Trophozoite of Giardia duodenalis due to the presence of 8 flagella and two nuclei. Giardia typically remains contained to the GI tract, so perhaps the lymph node was being sampled through the small intestine. The presence of intestinal epithelium in the cytology sample would be helpful in confirming the specimen was obtained in such a manner if the approach of the procedure or location of the lymph node was not known.
These trophozoites of Giardia lamblia cannot be stained any better. It's not always easy to stain all the flagella, parabasal body and axiostyle all at the same time. I suspect there was a incidental aspiration of the intestinal contents while performing the lymph mode aspiration.
Giardia; perhaps there was contamination during procedure if the sample was from an abdominal lymph node and bowel was punctured during the attempt. Or maybe there was a bowel resection performed during a oncologic procedure requiring regional lymphnode sampling as well.
Looks like Giardia to me, you can see both nuclei if you look closely. How did it get in there? Maybe contamination during sampling? I know that some parasites will disseminate in immunocompromised patients, but I had not heard of that happening in Giardia.
Trichomonas!
ReplyDeleteGiardia duodenalis. Binucleated, 4 pairs of flagella.

Giardia. But how did it get into the lymph node?
ReplyDeleteGiardia...where was the lymph node (anatomically?)

ReplyDeleteGiardia. Was this a trans-duodenal aspirate?

ReplyDeleteStrange for that type of aspirate but looks like Giardia!

ReplyDeleteGiardia lamblia Being a luminal intestinal parasite How did it get into the lymph node?
