Nummular dermatitis: Overview
Also called discoid eczema
People who get this skin problem often see distinct, coin-shaped (nummular) or oval sores on their skin. Nummular dermatitis often appears after a skin injury, such as a burn, abrasion (from friction), or insect bite. A person may see 1 or many patches. These patches can last for weeks or months.
Your dermatologist may refer to this skin condition as:
- Nummular dermatitis.
- Nummular eczema.
- Discoid eczema.
Men get nummular dermatitis more often than women get it. Men often have their first outbreak between 55 and 65 years of age. When women get it, they are usually younger. They tend to be teenagers or young adults.
