Question: what are the white spots on my ear?
Answer: Chondrodermatitis nodularis helicis (CNH) is a skin condition that affects the cartilage of the ear. It's a painful nodule, which may or may not have a scab on it, that grows over a period of time. The nodule grows quickly, typically measuring between 2 and 4 millimeters, and then stops growing, but remains persistent.
