Case #449 – August, 2017

A seven-year-old female from Sudan had a stool examination as part of a refugee screening.  Her blood workup also revealed elevated eosinophils. A formalin-ethyl acetate (FEA) concentration was performed on the stool specimen and Figures AD show what was found on a wet mount preparation.  What is your diagnosis? Based on what morphologic features?

This case was kindly contributed by the State Hygienic Laboratory, University of Iowa.
