The DPDx Team received stained stool smears from the Vermont Department of Health Laboratory for Entamoeba identification. The patient was a 12-year-old refugee from Myanmar who had also traveled to Malaysia. The patient's stool had been collected in sodium acetate-acetic acid-formalin (SAF) and sent to the state laboratory for processing. Figures A-F show what was observed at 1000x magnification on a smear stained with iron hematoxylin. What is your diagnosis? Based on what criteria?
