What on earth is this on my ankle?

[Queentwatoftwatsville]

Has anyone got any idea what this is on my ankle, it’s a raised bump of hard skin which I’ve been moisturising like crazy. I’ve had the bump for ages but the pigmentation in the middle has just appeared.

Can you remember what footwear you were wearing at the time it appeared?

My shoes come below the bump so nothing been rubbing against it recently. Thought it might have been caused by wearing boots in the winter.

It looks like rubbing from footwear, perhaps you've knocked it and broken the skin and not realised at the time

I have a couple of these. The GP said the one I showed him was a dermatofibroma. They're harmless and sometimes develop from a bite or other minor wound.
