Case of the Week 369

This week's case was generously donated by Dr. Jane Hata. Several motile structures were seen in a bronchoalveolar lavage from an elderly woman with rapidly progressing shortness of breath and edema. She had a history of chronic heart failure and was receiving immunosuppressive medications for a renal transplant some years prior.

Identification?

Dear Bobbi,
Round shaped flagellated protozoon.

Protozoan. Trichomonas hominis?

Not parasite

epethelial cells

Despite the immunosuppression, I cannot think of any flagellated protozoan respiratory pathogens, so I would say ciliated respiratory epithelial cells.

Ciliocytophthoria (detached ciliated epithelial cells). No parasite identified.

Ciliocytophthoria, these detached ciliated epithelial cells may at times mimic ciliated protozoans.

I do not believe this is a parasite. More likely Ciliocytophthoria. The differential would be any ciliated protozoan that can infect humans, Balantidium coli would have been a possibility due to the site of infection and the fact that the patient was immunosuppressed. However the morphology is distinctly different from that of B.coli, which is very (very!) large in its ciliated trophozoite form and is covered in short cilia rather than a localised patch of long cilia. It also has a distinct peristome and kidney shaped macronucleus which is not present here.

Lophomonas blattarum, possibly
