Hi Hip....I don't know how old you are, but I'll say that with old (older?) age comes many skin changes. I think the more sun exposure and the fairer we are the more inclined we are to have them. I'm very, very fair and have everything from cherry angiomas (along my stomach) to a recent recovery from particularly a nasty rash due to an unknown med (or vitamin, etc.) that has taken 3 mos. to heal.
Some of them look like angiomas while others look fungal in nature. There are prescription creams that will take care of them without treatments that are too long. I do think you should see a dermatologist, as has my dark skinned husband who also had fungal infections has done. We've been with the same determatologist for about 42 years. He could never tell us anything, but always had a prescription which never took it away.
Fast forward to about 2 mos. ago when I suggested (once again) that he'd had enough opportunities, perhaps Rod should see a new dermatologist. She was a recent grad, but immediately knew what the problem was, said it was common and should go away within a mo. or 6 wks. Gave him a prescription cream and it worked!! So that's who we're with now...someone who knows what she's doing. I've also checked out things with my internist before today, and she has readily identified the problem and tells me what to do. (I tend to get skin cancers across my nose.)
I've used a quality sunblock (Elta) for years, but would like to warn people about buying things like that on Amazon. The bottle's are slightly different, the price lower and you think you're getting the same product. Wrong, there are a lot of made-up products on Amazon, especially among those for women. Don't think you're getting the real deal when in many cases it's fraudulent. I guess we should all be aware of that advice.
If you're seeing your internist soon, check with him/her. If not, I would go directly to a dermatologist...it doesn't seem serious, isn't spreading, but then my problem was only a flake of dried skin and turned out to need major surgery. (I had to see a plastic surgeon and it took way over a year to heal.) I honestly don't think you have to worry about cancer, but fungal....perhaps. I'm glad it's not driving you crazy with itching.
You've been a wonderful help to so many on here, so perhaps it's our turn now. Yours, Lenora.
