Resolución de múltiples nódulos pulmonares cavitados con el abandono del hábito tabáquico como único tratamiento

The term histiocytosis refers to a heterogeneous group of diseases characterized by the infiltration of Langerhans cells (LC) in different organs. Pulmonary Histiocytosis (PH) is an uncommon disease that typically affects young adults. Its pathogeny is not well known, although a relationship with smoking has been observed. Thus, the first treatment measure should be smoking cessation. We present a case of pulmonary histiocytosis that showed a favorable clinical, functional and radiological course in six months as a consequence of using smoking cessation as the only treatment.
