Case of the Week 131

Here's a more straight-forward case than our recent ones:

The following object was seen on stool ova and parasite examination and measures approximately 15 micrometers (Modified Trichrome stain, 1000x). (CLICK ON IMAGES TO ENLARGE)



The following was also seen, measuring approximately 20 micrometers in greatest dimension.


Identification?
Would the fact that the patient is asymptomatic make a difference in your diagnosis?

    E. histolytica, I would say also.

    E.hystolytica/dispar. The patient is asymptomatic and I don't see ingested RBCs so it would be hard on morphology to be 100% sure this is E.hystolytica. JH, VT.

    I agree with E. histolytica/dispar.

    The absence of digested RBCs and the fact that the patient is asymptomatic suggests E. dispar rather than E. histolytica.

    E. histolytica/E. dispar. The fact that the pt is asymptomatic makes me favor E. dispar.
