This week's case was donated by Drs. Michael Mitchell and Theresa Smith. The following structures were seen on a Papanicolaou-stained anal Pap smear who had a history of squamous dysplasia. They measure approximately 55 micrometers long. What is your diagnosis?
Judging from the size, the location of the body, the one flat side of the egg and the presence of a folded larva inside, it is a case of Enterobius vermicularis infection.
