What We Do

The Histiocytosis Association is a global nonprofit organization dedicated to addressing the unique needs of patients and families dealing with the effects of histiocytic disorders while leading the search for a cure.

Fund Research

$7 million in total research funded that is resulting in fewer patient fatalities and more effective treatments.

Provide Information & Resources

to 19,500+ physicians, patients, families and friends since the organization began in 1986.

Community Outreach

We connect patients and families through meetings and events, and connect physicians through the Histiocyte Society.

Support Clinical Trials

We promote new and emerging treatments through the funding of clinical trials and studies.

“I naturally gravitated to the literature and sought out resources, including the Histiocytosis Association in order to learn more about why LCH occurs, who is impacted, what are the protocols for treating various systems (e.g. bones, GI, skin). In my search for knowledge, I learned that LCH is still not well understood and often cast aside as a “non-cancer” despite being labeled as a histiocytic neoplasm by the National Comprehensive Cancer Network and blood cancer by the World Health Organization.”

– Andrea, a Histio Mom & Ambassador
