For a while now I've had brown patches of skin on my stomach that are very dry. The largest one is about 1 inch by 3 inches and starts on my chest and goes towards my belly button. I also have patches on my underarms and on the sides of my stomach. They don't itch, but they keep growing larger. I've tried lotion and scrubbing them off, but they come back. How do I get rid of them? Is it eczema or something else that I need to see a dermatologist for?
It's light brown, kind of wrinkly I guess, and is scaly.
