I have a red spot on my left wrist, an inch up from the base of my thumb. It appeared one day a couple of years ago. Physicians get alarmed about a spot that suddenly crops up, watch it to see if it grows, scrutinize it to be certain it is not malignant, and push the dermatologist to get a biopsy if there is any question. But this spot has not gotten any bigger and in fact it is fading away. But I still pay close attention to it and look at it every day, and I hope it will not disappear.
