Abstract

Introduction: Chediak-Higashi syndrome (CHS) is caused by dysfunction of lysosomal trafficking and presents with hypopigmentation, bleeding tendencies, neurological symptoms, and NK cell dysfunction. Hemophagocytic lymphohistiocytosis (HLH) can complicate CHS due to the abnormal function of NK cells. Case presentation: This 1.5-year-old light-skinned gray-haired girl microscopically had abnormal hair pigment clumps and lilac inclusions in the myeloid series, characteristic of CHS. She presented with HLH, requiring treatment with etoposide and dexamethasone followed by cyclosporine and dexamethasone. Conclusion: CHS is one of the underlying primary causes of HLH. © 2022 Taylor & Francis Group, LLC.
