This patient presented with a normal white blood cell (WBC) count and slightly decreased hemoglobin and platelet count. The most notable finding was marked eosinophilia.
A manual differential was performed, which revealed 48% neutrophils, 13% lymphocytes, 9% monocytes and 30% eosinophils. Red blood cell (RBC) and platelet (PLT) morphology appeared normal.
An increased eosinophil count is usually associated with allergy, parasitic infection, and certain autoimmune and myeloproliferative diseases, where sustained eosinophilia may result in organ damage (Gotlib).
