INFLAMMATORY PSEUDOTUMOR OF THE LIVER - REPORT OF 4 CASES AND REVIEW OF THE LITERATURE

Inflammatory pseudotumor of the liver is a benign localized lesion of unknown etiology, frequently misinterpreted as a malignant process by non-invasive diagnostic techniques. Histology shows fibroblasts, histi ocytes and plasma cells within a fibrous framework. We report four cas es of inflammatory pseudotumor of the liver, and compare their feature s with previously reported cases. Inflammatory pseudotumor may be an u nderestimated entity, and because of its self-limiting and favorable c linical course it must not be neglected in the differential diagnosis of a suspect liver mass in order to avoid, when possible, unnecessary surgical resections.
