L85.9: Epidermal thickening, unspecified

Epidermal thickening (unspecified) is a skin condition where the outermost layer of the skin, known as the epidermis, becomes thicker than normal. The skin is composed of multiple layers, and the epidermis is its protective barrier. Sometimes, due to various factors like inflammation or an irregular cell production, this layer can become excessively thick. The condition may present itself in various forms such as rough, hardened skin or skin with a leathery texture. Some people may notice their skin has become thicker and harder in certain areas, or that it appears inflamed or discolored. Epidermal thickening isn't a specific disease, but rather a symptom or result of another skin condition or trauma. It can occur anywhere on the body and can be temporary or permanent depending on the cause. In general, it's a reaction of the body trying to protect itself, either from repeated irritation, pressure, or injury.
