• To discuss current and future therapeutic approaches for LCH.

Main Methods:

• Literature review of publications from the Histiocyte Society and related research.
• Analysis of the development of diagnostic criteria and risk stratification.
• Examination of the progression of treatment regimens from historical to experimental.

Main Results:

• Established diagnostic criteria in the 1980s enabled international treatment trials.
• Risk group stratification improved patient outcomes and salvage therapy development.
• Ongoing research is exploring novel experimental therapies for LCH.

Conclusions:

• The conceptualization of LCH pathogenesis directly influences treatment evolution.
• Collaborative efforts and standardized criteria are crucial for therapeutic advancement.
