Inflammatory pseudotumor (IPT) is a rare space-occupying lesion of unknown etiology that can mimic malignancy on clinic-radiological and pathological examination. We present a case of IPT of the spleen which was clinically suspected to be malignant. This case was initially suggested accurately on fine needle aspiration (FNA) of the mass and subsequently confirmed on histopathology of the resected specimen. Diagn.
