Thanks for the medical terms as they were actually a lot of help as they lead me to the "SkinSight" website with tons of pictures and details.
I decided to go to the State University Dermatology Center as I assume they are much more interested and thorough than the hurried & careless dermatologist down the street.
Trust them to do a good check. just don't leave their office until you are happy.
There are lots of odd moles that can turn up in older age. Look up senile warts, solar lentigos, neurofibromas, and angiomas. Good to get new ones checked over once though.
Take care. The fluid filled one sounds odd so make sure they look at that one.
