There are a number of skin conditions that can present in this manner. You should see a dermatologist who can have it assessed. Dry skin and cracking and skin irritation tends to occur more frequently on the joints so this could also be a causes. However, certain autoimmune disorders and infections can cause these symptoms. With these diseases you would have also noticed some joint symptoms, like pain and swelling. A superficial infection may eventually affect the joint and lead to septic arthritis or spread throughout the body (septicemia). You need to see a doctor and have it assessed properly.
