How to Treat Epidermal Nevus?

What Is Epidermal Nevus?

Epidermal nevus, also known as epidermal nevus syndrome (ENS) or nevus sebaceous, is a relatively rare skin disorder that is typically present from birth or develops in early childhood. These nevi are characterized by the presence of raised, wart-like growths or patches on the skin's surface. The term "nevus" refers to a mole or skin blemish, while "epidermal" relates to the outermost layer of the skin, known as the epidermis. These growths can manifest in various sizes and appearances, often appearing as brown, tan, or pinkish patches with a rough, warty texture.

Epidermal nevi can occur on any part of the body, and their size, shape, and distribution can vary widely among affected individuals. 

Why Do Epidermal Nevi Occur?

Epidermal nevi are primarily the result of genetic mutations that lead to an overgrowth of the epidermal cells in the skin. These mutations are typically not inherited from parents but rather occur spontaneously during early fetal development. This means that epidermal nevi are not usually passed down from generation to generation.

During embryonic development, genetic mutations can affect the development of the epidermis. These mutations cause the epidermal cells to proliferate excessively, resulting in the formation of epidermal nevi. The exact cause of these mutations is not always clear, and there is often no specific trigger for their occurrence.
