Case of the Week 608

 This week's case is from Dr. Peter Gilligan. It's a histopathology image - which I know isn't always popular with the classical parasitologists! But I think you might be able to take a stab at the diagnosis regardless. The following eggs were seen in an ulcerated area of an intestinal biopsy. They measure approximately 30 micrometers in diameter. Identification?

Taenia eggs with radial striations on the shell

Taenia species eggs.

The smaller size of thirty microns in diameter and the striated thick shell is consistent with a Toenia species ova identification. The identification to the individual species level is not achievable. The hooklets are not discernible in this case.

Are we assuming this is a human biopsy? If not, Taenia eggs can’t be differentiated from Echinococcus eggs. Just a thought. Nice images!

AZ Parasite brought up a very valid opinion. How can we make a differential diagnosis between Toenia and Echinococcus app. ? These eggs are so similar in morphology and size.
