The lesion between the thumb and index finger is a fairly well demarcated, patchy eczematous dermatitis, also called nummular eczema, meaning coin shaped. It is a red, weepy, itchy dermatitis usually found on the extremities. Dermatitis consists of a spectrum of diseases from very mild annoyances with dryness and irritation, to a severe disabling condition. Dermatitis by itself means inflammation of the skin. Eczema refers to a red, denuded and weepy dermatitis normally with considerable complaints of severe itching.
