I have a challenging case for you this week!
During routine colonoscopy for colon cancer screening, endoscopists noted the following worm-like objects in the cecum:
One of these objects was removed and sent to surgical pathology where it was fixed in formalin, paraffin embedded, and sectioned for staining with hematoxylin and eosin. Unfortunately, no intact objects were sent to microbiology for identification. The portion of the object shown measures 2.5 mm.
