It is a chronic discoloration of the skin which usually affects the legs and often spreads slowly.
cause- leaky blood vessels near the surface of the skin, capillaries, which allow red blood cells to slip through into the skin. The red blood cells in the skin then fall apart and release their iron which causes a rust color, this accounts for the orange tint of the rash
symptom- lesions are most frequent on the lower limbs
, but may occur anywhere on the body, including the hands, arms, torso and even the neck. They may vary in number and erupt in mass numbers. They consist of irregular patches of orange or brown pigmentation due to hemosiderin
(iron), with characteristic "cayenne pepper" spots appearing within and at the edge of old lesions. There are usually no symptoms, although there may be some slight itching. No other significance.
No treatment required for it however vitamin supplement can be given.
so you need not to be worried at all.
