摘要
Hemophagocytic lymphohistiocytosis (HLH) is a rare, and potentially fatal, syndrome, characterized by immune system dysregulation, with excessive activation of the macrophages and cytotoxic T cells. It can be classified into primary (genetic) and secondary (acquired) forms. HLH presents with fever, hepatosplenomegaly, cytopenia, and hyperferritinemia, with involvement of various organs. The initial symptoms of HLH are non-specific, but as, if untreated, it can progress rapidly to multiorgan failure, timely diagnosis is essential. We present here two cases of HLH in infants that illustrate the importance of early diagnosis and appropriate treatment, along with a short review of HLH.
