I too have never heard of this and am having my own concerns about a rash I developed on my radiated breast which has come up in the last 5 weeks (as I discuss in my post titled "rash"). My radiation oncologist told me last Friday that she thinks I have erythrasma which is a staph infection of the skin. She gave me new ointment but after treatment for 4 days still no change. Your post just goes to show that we need to be on the ball with these things. I am sure mine is fine, but if it doesn't go away in another month I will be pushing for a punch biopsy just so I can ease my mind.
Thanks for sharing
