Managing Discoid Eczema

What is discoid eczema?

It is a kind of chronic dermatitis. In this condition a red coin-shaped rash appears on the skin on different parts of the body like forearms, lower legs, feet, hands, trunk, etc. but not on the scalp or face. These round plaques consist of many tiny red spots and have a well-defined edge. Their size can vary from some millimeters up to a few centimeters.  The condition is also known as nummular eczema or dermatitis or discoid dermatitis. The term nummular came from the Latin word nummus which means coin; since this is a coin-shaped rash, therefore, it has been named so. The condition is extremely uncomfortable and itchy. It is not contagious, but people suffering from discoid dermatitis have high chances of developing other kinds of dermatitis.

This condition is more common in winter when the humidity levels drop. Nummular eczema is very rare in children and is more common in males between the ages of 60 to 70 years. Around 5.5% of the adult population in the USA suffers from constant eczema problem, which comes to approximately 15 million people.


Discoid dermatitis can either be dry or wet. In the dry state, the patches are red scaly and cracked while in the wet condition the patches are in the form of small bumpy fluid-filled sacs that ooze out liquid puss. The wet condition is very itchy, and once the fluid dries, it forms a crust. Usually, at first, the patches are dry but then turn wet and oozy.
