What is nummular eczema?

ANSWER

"Nummular," the Latin word for "coin," refers to the coin-shaped spots on the skin that characterized this form of eczema. It’s also called discoid eczema because the scaly patches look like discs. Its cause is unknown, although the spots, which can be dry and scaly or weeping (and may or may not be itchy) might be triggered by reactions to inflammation or dry skin. The lower legs, forearms, and trunk are the most commonly affected areas.
