A case of inflammatory pseudotumour of the spleen with EBV infection complicated by idiopathic thrombocytopenic purpura

摘要

Aim — Background Reports of inflammatory pseudotumour (IPT) of the spleen with Epstein-Barr virus (EBV) infection complicated by idiopathic thrombocytopenic purpura (ITP) are very rare. The pathogenesis of this tumour has remained obscure, with most authors agreeing that IPT of the spleen is a non-neoplastic, reactive condition. IPT of the spleen often poses diagnostic difficulty because it forms an infiltrative mass which has clinical, radiological and gross pathologic features that suggest a malignant lymphoma, vascular malformations, but also inflammatory myofibroblastic tumour (IMT) and inflammatory pseudotumour-like follicular dendritic cell tumour (IPT-FDC).
