I have a small blood red circle on my scalp. maybe the width of a straw tip. the center is flesh colored. no hair loss. no irritation. ?

CutaneousCropCircle?: There are a number of potential causes, all of which are benign- like a small capillary hemangioma, a small fibroepithelioma (pyogenic granuloma), a fibrous pilloma or maybe an uncommon form of a common wart. If you are worried about the cosmetic effect, or if it bleeds or grows or causes irritation, or if it spontaneously bursts into flames, see a dermatologist.
