welcome to healthcare magic forum .
thank you for your query .
it do not look like as mole .
also i said that it is not normal
it may be due to some infection
heredity may be the reason for that ,but do not develop so speedy
it is always better to consult dermatologist
as fast as you can
wear him cotton cloths
never pick or pull the mole like lesion .
i hope i answered your query .
