Case of the Week 718

Welcome back to our first case of the month, with a special case from Idzi Potters and the Institute of Tropical Medicine, Antwerp.  The following structures were found in a bronchoalveolar lavage from a middle-aged Belgian patient with asthma who presented with increased shortness of breath. He reports no travel out-of-country and works as an administrator at an insurance company. He recently reported an insect infestation in his home.Video credits are for Monique Vatlet (CHU Ambroise Paré, Mons, Belgium).


Identification?

I believe seeing this before. My guess is ciliocythopthoria.

Not a parasite. Respiratory ciliated epithelial cells.

I have never heard of it. Internet Research shows:

so the diagnosis epithelial cells mayx not be wrong?

This wonderful parasite is ciliated protozoan called as Lophomonas blattarum

This is some thing i never seen before.

I agree that this is Lophomonas blattarum most likely from the insect infestation if it is cockroaches and since it is missing the characteristic columnar shape, and terminal bar and inserted cilia at the apical end you would expect from a ciliated bronchial cell.

very interesting case and never seen before to me as far as i am concerned..still identify cilia at one end ..which is not matching with any human ciliate ...thus bring us to consider to be a zoonotic parasite related to her recent inscet infestation

Si, è una Lophomonas spp, forse L. blattarum ( Sir Galahad )
