SARCOIDOSIS UNDER THE GUISE OF DRUG-RESISTANT TUBERCULOSIS
Sarcoidosis is a systemic inflammatory disease of unknown nature, which is characterized by formation of epithelioid cell granulomas in different organs and tissues without caseous necrosis. Historically, the correlation between the two nosologies, sarcoidosis and tuberculosis, was based on the early assumption about etiological similarity of the diseases and numerous clinical, immunological, and radiological common features. Despite significant advances in medical science, differential diagnosis of these systemic granulomatous diseases remains challenging for modern pulmonology and phthisiology. The article describes a clinical case of a 20-year-old patient, who had received TB treatment before the diagnosis of sarcoidosis was verified.
