What is Nummular Eczema (Discoid Eczema)?

Nummular eczema (discoid eczema) is a chronic type of eczema with coin-sized (1-10 cm), round or oval, sharply demarcated plaques. Lesions are often erythematous, vesicular, exudative (oozing), or crusted.

It most commonly involves the lower legs and dorsum of the hands; it is more common in men than in women. It tends to develop on a background of dry skin and atopy. Flares are common in winter months.

Differentiation from tinea corporis, psoriasis, and contact dermatitis is important. It can respond to treatment, but recurrences are frequent.
