Detection of Epstein–Barr virus in inflammatory pseudotumour of the spleen: a case report

Background: Various types of benign and malignant splenic tumours including hemangiomas, lymphagiomas, hamartomas, hemangiosarcomas, malignant lymphomas and metastatic carcinomas share radiological characteristics making it impossible for a physician to determine the definite aetiology of splenic masses noninvasively without histopathological evaluation. It is important that physicians recognize the importance of a careful and continuous follow-up since inflammatory pseudotumours (IPT) are considered to be tumours with an intermediate malignant potential based on their behaviour when they arise in other locations.

Methods: Our patient, a 60-year-old woman was evaluated using laboratory, gastroscopy, computed tomography and surgical methods. The resected tumour was evaluated using immunohistochemical methods.

Results: The patient presented with weight loss, nausea and vomiting, symptoms lasting over a course of a few months. The splenic mass was found incidentally at the time of work up for gastritis and cholelithiasis. Histologically, the tumour differed from typical splenic architecture being composed of atypical spindle cells with inflammatory elements; numerous plasma cells, macrophages, eosinophils and lymphocytes.

Conclusions: Although very difficult to diagnose at initial presentation, it is very important for the physician to be aware of the importance of a careful diagnosis since IPT of the spleen are rare and considered to be tumours with an intermediate malignant potential
