Eczema is an umbrella term that includes atopic dermatitis, dyshidrotic eczema, asteatotic eczema, neurodermatitis, stasis dermatitis, contact dermatitis, and seborrheic dermatitis. While these are the most common forms, there are numerous other variants that fall under the term eczema.

Most eczema eruptions are red, itchy, and can be present with or without scales. Depending on the type of eczema, treatment can vary greatly. For instance, contact dermatitis is usually treated by topical steroid application and avoiding contact with whatever produced the rash. Stasis dermatitis, meanwhile, is often treated with compression therapy that involves wearing a tight-fitting material on the affected area to help reduce the swelling and poor circulation that prompted the condition.

It is easy to see that while very common, it is important to have eczema checked out by a specialist to avoid incorrect and potentially harmful home treatment. A trained clinician – like one of our staff – can spot the sometimes subtle variations between eczema types and prescribe the most effective regimen.


In normal skin, the body produces new skin cells at a certain rate that allows the newer cells to rise to the highest layers of dermis as the oldest cells are sloughed or flaked off. In psoriatic patients, the body sends incorrect signals to the skin that causes overproduction of skin cells. These cells are pushed to the outer layers of the skin quicker than normal, so they don’t look like normal skin. They are red and may appear either like plaques or pustules. They are often covered with a scaly, silvery crust.

While the precise cause of psoriasis is unknown, numerous treatments are available. These include topical steroids, treatments under special light boxes, and oral or injectable medications. It should be noted, however, that tanning salon beds are not appropriate treatment, as they type of light used in those machines contains a far more carcinogens than the medically formulated machines.

Psoriasis can occur anywhere on the body but is most frequently found on the elbows and knees. It is not contagious but can be both itchy, painful, and embarrassing. Since there are different types of psoriasis, it is crucial to get a professional evaluation and treatment plan.

Whenever a rash occurs, avoid trying to diagnose and treat it without having it assessed by an expert. Make an appointment and get the peace of mind that comes with knowing what the rash is and how to properly treat it.
