Subungual melanoma is a type of melanoma that forms under the nail bed, affecting either the toenails or fingernails
Have you ever noticed something unusual about your toenail? Perhaps a dark streak, an odd discoloration, or a change in texture that you can’t quite explain? While it might be tempting to dismiss these changes as a result of a recent pedicure or a minor injury, they could be warning signs of something more serious: subungual melanoma. This rare but potentially dangerous form of skin cancer develops under the nail bed and is often mistaken for benign conditions like toenail trauma or fungal infections. Understanding the signs, risk factors, and the importance of early detection could save your toe—or even your life.
