Pulmonary sarcoidosis masquerading as tuberculosis.

Pulmonary manifestations of sarcoidosis are common and may be initially confused with other common diseases like tuberculosis. We report an 11 yr old girl who presented with chronic cough, low grade fever, recent exposure to tuberculosis and hilar lymphadenopathy. She was provisionally diagnosed as pulmonary tuberculosis and treated accordingly. As she had poor response to anti tubercular therapy, diagnosis was subsequently revised to sarcoidosis by lung biopsy. Treatment with steroids resulted in significant clinical improvement.
