Case of the Week 235

This week's case is a bit challenging.

The following objects were seen in a Papanicolaou-stained endocervical preparation by the screening cytologist and brought to the microbiology lab for identification.  They measure approximately 8-10 micrometers in diameter.  The woman is asymptomatic.  (shown at 1000 times original magnification)

 



Identification?

Possibly a free living water organism?

The morphology did not demonstrate the elements pertaining to T. vaginalis such as: flagella, blepharoplast, undulating membrane, axostyle and elongated nucleus. The nucleus is rather round and seems to have a peripheral ring and a central karyosome like those of amoebas. Based on this I tend to agree with Lee that the organism could be an amoeba.
