Case #368 - March 2014

An eight-year-old child presented to a hospital with intermittent fevers. He had recently returned from a trip to Kenya and had not taken anti-malarial prophylaxis while traveling. Blood was collected in EDTA and sent for hematologic work-up. A BinaxNOW malarial antigen test was performed and the result was negative. Thin smears were also made and stained with Wright-Giemsa. The attending technologist who read the smears took digital images of her findings and sent them to the DPDx Team for a telediagnosis consult. Figures AD show four of the images received for analysis. What is your diagnosis? Based on what criteria?
