Morphology of lesions<unk>  <unk>  skin lesions first present as dull or purplish red, disc-shaped flat or raised and firm areas of skin. These lesions then develop increasing amounts of white, adherent scale. Finally, the lesions develop extensive scarring and/or atrophy, as well as pigment changes. They may also have overlying dried fluid, known as crust. On darker skin, the lesions often lose skin pigmentation in the center and develop increased, dark skin pigmentation around the rim. On lighter skin, the lesions often develop a gray color or have very little color change. More rarely, the lesions may be bright red and look like hives. Location of lesions The skin lesions are most often in sun-exposed areas localized above the neck, with favored sites being the scalp, bridge of the nose, upper cheeks, lower lip, and ear and hands 24% of patients also have lesions in the mouth (most often the palate), nose, eye, or vulva, which are all mucosal parts of the body. More rarely, patients may have lesions on the head and neck as well as the arms and trunk. Special characteristics of some lesions Scalp lesions When<unk><unk>  is on the scalp, it starts as a red flat or raised area of skin that then loses hair and develops extensive scarring. The lesions often lose skin pigment and become white with areas of increased skin pigment, with or without areas of redness, and have a sunken appearance. They can have a smooth surface or have visible, dilated hair follicles on the surface. Lip lesions When<unk><unk>  is on the lip, it often has a grey or red colour with a thickened top layer of skin (known as hyperkeratosis), areas where the top layer has worn away (known as erosion), and a surrounding rim of redness. Other symptoms Patients may state that their lesions are itchy, tender, or asymptomatic. In addition to their skin lesions, they may also have swelling and redness around their eyes, as well as blepharitis. Complications Darker-skinned patients are often left with severe scarring and skin color changes even after the lesions get better. In addition, these patients have an increased, though still small, risk for aggressive skin squamous cell carcinoma.
