@4drmoz: How worried should you be if you have a similar spot? Thankfully not that worried. This is simply a collection of blood vessels really close to the surface of the skin. Sometimes it gets called Angioma Serpiginosa as the pattern when these things look bigger can appear to mimic a snake - though I have to be honest I never see a snake. They typically grow in young adults, women more often than men (just like this case) and are basically a cosmetic problem. Thankfully not a cancer but fascinating to look at nonetheless! #skindoctor #angioma #skin
