title: Granulocytic sarcoma of the lung in acute myeloid leukemia.
abstract: BACKGROUND
  Granulocytic sarcoma, an uncommon solid, extra-medullary tumor is a rare presentation of acute myeloid leukemia.
  
  
  METHODS
  A seven-year old boy admitted to the hospital for treatment of leukemia having radiological findings of consolidation in one lung.
  A bronchoalveolar lavage was done which was negative for tubercular, bacterial, and fungal infection but showed blast cells.
  
  
  RESULTS
  On day seven of chemotherapy, a repeat chest x-ray showed resolution of the lesion. A high-resolution Computerized tomography of chest repeated after one month of induction showed resolution.
  
  
  CONCLUSIONS
  A consolidation on chest radiograph in acute myeloid leukemia can be a granulocytic sarcoma of the lung; a bronchoalveolar lavage may be offered to confirm or refute this diagnosis.
