Histiocytosis Program

The Histiocytosis Program at Children’s Hospital and Vanderbilt University Medical Center offers comprehensive diagnostic, consultative and therapeutic services for children and adults with Langerhans cell histiocytosis (LCH; also known as eosinophilic granuloma or histiocytosis X), hemophagocytic lymphohistiocytosis (HLH), Rosai-Dorfman disease (RDD; also known as sinus histiocytosis with massive lymphadenopathy), juvenile xanthogranuloma (JXG), and other less common histiocytic disorders.

Histiocytosis is a rare blood disease that affects 1 in 200,000 children born each year in the United States. It is caused by an excess of white blood cells called histiocytes. The histiocytes cluster together and can attack the skin, bones, lung, liver, spleen, gums, ears, eyes, and/or the central nervous system. The disease can range from limited involvement that spontaneously goes into remission without treatment to progressive multi-organ involvement that can be chronic and debilitating. In some cases, the disease can be life-threatening.

In some ways, histiocytosis is similar to cancer and has historically been treated by oncologists with chemotherapy and radiation. The vast majority of people diagnosed with histiocytosis are children under the age of 10, but it is also found in adults of all ages.
