What is histiocytosis?

Histiocytosis is a general name for a group of syndromes that involve an abnormal increase in the number of immune cells called histiocytes.

There are three major classes of histiocytoses:

  • Langerhans cell histiocytosis, which is also called histiocytosis X
  • Malignant histiocytosis syndrome (now known as T-cell lymphoma)
  • Non-Langerhans cell histiocytosis (also known as hemophagocytic syndrome)

This article focuses only on Langerhans cell histiocytosis (histiocytosis X).

Alternative Names:

Histiocytosis X; Langerhans cell histiocytosis; Eosinophilic granuloma; Pulmonary histiocytosis X; Nonlipid reticuloendotheliosis; Pulmonary Langerhans cell granulomatosis; Hand-Schuller-Christian disease; Letterer-Siwe disease
