Lichenoid keratosis is a benign skin lesion that appears as a small papule ranging from red to gray, often on areas exposed to sunlight. It affects fair-skinned and older people, especially women. Treatment includes medicated creams, liquid nitrogen, or surgical removal.
Lichenoid keratosis refers to a type of small, benign skin lesion. Other than the lesion on the skin, there are very few symptoms of this ailment. This lesion, sometimes referred to as a papule, can range from red to gray. Some people, such as women or the elderly, appear to be more at risk of developing this type of injury than others. Treatment for this condition may include medicated creams or surgery.
Keratin is a protein in the body that makes up a large part of a person’s hair, skin, and nails. It is also found in tooth enamel. When this protein is pushed to the skin surface of a person’s body, they die. A buildup of these excess dead keratin cells can lead to a hard or scaly lesion on the body. When this happens, it can resemble lichen, a type of crusty fungus often found growing on rocks and trees.
There are often very few reported symptoms of lichenoid keratosis. Some individuals may report an itchy sensation and some may experience a slight burning sensation. Skin lesion is usually the most common, and sometimes the only, symptom reported.
The lesions associated with lichenoid keratosis are usually quite small. On average, they usually grow to be no larger than 0.5 inch to 1 inch (1.3 to 2.5 centimeters). These lesions also have a tendency to form on areas frequently exposed to sunlight. They can often be found on a person’s torso or arms. In some cases, they can be found on the head, face or neck. Usually only one of these lesions will appear on a person’s body, but some people may have a couple more.
The skin lesions caused by this condition can vary in color. Many of them may appear red or pink at first. Others can be purple, brown or gray. They can also vary in texture. Some of them may be relatively smooth, for example, while others may be scaly.
Females are typically more at risk of developing lichenoid keratosis. In fact, some studies show that women are more than twice as likely to get these types of injuries. This skin disorder almost always affects fair-skinned and older people.
Treatment of lichenoid keratosis typically begins with a medicated topical cream containing corticosteroids. They can also be covered with liquid nitrogen. In some cases, surgical removal of the lesion may be necessary.
