[Sarcoidosis--rare clinical form]

The paper presents a case of a 46-year old male patient in whom numerous asymptomatic round shadows in both lungs were diagnosed. The pulmonary diagnostic tests confirmed the diagnosis of neoplastic dissemination of unknown origin. The broader internal diagnostics did not confirm a neoplastic cause of the changes. The histopathological examination of the supraclavicular lymphonodus lead to the diagnosis of chronic, III degree sarcoidosis including the involvement of the lung parenchyma and peripheric lymph nodes. The lung radiography - atypical for sarcoidosis (owing to the lack of hilus lymphadenopathy) - was the cause of the false primary diagnosis.
