Of the difficulties of differential diagnosis of tuberculosis and sarcoidosis: clinical case

The article presents the results of 2-year follow-up of a clinical case that confirmed the nosology of the identified case not only with immediate, but also with long-term results. This case allowed to verify the diagnosis of pulmonary sarcoidosis and effectively help the patient despite the presence of very convincing radiographic findings of tuberculosis and complex time-consuming diagnostic search. The most significant contribution to the establishment of the etiology of the disease was made by such a modern highly informative research as immunohistochemistry.
