I've noticed a dark patch of skin behind my left ear that started as a small spot and has grown to the size of a coin, kind of in the shape of a banana. There's also a similar dark area on my upper chest. Both began about a year ago and are growing slowly. There's no itching, but I'm a bit worried. What could this be?
