Secondary hemophagocytic syndrome (HPS) causes various complications such as infectious diseases and malignant tumors. On the other hand, if cytopenia is observed during treatment of bacterial infection, it is difficult to recall the complication of viral infection because drug-inducement and the possibility of treatment failure are considered to be the first diagnosis. This paper reports the case of virus-associated hemophagocytic syndrome (VAHS) that may be caused by parvovirus B19 during the treatment of cervical purulent lymphadenitis by methicillin-resistant Staphylococcus aureus (MRSA). In this case, if blood cell depletion or re-fever is observed during the course of treatment for cervical purulent lymphadenitis, secondary HPS due to viral infection could be a differential diagnosis in addition to exacerbated bacterial infection and druginducement.
