Inflammatory pseudotumor of the spleen

Abstract

We report a case of a patient with inflammatory pseudotumor (IPT) of the spleen. IPTs can appear at many sites and represent rear lesions of uncertain etiopathogenesis. Usually they present as mass lesions, so the clinical and radiologic features often suggest malignancy. However, the microscopic findings are quite characteristic, and the diagnosis can be made readily by identifying the reactive nature of the cells. Diagnostic problems can arise when these lesions occur in lymphoid organs or the spleen.
