Inflammatory pseudotumor of the spleen: a case report and review of the literature

Inflammatory pseudotumor of the spleen is a benign tumorous lesion of unkno wn etiology and pathogenesis that has been described in only a few cases in the literature. Recognition of this rare entity is important, as the clini cal manifestations and imaging features could be indistinguishable from a l ymphoproliferative disorder or another malignancy of the spleen. We report a new case and review the clinical presentation, laboratory findings, patho logical and immunohistochemical studies, treatment, and prognosis of the pr eviously reported cases of inflammatory pseudotumor of the spleen.
