Histiocitosis de células de Langerhans cutánea autolimitada en adulto. Caso clínico y revisión de la literatura

Langerhans' cell histiocytosis is rare; its prevalence is only 0,5/100,000 cases per year and these are predominatly children. As opposed to congenital self-healing histiocytosis (reticulohistiocytosis) which has affects the skin, Langerhans cell histiocytosis can present systemic manifestations (bone, liver, spleen, etc.). The prognosis and the treatment depend especially on the age of the patient, extent of the lesion and the number and dysfunction of the organs involved. We report an unusual case of LCH in an adult male with only cutaneous pathology and a self-limiting evolution.
