A case of EBV-positive inflammatory pseudotumor-like follicular dendritic cell sarcoma of the spleen with literature review
Inflammatory pseudotumor-like follicular dendritic cell sarcoma(IPT-like FDCS)of the spleen is a rare low-grade malignant tumor disease,mostly associated with Epstein-Barr virus(EBV)infec-tion,and has a high clinical misdiagnosis rate.This paper reports a case of an incidentally detected splenic mass during a physical examination,which was diagnosed as EBV-positive IPT-like FDCS of the spleen through laboratory tests,imaging studies,and pathological examination.Combined with a review of relevant domestic and international literature,this report aims to further clinical understanding of this disease and avoid misdiagnosis.
