Eye Spy With My Little Eye - Negatively Staining Rods in an Ear Lesion!

It was 5 pm on Friday and I was just finishing up my Pocket Pathologist cytology cases for the week.

This one just came across my desk and is by FAR my favorite! It's not something I see every day, but it's something you in general practice should be aware of.

This is a 5yo NM hound mix. About 1 month ago had two ~1cm round firm skin masses appear on the outside of each mid pinna. Non-pruritic, not changing. All else normal.

Do you see what I see?

If you don't, fret not.

Check out this 5-minute rounds where I go over this case and reveal the answer!

Isn't that COOL?! Have you seen this in practice before?
