This week's case was generously donated by Drs. Taylor Williams and Karl Kirby. The following object was passed per rectum by a child living in the Western US without travel outside of the country. The family also does not report any international travel. What is your differential diagnosis?

Diphyllobothrium sp proglottids
From what I have seen so far, the objects may suggest a Diphyllobothrid tape worm. Yet in the second picture, the object on the right hand side has the sections longer than wide, not typical of craspedote proglotids. The pictures didn’t show a clear line of central reproductive organs. I would press the sections to see if it produces the ovoid operculated ova and Carmine stain before coming to an identification.
It is not parasite, because there is no obvious internal organ. This could be some undigested food wrapped with mucous
Interesting….looks “weird”; NOT a parasite??
Not a parasite I think. Would look under a microscope though./Patrik
