Hi, my boyfriend noticed about a week ago that a bubble appeared around the skin of his anus. It is dark, hard type of mass. It doesn't hurt or itch, and it's like a round smooth bubble.
Is this normal ? is it a cyst? what are the chances of being cancerous at an early age(24)? What type of treatment is normally used for this type of problem? and what type of doctor should he go to ? Dermatologist? Please help him!!
