Mole With White Ring Around It

I have a mole that looks normal, raised, brown, the size of a pencil eraser but this summer it developed a white ring around it. Is this something to worry about?

Answer

Hi Kris

I think I know what you are talking about as I have a couple of these myself. I pointed them out to my dermatologist who told me that these are called halo moles.

Basically the body has decided to attack the pigment and eventually the mole will disappear completely.

The American Osteopathic College of Dermatology explains:

"Sometimes halo moles are triggered by sunburn that damages the mole and causes it to be recognized by the body as foreign. A circulating antibody and special white cells (T cells) attack the pigment cells in the mole. This causes the central mole to fade from dark brown to light brown to pink, eventually disappearing completely."

You do want to get your halo mole checked by a dermatologist as it can be part of "...a more generalized pigment loss, vitiligo, or in melanoma."

My halo moles were no problem and simply vanished over time but you do want to get yours checked out just to be sure.

Hope this helps some. Thank you for your question.
