Aspecte clinice ale histiocitozei cu celule Langerhans (histiocitoza X) | [Clinical matters of the Histiocytosis X]

Abstract

Histiocytosis X is a generic term that refers to an increase in the number of histiocytes, a type of white blood cell that act as scavengers to remove foreign material from the blood and tissues. Since recent research demonstrated Langerhan cell involvement as well as histiocytes, this led to a proposal that the term Langerhans Cell Histiocytosis (LCH) be used in place of histiocytosis X. Either term refers to three separate illnesses (listed in order of increasing severity): eosinophilic granuloma, Hand-Schuller-Christian disease and Letterer-Siwe disease.
