Case #450 – August, 2017

A 26-yo man, who recently emigrated from Northern Africa, presented to his primary care provider with complaints of abdominal pain, diarrhea, and weight loss for the preceding 6-8 months. He was later found to be leukopenic, neutropenic, with elevated eosinophils in the peripheral blood. Stool preserved in SAF was sent to the laboratory for ova and parasite examination (O&P) and the objects shown in Figures AC were observed in a formalin-ethyl acetate (FEA) concentrate/iodine prep. What is your diagnosis? Based on what morphologic features?
