Synopsis

Nummular dermatitis is a form of dermatitis characterized by coin-shaped, scaly plaques. While generally a disease of adults, the peak age of childhood nummular dermatitis is 5 years. It is of uncertain etiology, but it is associated with triggers such as frequent bathing, low humidity, irritating and drying soaps, and exposure to irritating fabrics such as wool. Patients often have some of the signs and symptoms typically associated with atopic dermatitis. Pruritus can be severe, and affected children can be irritable.

Winter is usually the time of onset and exacerbation. Nummular dermatitis can be chronic with a waxing and waning course.

Some experts consider childhood nummular dermatitis as a subtype of atopic dermatitis.
