Case #477 - October, 2018
A 58-year-old male, with recent travel to Asia, was seen at an out-patient clinic for abdominal discomfort that lasted for two days. A stool sample was collected in 10% formalin and zinc PVA (Zn-PVA) and processed for ova and parasites (O&P) examination. A presumptive worm egg was recovered from the stool and was processed in the pathology laboratory for identification. An image of the hematoxylin and eosin (H&E) stained slide is shown in Figure A. What is your diagnosis? Based on what morphologic features?
