Langerhans cell histiocytosis. From theory to clinical practice.

Abstract

Langerhans cell histiocytosis is a disease characterized by the clonal expansion of myeloid precursors that differentiate into CD1a + / CD207 + in lesions. It occurs in all ages with varying degrees of systemic involvement and, although cure rates are high, serious long-term neurological or endocrine complications can affect quality of life. The evolution of 2 patients is presented in a table, in which it is observed that it is not always so easy to put medical knowledge into clinical practice to reach the diagnosis of diseases and even more so if these are infrequent in our environment.
