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?

  1. Looks a whole lot a Taenia! Beautiful oncospheres.

  2. Taenia eggs with radial striations on the shell

  3. 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.

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

  6. 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.
