Case of the Week 762

 This week's case comes from my own lab - an unexpected finding on routine colonoscopy. These beautiful photos are courtesy of Felicity Norrie. Identification?

Good to be back after a hectic period! It’s been too long since my last post… :-)
About the case:
The ribbed cephalic alae are typical for an Enterobius vermicularis adult. The curved tail and spicula (although retracted) point towards an adult male.

Idzi’s beat me to it. For sure I agree totally with his clues and identification. Since the worm is a male one, the patient wouldn’t have nocturnal perianal pruritus.

Enterobius vermicularis. We saw one here this year under the same circumstances.
