eighteen patients with IPMT and 18 with MCT who underwent surgical resection between 1990 and 2004 were retrospectively reviewed. Their clinico-pathological features were compared using univariate analysis. Statistical analyses of potential predictive factors of malignancy for each of these two groups were also conducted. RESULTS: Patients with IPMT were found to be older (64+/-10 vs 43+/-18 years, p<0.001) and were predominantly male (male:female ratio, 5:4 vs 1:17, p=0.003) as compared to patients with MCT. MCTs were found in the body-tail region (100%) whereas IPMTs were more evenly distributed (50% in the head) (p=0.001). Pathologically, IPMT was distinct from MCT in terms of size (3.8+/-3.2 vs 9.1+/-4.4 cm, p=0.001), association with secondary pancreatitis (50 vs 0%, p=0.011), communication with the pancreatic duct (94 vs 0%, p<0.001), presence of a dilated main pancreatic duct (61 vs 0%, p<0.001) and the presence of ovarian-type stroma (0 vs 44%, p=0.003). CONCLUSION: IPMT and MCT are distinct clinico-pathological entities. This distinction is important as management and outcome of these entities may differ.
