A number of skin disorders can cause itching, which is also called pruritus. Eczema, a condition characterized by intense itching and red, flaky skin, is one of the most common causes of itchy skin.Dry skin and psoriasis -- a skin disorder that leads to red, scaly patches -- are also frequent causes of pruritus.uman immunodeficiency virus, or HIV, is another viral infection linked to pruritus.
