Itchy Rash on Legs?

Types of skin diseases that manifest on the legs.
Rash and eruptions on the leg are very common. They can occur as an isolated phenomenon, or as part of the skin disease of the body. Some of the common conditions , which come with itching and scaling on legs, are:

Eczemas –
There are several different types of eczemas, but one variety which is seen only on the legs and very rarely elsewhere on the body, is neurodermatitis. In this condition, there is a persistent dry patch mostly around the ankles, which itches especially at night or whenever the patient is sitting idle. It is a psychosomatic condition, which often comes when the patient is under stress. In such cases, making a conscious effort not to scratch and lubricating the patch liberally provides relief from itching.

Another common cause of eczema on the lower legs is varicose veins. Varicose veins are enlarged, twisted veins that appear near the surface of the skin and are caused by weakening of the vein valves. Eczema due to varicose veins causes the legs to appear dry, red and scaly. Apart from moisturisers, support stockings may be required in such cases.

Lichen Planus –
Lichen Planus is another chronic skin disease commonly found on the legs and is caused by an abnormal immune reaction provoked by a viral infection. It appears as small violet coloured bumps, which are extremely itchy. These eruptions often form raised and thick plaque-like eruptions, which can be very unsightly in their appearance. The disease may come in episodes lasting for six to nine months and often re-occur . Lichen Planus can persist longer in people who are severely affected. Along with treatment , it’s important to provide relief from itching and improve the appearance of the skin.

Ichthyosis –
Also known as fish skin disease, Ichthyosis is an inherited skin disorder that causes dead skin cells to accumulate in the form of thick dry scales on the skin’s surface. It is caused by an abnormality in the normal lifecycle of the skin. While in most people the growth, dying and shedding of skin happens unnoticed; people with Ichthyosis reproduce new skin cells at a faster rate than they can shed it. Symptoms usually worsen or are more pronounced in cold and dry environments and tend to improve during summer. People with Ichthyosis need to bathe, moisturise and exfoliate their skin on a daily basis.
