Inflammatory pseudotumour of the liver: a diagnostic dilemma.

Inflammatory pseudotumour is a rare, focal, benign inflammatory lesion of the liver parenchyma. It is largely a self-limiting entity and has favorable prognosis; it is thus important to preoperatively distinguish this lesion from malignancy, which it closely imitates. Inflammatory pseudotumour may present variously. We present the case of a 54-year old gentleman who presented with a three-month history of low-grade intermittent fever. Ultrasonography and computed tomography revealed a mass in the left lobe of the liver and the erythrocyte sedimentation rate was raised with coincident hypergammaglobulinaemia. A diagnostic laparotomy with left lateral hepatectomy was performed and histopathological evaluation of the specimen along with special staining and tissue culture revealed an inflammatory pseudotumour. On the second day post-operative the fever subsided and following an uneventful five days the patient was discharged and remains well at one-year follow up with no recurrence or relapse.

Cystic ductal adenocarcinoma of pancreas: an unusual variant.

Cystic lesions of the pancreas are usually pseudocysts (90%); only 10% of them are cystic tumors. These cystic tumors constitute less than 10% of all pancreatic neoplasms, making them an extremely uncommon type of pancreatic malignancy. What is more important is that these tumors are very easily misdiagnosed as pseudocysts because their characteristics are very similar to those of the benign pseudocysts. This gains importance as the cystic tumors have a high cure rate and good prognosis if diagnosed and treated on time. Of all the cystic tumors, the most common are the benign serous cystadenomas, mucinous cystic tumors, intraductal papillary mucinous neoplasms etc. Ductal adenocarcinoma of pancreas presenting in cystic form is an uncommon type of cystic tumor, making it extremely rare among all pancreatic malignancies (solid or cystic). We present the following case report. The review of literature concerning the diagnosis and management has also been discussed.
