Porokeratosis - single spot

[Anonymous]

I have an issue that is dermatologic/podiatric but the internet has practically no useful resources that I could find.

I have a painful callus with a a deep center on my foot, have had it for years. I've been doing the peel-treat type of treatment for we a while and it is very stubborn.

Podiatrists have called it a "porokeratosis"/"porokeratoma", which it may be but it is the one spot and doesn't really match the descriptions of this disease on dermatology websites at all. In fact I can't even figure out if the dermatologists and podiatrists are talking about the same thing.

Nothing on Reddit.

Anyone have experience with this?

It’s not a planters wart?

Agree with previous poster, sounds very much like a plantars wart. They can be stubborn.

OP here. Could be. It's under so much callus it's hard to tell. It's on the big toe and it's very much a big dot, but with with a deep "core". I get that the treatment is similar, but reading about porokeratosis it's all scary, could be precacerous, etc.

OP many years later. It doesn't appear to be a wart. I've been able to work it down almost all the way with cantharone treatments but it comes back in due course. Still no clue what to do about it.
