Inflammatory Pseudotumor of the Spleen in a 6-Year-Old Child: A Clinicopathologic Study

Abstract

Abstract Inflammatory pseudotumors of the spleen are extremely rare in children. To our knowledge, only 3 cases of splenic inflammatory pseudotumors have been reported. An inflammatory pseudotumor of the spleen was found incidentally during the workup of vesicoureteral reflux disease in a 6-year-old girl. The clinical, pathologic, immunophenotypic, and molecular features and the differential diagnostic features are discussed here. Splenic inflammatory pseudotumors, although rare, should be considered in the differential diagnosis of a mass lesion of the spleen in children.
