Leucocytosis in a case of sarcoidosis with pleural involvement--an unknown association.

The resolution of neutrophilia and other disease manifestations with azathioprine points towards sarcoidosis being the probable cause. GG, 45 years old male, presented with fever and right-sided chest pain with biochemical features of granulomatous hepatitis and apparently unexplained leucocytosis.
