Symptoms Of Seborrheic Keratosis: Causes & Treatment Options

Seborrheic keratosis is skin growth which appears similar to a mole or a wart. It is considered a common skin growth mostly occurring in older people over the age of 40 or 50 years. Seborrheic keratosis can occur anywhere on the body except the skin of palm and sole. Most often the lesions develop on head and neck region or on back and chest.

The skin growths are slightly elevated, feel rough or like a candle wax. The color may range from brown to black. Although seborrheic keratosis lesions appear as precancerous or cancerous skin lesions they are completely harmless.

People seek treatment for their unsightly appearance.

The exact cause of seborrheic keratosis remains eluded. It is present mostly in people with fair skin and people having family history of seborrheic keratosis. Besides familial origin, exposure to sun is also a leading factor for development of these harmless skin lesions.

Treatment is aimed at removing the lesions. Electrocautery, cryosurgery and laser are effective treatment modes. Several home remedies such as apple cider vinegar, cold compresses, etc can be used to remove the lesion. Once removed the lesions usually do not develop again at the same site.

But there is possibility that seborrheic keratosis may develop in other areas of body.

Causes And Risk Factors Of Seborrheic Keratosis

The exact etiology of seborrheic keratosis is not known. The harmless growth is formed by excess accumulation of normal skin cells. Seborrheic keratosis usually develops in middle age and older age, although sometimes the lesions can also develop in young people. Men and women are equally affected. It is more seen in people with fair skin and among people having similar skin growth in the family.

Seborrheic keratosis does not occur in children. It is not an infectious condition. The three most common risk factors for seborrheic keratosis are:

  • Family history of seborrheic keratosis. The skin condition is known to run in families. The risk tends to increase when one or more than one member of family has this unsightly but harmless skin lesion.
  • Exposure to sun for prolonged period of time is also suspected to cause this harmless growth. However, some researchers do not agree with this theory because the lesions are also present on certain unexposed areas of body.
  • They also arise during pregnancy indicating a hormonal role.

Seborrheic keratosis can develop in any part of skin, but usually the lesions develop on face, neck and head region or on chest and back. The lesions never develop in palm and sole. The lesions are slightly elevated from the normal skin surface. They appear rough to touch or may have waxy feel. In most cases the waxy feel is the distinguishing feature.
