WTF is this- nipple on my arm

[Gawdimold]

Wtf is this on my inner arm. I thought it was a freckle but not it’s sore and itchy. Will dr send me away laughing. Looks like a nipple!’

Is it new?

https://www.bad.org.uk/pils/seborrhoeic-keratosis ? I am starting to get these in my 50s.

No harm in getting it checked.

Definitely looks like a seborrheic keratosis.

I had one that looked exactly like this, I went to the GP and was referred to a specialist and they confirmed it as a seborrhoeic keratosis.

They confirmed it was a harmful lesion. Always best getting checked out though.
