Patients with fungal infections in the ear usually have fluffy discharge that can appear in various colors, including white, off-white, black and gray, as an article in American Family Physician explains. The most common fungal infections in the ear are Aspergillus and Candida, which both alter the ear canal's flora. In addition to itchy ears and discharge, patients with fungal infections also experience discomfort, feelings of fullness in the ear and tinnitus.

Psoriasis is a skin disorder that produces a pink or red rash covered with scales, according to Cleveland Clinic. The condition first presents itself as small red bumps that bleed when scratched. Other symptoms of psoriasis include itching, dry skin, skin pain and joint pain. These symptoms typically appear in early adulthood, and they commonly occur intermittently throughout a patient's life.

Dermatitis results from skin inflammation, and it occurs as either atopic dermatitis or contact dermatitis, as Cleveland Clinic explains. Irritation to the skin or a delayed allergic reaction cause contact dermatitis, and substances such as poison ivy, cosmetics, dyes, nickel, soaps and waxes can aggravate the condition accordingly. Patients with contact dermatitis experience redness of the skin, oozing blisters, intense itching and stiff skin. Atopic dermatitis is common in patients who have a family history of allergies, and it causes symptoms such as skin rashes, thickened skin and dry patches on the skin.
