Case #229 – June, 2008

Wright-Giemsa stained blood smears and EDTA blood were sent for confirmatory diagnosis to the CDC from a Public Health Laboratory. The specimens were from a 46-year-old woman, but no travel history was available. Image A was captured from a stained thick smear; images B, C, and D were captured from a stained thin smear. All images were taken at 1000x magnification. What is your diagnosis? Based on what criteria? What other testing, if any, would you recommend?
