Hyperkeratosis is the thickening of the outer layer of the skin due to an excess accumulation of keratin, a robust protein that forms a major component of the outer skin layer. This condition is commonly observed in localized areas and can manifest as corns, calluses, or warts. In rare cases, a hereditary form affects the entire soles and palms. Additionally, the term “hyperkeratosis” is also used to describe the thickening of the nails.
