Shown here is the blood smear from a patient with carcinoma. If many NRBCs are present in the blood smear accompanied by younger forms of the granulocytic series, the leukemoid reaction is a special kind called a leukoerythroblastic blood picture. Anemia is usually present with or without hemolysis. If many NRBCs are seen in a blood smear (over 10/100 WBC), a leukemoid reaction rather than leukemia should be suspected. A leukoerythroblastic reaction is seen more commonly in metastatic tumor than in infection.
