Histiocytosis X (chronic)

Such abnormalities can predispose the patients with histiocytosis X to the development of bacterial infections, and a similar mechanism may have taken place in this patient.

Langerhans cell histiocytosis (histiocytosis X) was not included in the analyses as this group of diseases is not now regarded as neoplastic.

They are a characteristic microscopic finding in Langerhans cell histiocytosis (Histiocytosis X), which is one of a group of rare conditions collectively known as histiocytosis.

The disease has gone by several names, including Hand-Schüller-Christian disease, Abt-Letterer-Siwe disease, and histiocytosis X, until it was renamed in 1985 by the Histiocyte Society.

Langerhans cell histiocytosis is the terminology currently preferred over histiocytosis X, eosinophilic granuloma, Abt-Letterer-Siwe disease, Hand-Schuller-Christian disease, or diffuse reticuloendotheliosis.

Types of LCH have also been known as "Eosinophilic Granuloma", "Hand-Schuller-Christian Disease", "Letterer-Siwe Disease", and "Histiocytosis X".

For now, the term Langerhans cell histiocytosis remains, although we may be returning to an era of Histiocytosis X until the precise origin of the CD207-positive cells in LCH are fully understood.
