Blotches of dark skin that have a strange texture (dry, rough,flakey) all over my stomach and a little on my arm for a year. not itchy, but is ugly?

Tinea corporis: is most likely, although a picture would be helpful. Tinea is a fungal (yeast) infection of the skin that causes hyperpigmented (dark), scaly blotches that itch. Tinea tends to itch more when a person gets hot and/or sweaty, as the fungus thrives in a warm, moist environment. Tinea can be treated with antifungal creams and/or medication by mouth.
