Thanks for posting your query on DoctorSpring.com.
I can understand your concern.
This seems to be a seborrheic keratosis. It's like dead skin. It requires to be burnt off (cauterized). It wouldn't be advisable to pull it out as it would cause a lot of bleeding.
I would recommend you visit a dermatologist who can burn off the lesion for you. However, this is not an emergency and you can get it done at your convenience.
Please let me know if you have any queries.
