Case #377 – August 2014
A 22-year-old man had a post-travel medical evaluation that included hematologic work-up after returning from an 11-day missionary trip to Honduras. Blood was collected in EDTA at a medical center and thin smears were prepared and stained for examination. The stained smears were forwarded on to the State Public Health Laboratory for confirmation for diagnostic assistance. Digital images were captured at 1000x magnification with oil by the attending microbiologist at the PHL and submitted to the DPDx Team for a telediagnosis consult. Figures A–H show eight of images that were sent for analysis. What is your diagnosis? Based on what criteria?
