Eosinophilic granuloma Complex?

Hello Vets..My 15 year old male has eosinophilic granuloma complex..he has missing fur on his belly, ears, the two dots on the side of the planum part of his nose and now has this on the bridge of his nose..The bridge of the nose is the thing that concerns me..Is this part of having EGC too? He eats, plays, goes to the litterbox and acts perfectly fine otherwise..Thank you..Pictures attached

Hello!   I'm afraid that I can't see any pictures, but I'll try to answer your question.  My understanding is that cats can get eosinophilic granuloma complex presenting anywhere on the body - it is a disease of the skin, and skin is rather widespread, including the bridge of the nose.  Obviously there are common sites for it to occur - in this case, I would say on the lips, below the nose and in the mouth.  But - as a mentor of mine used to say - not all cats read the text-book before getting ill and without testing, I would rarely rule something out, unless I had managed to rule something else in that completely explained what I was seeing (and even then sometimes, there can be two things going on at once).   A strong differential for a lesion on the nose might be ringworm, which occurs on the bridge of the nose very commonly.

Usually, if presented with something red and splodgy on the nose, I would try to rule ringworm out before EGC because it is such a common presentation and treatment can be fairly reliable.  However, this is something to talk over with your vet, who has hopefully seen the patient and therefore has evidence to base their comments on.  Vets usually enjoy explaining their thinking on clinical matters when asked.

Have you had a straight conversation with your vet? Since ringworm is such a common presentation and has a somewhat dependable treatment I would try to rule it out before EGC if the patient arrived with anything red and splodgy on the nose.
