Campbell De Morgan spots are harmless red spots that can appear as we age. They develop from an abnormal proliferation of blood vessels. They can get larger as time goes on and are often noticeable over the chest and abdomen (although they can appear anywhere). Luckily they are easily treated with a little bit of (almost) painless diathermy. Here are the results of a noticeable chest lesion after one treatment. With some protection from the sun in the long term there should be no noticeable mark left behind. Prices start from $5 a spot and take only minutes!
