Re: Mucocutaneous lesions, lymphomegaly, pyrexia: differentials please :-)

Has been in Ireland for at least the last year since owners acquired as rescue dog - would seem highly improbable to have been abroad, but I have seen a confirmed case of Leishmaniasis (albeit that one went to Europe on holidays), so my mind's more open than used to be.

The periocular lesions are best described by me as mucocutaneous erythema, ulceration and crusting (there could be some hypopigmentation there also); the lip commisure and close to that have crusted/erythematous lesions, with another simliar lesion at the top of vulva. I didn't ask owner's permission to take and share a photo, but maybe should have as a picture would help more.

The enlarged left prescap turned out not to be a LN at all, but an abscess-type lesion, with a colleague aspirating red-brown purulent material from both it and the cheek lesion I mentioned in the first post.

So scrap lympadenopathy off my list of signs and I'll try again!

I haven't been around this afternoon to see the cytology from the aspirates etc.

Still think might be auto-immune disease and steroid-responsive, but suspect will hold fire until get some histopath or simliar.

Does sterile nodular panniculitis ever give you mucocutaneous ulceration-type lesions as well?

What sort of lesions?

Has it always been in the UK (or which country are you in if not UK?) - will maybe narrow down any exotic dz differentials.
