This week's case was generously donated by Dr. Zhenwen Zhou, MD, from the Department of Laboratory Medicine at Guangzhou Women and Children's Medical Center, Guangzhou Medical College, in Guangzhou, People's Republic of China.
The patient is a middle-aged man who found the object below in his stool. He reports eating rare beef approximately 2 months earlier.
Every week I will post a new Case, along with the answer to the previous case. Please feel free to write in with your answers, comments, and questions. Also check out my image archive website at http://parasitewonders.com. Enjoy!
