Dermatofibromas and Your Skin

Dermatofibromas are harmless round, red-brownish skin growths that are most commonly found on the arms and legs. Dermatofibromas contains scar tissue and feel like hard lumps in the skin.

The cause of dermatofibromas is not known.

What Are the Symptoms of Dermatofibromas?

The symptoms of dermatofibromas include:

  • A red, brown, or purple growth that can change colors over time
  • A growth that is as small as a BB pellet
  • Tenderness, pain, and itching; however, growths also can be painless
  • A dimple that appears when the growth is pinched

How Are Dermatofibromas Treated?

In most cases, there is no need to treat dermatofibromas. However, the growths can be removed surgically or can be flattened by being frozen with liquid nitrogen.

Epidermoid Cysts and Your Skin

Epidermoid cysts, also called sebaceous cysts, are benign (non-cancerous) skin cysts formed by an outpouching from the hair follicle. Most commonly, epidermoid cysts are found on the genitals, chest, and back; but, they also can occur in other areas of the skin.

What Are the Symptoms of Epidermoid Cysts?

In general, epidermoid cysts have a round appearance. A dark portion of the cyst is visible on the skin. If the cysts become infected, they will become red and tender. When the cysts are squeezed, they can produce a cheesy white discharge.

How Are Epidermoid Cysts Treated?

The effective treatment of epidermoid cysts requires that the sac of the cyst be completely removed. If the cyst is squeezed and the discharge is forced out without removing the sac, the cyst will return. Usually, a doctor will be able to remove the cyst by making only a small incision in the skin. Antibiotics may be prescribed to treat infected cysts.

Folliculitis and Your Skin

Folliculitis is an inflammation of the hair follicles. It can be caused by an infection in the hair follicles, by chemical irritation or by physical irritation (for example, shaving or friction from clothing). Typical body sites that are involved in folliculitis include the face, thighs, and scalp.

Folliculitis is more common in people who have diabetes. It also is more common in people who are obese or have compromised immune systems.
