Well, not much, except for the fact that this is pretty rare. I have
one case in the archive, so I would be interested in contacting your
vet or the pathologists to possibly get a look at this very uncommon
The source of cryptococcosis is usually not identified. Bird feces
is probably the most common source of cryptococcosis, but all of us
probably contact it every day. It is most commonly seen in humans
with immunosuppression, but the one case that I have seen did not
appear to be immunosuppressed. However, it wouldn't hurt to look

Cryptococcosis is a fungus (also known as a yeast) infection that is
most commonly seen in cats and horses. It can affect the skin only,
