I have always had an abundance of little and big moles, and lots of freckles, and now that I’m 71 I get these little round dry patches, about the size of a dime, that itch. Anyhow, since I can’t see my back, I did some contortions and saw that on my back are 3 dark moles (typical for me), one of which seems to have that dry patch on it and itches. Of course …. me, with my catastrophic thinking, is sure it’s malignant melanoma and I’m going to die within the year. I know how ridiculous that must sound, but that’s the way my mind works. I have an appt. with my Internist this week and I want her to look at all these patches and especially that on my back. I just wish I didn’t worry about things so much. What in the world are these round dry patches anyway?
