title: Concurrent chronic myelogenous leukemia and tuberculous lymphadenitis: a case report.
abstract: BACKGROUND
  Double pathology is uncommon. The diagnostic effort must be directed toward uncovering a disorder that can explain all the findings in a given patient. However, exceptions occur, notably in the sphere of infectious disorders. This is particularly true in the context of multiple infections in immunocompromised patients.
  
  
  METHODS
  Fine needle aspiration was performed on 2 lymph nodes in a 22-year-old male. Extramedullary hematopoiesis was seen in 1, while the other showed acellular necrosis with acid-fast bacilli. The hematologic workup revealed chronic myelogenous leukemia.
  
  
  CONCLUSIONS
  Extramedullary hematopoiesis can be a cytologic clue to hematologic disorders. A search for an additional infectious disease may be in order.
