Secondary Immune Thrombocytopenic Purpura Due to Primary Epstein- Barr Virus Infection.

A rare complication of infectious mononucleosis is immune thrombocytopenic purpura (ITP). The majority of people affected by Epstein-Barr Virus (EBV) are below the age of 30, while ITP is usually seen with peaks of incidence in the elderly and children. The unique case of an otherwise healthy 22-year-old female will be discussed, with an initial presentation of ecchymosis, rash, and epistaxis, and was subsequently found to have severe thrombocytopenia. The diagnosis of primary EBV infection due to EBV was eventually made, responsive to intravenous (IV) Methylprednisolone. It is important to consider primary EBV infection in the differential diagnosis of a patient who presents with acute thrombocytopenia.
