This week's case was donated by an internal medicine resident, who passed the object shown below in his stool. He reported intermittent post-prandial abdominal pain and loose stools for several years, and a complete blood count 2 years ago showed peripheral eosinophilia. He has an extensive travel history, including trips to regions of Asia and Africa, where he ate the local food.
He unfortunately didn't save the specimen to submit to the laboratory since his wife was too grossed out and flushed it!
This resident now wants to know what to do next.
1. What is your presumptive identification from these photographs?
2. What is your advice for further identifying the nature of this object?
