Types of rashes that potentially affect the fingers and hands include atopic eczema, granuloma annulare and candidiasis, according to Web MD and Healthline. Atopic eczema commonly occurs on the hands and joints, including the elbows and the backs of the knees. This rash is characterized by patches of red, dry and itchy skin. Sometimes blisters form in the affected areas, according to Web MD.

Granuloma annulare often manifests as a small ring of hard, reddish bumps on the back of the hand. This may be accompanied by minor itching. Sometimes the rash consists of only one ring, while other times multiple rings appear. The cause of granuloma annulare is unknown, but most cases do not require treatment, as the rash does not cause intense irritation, according to Web MD.

Candidiasis of the skin tends to occur in areas in which the skin folds, such as between the fingers. This rash may appear as moist, white or red patches between the fingers, and it is frequently accompanied by itching and pain. Candidiasis of the skin is usually treated with a topical antifungal cream, notes Healthline.
