title: Acute myelogenous leukemia mimicking fulminant periorbital cellulitis.
abstract: OBJECTIVE
  To report a patient who was referred for orbital cellulitis but was finally diagnosed with acute leukemia.
  
  
  METHODS
  A 17-year-old boy presented with fever, periorbital erythema and swelling mimicking periorbital cellulitis. He underwent empiric antibiotic therapy. Complete blood counts revealed leukocytosis with a predominance of immature blast cells. Bone marrow aspiration confirmed the diagnosis of acute myelogenous leukemia. Chemotherapy was initiated resulting in resolution of signs and symptoms.
  
  
  CONCLUSIONS
  Acute leukemia may mimic periorbital cellulitis and must be considered in the differential diagnosis.
