I have uploaded a picture which you can fine on my profile. It is the latest pic.
I'm not a doctor, certainly not a derm expert, but it seems that this condition is "many, tiny, ridgelike bumps on the palms of the hands and soles of the feet". (https://rarediseases.info.nih.gov/diseases/8180/punctate-porokeratosis)
It looks like you only have one, but again, I don't know if it can start as one, and then get worse later, or if it starts with many.
Have you seen a dermatologist? That would be the only way to get a diagnosis and proper treatment.
Let us know what happens.
