Welcome to our 800th case! Given the occasion, I thought we deserved something spectacular, and these images from Heather Morris definitely fit the bill. These worms measure ~1 cm long. What is your diagnosis?

There are only a few scenarios like this. Fortunately the cephalic alae and the magnitude of eggs in the pictures tells me of a nightmare of a nocturnal pruritus. I may need to observe closely for the lobsided aspect of the eggs. One side flat, the other side curved upward.

Enterobius vermicularis (pin worm)
The majority of patients with the worm are children, they’re altruists and love to share. Formerly there was a practice of “deworming” the dwellers of nursing homes. The good thing is that it stops the spread of infection. The practice has been stopped, and these days the laboratories may be busy with a bunch of patients from a nursing home. Some of them may have the wiggling worm. I have seen this situation a few times, but I would refer the policy to epidemiologists and infectious disease specialists or the CDC ?

The second picture is impressive, I wonder if pin worms adults autofluoresce under UV excitation.

Enterobius vermicularis.
I want to know how the specimen was taken, I always see the females full with eggs, but in the images you can see through.
And how to make that beautiful blue hue in the second one.
Absolutely stunning photos for this case, congratulations on the 800th!

Was the first picture taken with dark field microscopy or some other illumination?
