A case of histiocytosis combined with pulmonary tuberculosis in a young woman (clinical observation)

Pulmonary histiocytosis is a rare disease of the group of interstitial lung lesions of unknown etiology, associated with difficulties in diagnosis and treatment and an uncertain prognosis. We present a clinical case of a combination of tuberculosis and histiocytosis in a young woman. This clinical case demonstrates the difficulties in establishing a correct diagnosis due to the lack of pathognomonic clinical signs, the need for pathomorphological verification of the diagnosis, an unfavorable course of the disease, which, despite the abatement of the tuberculosis process, led to a steady progression of pulmonary histiocytosis with the development of severe respiratory failure, which led to a fatal outcome.
