A skin rash or skin changes can appear with contact dermatitis in response to a skin irritant or may be related to a chronic condition like eczema. Lice infestations can cause intense itching and scratching, leading to skin redness or thickening. A suspicious mole is usually a single abnormal spot on the skin and is not caused by eczema, contact dermatitis, or lice. Likewise, an actinic keratosis is a single, raised irregular area of skin that may be precancerous. Your doctor can help you determine the cause of any worrisome changes in your skin.
While the list below can be considered as a guide to educate yourself about these conditions, this is not a substitute for a diagnosis from a health care provider. There are many other medical conditions that also can be associated with your symptoms and signs. Here are a number of those from MedicineNet:
Contact dermatitis is a rash that occurs after exposure to an irritant. Symptoms of contact dermatitis include a red, elevated rash at the site of contact with the irritating substance. Contact dermatitis treatment may involve creams, application of cool water compresses, and applying topical steroids.
Head lice infection is called pediculosis. Lice are parasites that feed on blood and can be found on the scalp and hair of infected people. Signs and symptoms of head lice infestation include a tickling sensation, itching, and sores on the head. Head lice may be eliminated with various over-the-counter shampoos and washing all clothing and bed linens in the hot water cycle. Combs and brushes should be disinfected, and the floor and furniture should be vacuumed.
Eczema refers to skin inflammation. There are many different types of eczema that produce symptoms and signs that range from oozing blisters to crusty plaques of skin. Treatment varies depending upon the type of eczema the person has.
Actinic keratoses are rough, scaly patches of skin that are considered precancerous and are due to sun exposure. Prevention is to cut sun exposure and wear sunscreen.
