Circular skin discoloration

I have two dime size symmetrical circles on my chest between my breasts. They are a few shades darker than my skin tone. Have been there for two+ months. They don't itch, aren't red or irritated in any way. They aren't raised off the skin. They just appeared one day. Wondering what these might be and if it is worth going to the Dr. for. Thanks

Hello,
These can be due to pityriasis versicolor or pityriasis rosea. If they are itchy then nummular dermatitis and ringworm need to be ruled out. Nummular dermatitis is a form of eczema which presents as circular dime like spots on different parts of body.

I sincerely hope that helps. Take care and regards.
