[Necrotizing systemic sarcoidosis with pulmonary and central nervous system involvement].

Sarcoidosis is a multisystemic disease which diagnosis depends on the presence of nonnecrotizing granulomas in the biopsy. However there are variants such as necrotizing sarcoidal granulomas or nodular sarcoidosis which have atypical findings and make difficult the differential diagnosis with other infectious processes. We describe a case of a man who develops granulomas with extensive necrosis in a systemic sarcoidosis that affected the lung and the central nervous system. This finding made us to make the diagnosis of tuberculosis and delay the specific treatment.
