Nummular eczema is an allergy-related skin disorder causing characteristic itchy, coin-shaped lesions.

Eczema - nummular; Nummular dermatitis

The cause of nummular eczema is unknown, but there usually is a personal or family history of asthma, allergies, atopic dermatitis, or similar disorders. It is a relatively uncommon disorder that most often occurs in elderly men.

Eczema is generally a chronic, recurring condition. Exposure to environmental irritants may worsen symptoms, as can dryness of the skin, temperature changes, and stress.
