Good golly - Lisa, no I've never heard of it before and I'm sure my vet hasn't either....but I don't think that's what hers is. When I looked at the link that Scoobs posted above, my jaw dropped. I have a dog with those same 'lesions' - the vet hasn't been able to identify them. They're definitely not 'small crusty nodules' at any time in their life cycle. That said, Doc's always had what I would describe the same way that you did - small crusty nodules. They couldn't get anything out of them to see what they were when they tried to biopsy, just skin layers. He's got lots of them but they don't seem to itch, some disappear, others reappear. I think they're an allergy, possibly food allergy but I've never been able to change his diet long enough to tell. Since they don't bother him, we just live with it.
Her immune system is shot so she's prone to anything happening. She's always had these lesions - note the black spot at the end of the swelled areas in the link. I thought they were from the burrs still left which some were but these others aren't. I treat them when they appear but vet had NO idea past 'some kind of cyst'. Bathing often seems to help...
