I guess it's Schistosoma mansoni egg. In pic 1 there is lateral spine, I think.

While my knowledge of clinical pathology is almost null, the structures do not seem to have the morphological details of parasites. We usually have a saying in the lab:”No head, no tail, no parasite”. We are anxiously awaiting for an educational session.

Agree that the first two photos depict eggs in the mucosa and that image 1 looks like a lateral spine, all this pointing to S. mansoni. Image 3 shows a longitudinal section of a fluke with a ventral sucker, most likely an adult S. mansoni out for a stroll.

Agree with Schistosoma mansoni eggs and adult.

Image 3, miracidium ?

Third image does not appear to be an egg as seen in the other two photos. Is it possibly a (sort of) sagittal section of an adult female?

Female is skinny.
