My Mole Has a Dark Red Ring Around It, is It Dangerous? (photo)

I would highly recommend that you see a board certified plastic surgeon or dermatologist for a proper evaluation and possible biopsy.

In my opinion I would see a board-certified dermatologist to evaluate the lesion. We frequently talk about the ABCDs of melanoma, which stands for Asymmetry, irregular Border, varied Color, and large Diameter. But there is also an "E" (i.e. ABCDE) that stands for Evolving or changing. Have a dermatologist check out the pigmented lesion and see if it should be biopsied or removed. Good luck.
