title: [A case of splenic inflammatory pseudotumor].
abstract: A 74-year-old woman underwent abdominal echography at a local clinic and a splenic mass was found. She was hospitalized for detailed examinations and treatment. Splenectomy was performed to make a definite diagnosis and for treatment because a definitive diagnosis could not be made, despite various examinations. Histopathological examination revealed that the lesion was infiltrated by polyclonal lymphoid cells and contained proliferating spindle-shaped fibroblasts without any atypical cells, so the splenic mass was diagnosed as an inflammatory pseudotumor. Because some cases of inflammatory pseudotumor can be diagnosed from the clinical course and imaging findings, this possibility should also be considered in the differential diagnosis of a splenic mass.
