Inflammatory pseudotumor of the spleen: A rare case diagnosed on FNAC

Abstract: 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.

“…Two cases of splenic IPT with FNAC findings have been reported previously and showed bland‐looking spindle cell clusters with histiocytes and inflammatory cells . Cytological findings of IPT of other organs, such as the liver and lung, have also been described and, as in our case, showed spindle cells, isolated and in clusters, with mixed inflammatory cells and histiocytes.…”

“…The pathogenesis of splenic IPT is not clearly known, but most authors agree that it is a non‐neoplastic and reactive condition, and should be distinguished from the truly neoplastic inflammatory myofibroblastic tumour, which has similar histology. Inflammatory myofibroblastic tumour can be confirmed by ALK‐1 expression in immunohistochemistry or in cytogenetic study . In our case, ALK‐1 was negative, favouring IPT.…”

“…It is formed on the basis of irregular proliferation of inflammatory cells [2] . Generally these tumors have benign behavior with spontaneous regression, but occasionally they have been reported to recur, metastasize and undergo sarcomatous transformation [4] . The clinical symptoms are diverse in nature, with some patients complaining of left flank or abdominal pain, with or without fever and splenomegaly [8] .…”
