This week's case was kindly donated by Monica Jarvis and Liliana Arias. The patient is a young child who lives on a family farm. The mother noticed "worms" in the child's stool and submitted them to the laboratory for identification.

What is this?
Hymenolepis nana
ReplyDeleteDipylidium caninum: proglottid (macro) and 6-hooked embryos in eggs (packets or single eggs)
ReplyDeleteDipylidiun caninum
ReplyDeleteOnce again, the dog or cat relieves it's anal itch and passes its double pores proglottids into its human dwellings. The proglottids disintegrate and release the brood of packets of eggs. Dipilidium caninum has been found not only in dog but also on cats.
ReplyDeleteThe freshly passed proglottids are motile but soon shrink in size to that of a small rice grain and become motionless.

Adorable little proglottids!

ReplyDeleteAs there are no measurements available for the ova and no great detail on the proglotidd, my diagnosis would be solely based on the appearance of the ova and the patient being a child. My diagnosis would be Hymenolepis nana. 6 hooklets can be seen in the oncosphere, and polar filaments can just about be seen.
