Hyperkeratosis on Face Pictures - 3 Photos & Images
Hyperkeratosis is a thickening of the outer layer of the skin. This outer layer contains a tough, protective protein called keratin.
This skin thickening is often part of the skin's normal protection against rubbing, pressure and other forms of local irritation. It causes calluses and corns on face. It can cause whitish areas inside the mouth.
There are many examples of hyperkeratosis. They include:
- Warts. Warts are small bumps on the skin that are caused by human papilloma virus (HPV) infection. Plantar warts grow on the soles of the feet.
- Chronic eczema. Eczema is an inflammation of the skin. It can be triggered by allergies, irritating chemicals and other factors. Eczema is also called dermatitis. Eczema causes itching, redness and tiny blisters.
- Lichen planus. This condition may appear as a lacy white patch on the inside of the mouth. Or it may be an itchy, violet, scaly patch elsewhere on the skin. Lichen planus may be related to an abnormal reaction of the immune system.
- Actinic keratoses. These are flat, red, rough, sandpaper-like spots or patches of skin. They can be as tiny as a few millimeters. They are caused by excessive exposure to the ultraviolet radiation of sunlight. They occur on sun-exposed areas of skin. And they have the potential to develop into skin cancer.
- Seborrheic keratoses. These are small, noncancerous skin growths. They can be tan, brown or black. They appear on the face, trunk, arms or legs. Seborrheic hyperkeratoses are very common. Their cause is a mystery.
- Inherited conditions. Several inherited conditions cause hyperkeratosis. They cause a widespread, thick, platelike scaling of the skin. Symptoms begin either shortly after birth or during early childhood.
