I've had this for years, but do not remember it ever appearing. I was not born with it though.

Is it a birth mark? Is it removable by a dermatologist?

Any idea what this could be? One picture is a close up while the other is of the area. It is on the right side of my torso.

  • Hi AlexanderP,You probably don't need to worry too much about this. You're going through adolescence right? If so, that's very likely something called a 'Becker's nevus' (pronounced beaker's neevus) ... it's basically a birthmark that doesn't appear until adolescence. I have one too. I posted about it recently but nobody could help me so I went to the dermatologist and he took a biopsy of my arm. According to the doc it's a condition that's _completely benign_ where there's too much muscle tissue in the hair follicle, or it's overactive, so it forms little bumps sometimes and the skin is colored a little darker too as a result of the muscle. From what I found so far, best thing you can do for it is keep an eye on it, don't scratch (rub, if anything), and don't stress out too much about it. When I worried and stressed about it, i just got more bumps and i would scratch the bumps and then they would scar and stay there forever... so don't fuss it too much. Also one thing I forgot to mention is that sometimes more hair grows there than other places. I heard that some people got a tattoo over theirs but I haven't tried it yet or verified how safe that is. If you get worried about it getting bigger (which it probably will do, and then stop at some point), then I'd say go to a dermatologist, or your regular doc and he can refer you to someone, and let them know about it. As for removing it, some laser companies report that it can be removed by a certain type of ruby laser (similar to tattoo removal), but people who say they actually tried it report scarring, and I also doubt it would remove the bumps. But treatment/removal of it seems to be a relatively new thing so don't give up just yet. Maybe something will be developed, or it already has been and we just dont know about it.Best,Paul

  • Hi again,I was just looking online today and I found this case study of a 19-year-old man who was diagnosed with a becker's nevus, but it turned out to be something apparently different called a smooth muscle hamartoma. The symptoms described in the case study match mine more closely (for example, the speckled coloring and few vellus hairs, etc.). I thought you might find it informative and helpful if you decide to try to go to the doctor for a biopsy or anything.Here's the link: Acquired smooth muscle hamartomaHope it helps.BestPaul
