Objective: Langerhans cell histiocytosis (LCH) stands as the most common histiocytic disorder. It is categorized into single-system single site, single-system multi-site, and multisystem types, with or without involvement of risk organs. Clinical presentation exhibits considerable variability, contingent upon the affected organ systems. Given its rarity, diverse locations, and varying severity, there are currently no established treatment guidelines for LCH. Case Presentation: We documented the case of a 5-month-old male diagnosed with Langerhans cell histiocytosis (LCH), presenting with high-risk multisystem organ involvement and concurrent unifocal bone involvement. Bone marrow aspiration revealed infiltration by multinucleated giant cells within the marrow. Skin biopsy demonstrated Langerhans cell proliferation with epidermotrophism and the characteristic reniform nucleus resembling a coffee bean. The patient was treated following the histiocytosis protocol, which included daily oral prednisone and 6-mercaptopurine, in addition to weekly intravenous vinblastine and methotrexate administered every two weeks. Unfortunately, the patient displayed limited response during the initial phase of treatment and, tragically, passed away during the eighth week of therapy. Conclusion: Langerhans cell histiocytosis (LCH) is a rare disease characterized by variable disease presentations and is associated with significant morbidity and mortality. Timely recognition of clinical manifestations and risk factors, coupled with appropriate treatment, is crucial to reduce mortality and long-term complications associated with the condition.
