Search for: [Abstract = "Sarcoidosis, known as Besnier, Boeck and Schaumann disease \(BSS\) is a disorder of unknown etiology, in which non\-caseating granulomas develop in many organs. The lungs and lymph nodes are affected in 90% of patients. Diagnosis is based on the clinical symptoms, chest x\-ray and computerized tomography. It is necessary to find non\-caseating epithelioid cell granulomas by biopsy of an involved organ. The diagnosis of sarcoidosis needs differentiation with diseases presenting with similar clinical signs, radiological characteristics and cyto\-histopathological evidence, including tuberculosis. The course of the diseaseis usually benign, most often there are spontaneous remissions, however a chronic course as well as recurrence may occur. In extreme cases sarcoidosis may lead to lung fibrosis, which may require lung transplantation. Treatment is indicated in approximately 30% of patients, and corticosteroid therapy is most often used.Until now there are no widely accepted standards of diagnosis of sarcoidosis. Commonly used techniques include\: EBB, TBLB, TBNA, and mediastinoscopy. The novel diagnostic modality – endosonography \(EBUS\-NA and EUS\-NA\), introduced recently into clinical practice, is a promising alternative for mediastinoscopy, which until recently was the standard method of obtaining tissue samples from mediastinal lymph nodes. These methods were not verified in randomize"]
