[Sarcoidosis--clinical features, diagnosis and treatment].

Sarcoidosis is a multisystem disorder of unknown aetiology. Pathologically it is characterized by the presence of non-caseating epithelioid-cell granulomas in the lungs, intrathoracic lymph nodes and other affected organs. The clinical course of sarcoidosis is widely variable, ranging from asymptomatic but abnormal findings in chest radiography to progressive multiorgan disease, which leads to fibrosis with organ failure and functional impairment. The aim of this article is to familiarize physicians with clinical features and treatment of this disease.
