摘要

We present the case of a 3-year-old boy of white non-consanguineous parents who was referred with a history of fever, unexplained (hepato)splenomegaly, and lymphadenopathy after unexplained pneumonia. Results of microbiological tests, including serology and PCR, were negative for more than 20 viruses, including EB V, cytomegalo virus, adenovirus, parvovirus, and human herpesvirus 8.
