Growth on hind leg unknown

Hey Vets! curious on something hope you can help. a couple months back I had taken my 6-8 year old Husky to emergency vet per my vets instructions because of possible bruise on the one leg in the back. The ER vet shaved the are and discovered what they said to be skins tags. so I followed up with our main vet. Who hasn’t been able to pin point it exactly and when she tried to take a needle to get some of the cells to look under the microchip she wasn’t able to get much to provide any helpful information. She said by what she sees at that moment it wasn’t alarming but if it didn’t heal or grew we should remove it. well it’s now looking like this (I’ll attempt to attach pictures) pink on color most hair has been lost in the growth it appears to be bumpy shaped growth. im just curious is this a wart ?   thanks for you guidance on this. -Ali

Hello and I appreciate your concern about the lesion on your husky's leg.  I'm afraid that if I could look at that and say 'oh, you don't need to worry about it; it's just a wart,' with any conviction, then your vet would already have done so.  Unfortunately, two identical lumps can turn out one of them to be cancerous and the other to be inflammatory in origin; your vet simply cannot tell by looking and neither can I. If a histiocytoma seems likely (usually in dogs of up to 3 yo) then vets will sometimes delay removal until they have given it chance to vanish on its own accord.  However, a biopsy or removal is the treatment of choice for most small skin lumps.  I hope that something here helps.  There are multiple articles about this kind of issue in the blog, including one I wrote some years ago which I beleive can be searched for by virtue of having 'lump' in the title.  Wishing you both all the best from here.
