Boils

Birthmarks are abnormal skin discolorations in spots that are either present at birth or appear shortly thereafter. They can be flat or slightly raised from the skin. They can be any number of colors, including red, brown, black, tan, pink, white or purple. Birthmarks are generally harmless. There are two major categories of birthmarks: pigmented birthmarks and red birthmarks.

Pigmented Birthmarks can grow anywhere on the skin and at any time. They are usually black, brown or skin-colored and appear singly or in groups. They can be moles (congenital nevi) that are present at birth, Mongolian spots, which look like bluish bruises and appear more frequently on people with dark skin, or café-au-lait spots that are flat, light brown or tan and roughly form an oval shape.

Red Birthmarks (also known as macular stains) develop before or shortly after birth and are related to the vascular (blood vessel) system. There are a number of different types:

  • Angel kisses, which usually appear on the forehead and eyelids.
  • Stork bites, which appear on the back of the neck, between the eyebrows on the forehead, or on eyelids of newborns. They may fade away as the child grows, but often persist into adulthood.
  • Port-wine stains, which are flat deep-red or purple birthmarks made up of dilated blood capillaries (small blood vessels). They often appear on the face and are permanent.
  • Strawberry hemangiomas, composed of small, closely packed blood vessels that grow rapidly and can appear anywhere on the body. They usually disappear by age nine.
  • Cavernous hemangiomas are similar to strawberry hemangiomas but go more deeply into the layers of the skin. These can often be characterized by a bluish-purple color. They also tend to disappear naturally around school age.

Also known as skin abscesses, boils form as a result of a cut or break in the skin, which leads to a bacterial infection. They are characterized as a red, tender area with a painful, pus-filled center that can open spontaneously or by surgical incision. Some boils are caused by an ingrown hair. Others are caused by plugged-up sweat glands, such as some types of cystic acne. Anyone can get a boil. They grow quickly and are usually painful until they drain. However, left alone a boil will naturally come to a head and burst open, allowing the pus to drain and the skin to heal. People with weakened immune systems are more susceptible to boils than the general population.

Boils tend to occur on parts of the body that have hair or sweat glands and are exposed to friction, typically on the face, neck, armpits or buttocks. There are a variety of different types of boils:

Furuncle or Carbuncle. These abscesses are caused by the Staphylococcus aureus bacterium. A furuncle is an individual boil; carbuncles are deep clusters of boils that most often form on the back of the neck, shoulders or thighs.

Pilonidal Cyst. An infected hair follicle around the buttocks area caused by long periods of sitting. Pilonidal cysts almost always require medical treatment.

Hidredenitis Suppurativa. These are multiple abscesses that form from blocked sweat glands in the armpits or groin areas.

Cystic Acne. These boils are situated more deeply into skin tissue than the more superficial forms of acne. It typically occurs among teenagers.

Boils respond well to home remedies. To promote healing, apply heat to the boil in the form of hot soaks or compresses. Keep the area clean, apply over-the-counter antibiotics and then cover with gauze. Do not puncture or squeeze the boil because it can lead to further infection. If the boil does not go away within two weeks, is accompanied by a fever or is painful, contact your dermatologist. The doctor will clean, lance and drain the boil and prescribe an antibiotic to alleviate the infection.
