A young woman with persistent sore throat, Epstein–Barr virus, lymphadenopathy, and aberrant CD4 + CD7‐ T‐cells

A young woman with persistent EBV viremia and lymphocytosis had an abnormal CD4- T cell population with aberrant loss of CD7. She had a diagnosis of chronic active EBV (CAEBV), a lymphoproliferative disorder for which she ultimately required allogeneic hematopoietic stem cell transplantation.
