Most dark nail streaks are totally benign…but not all of them! If you are concerned at all about any nail streak, I would highly recommend you get it evaluated by a dermatologist. 👉 A dark brown streak in the nail, which is known as longitudinal melanonychia, is most commonly benign and the result of blood, a mole, genetics, pregnancy, or even a foreign body underneath the nail. However, in some cases it can turn out to be melanoma, which is a cancer that can spread throughout the body if not removed. 😷 If you have had a dark streak for many years or have it in multiple fingers, it may simply be related to the pigment in your skin. In that case, it is less worrisome. 🚨 If you have a new dark streak that has been present for more than a few months, I would have it checked out by a dermatologist. If it needs to be excised, feel free to come see a hand surgeon like myself. #nails #melanoma #cancer #dermatologist #melanomaawareness
