Cellulitis – Definition

Cellulitis refers to an infection of the skin and tissue just below the skin. The infection may occur anywhere on the body. It is most common on the lower legs.

Cellulitis – Causes

Cellulitis is often caused by a bacterial infection. It may come from bacteria that normally lives on the skin or bacteria from other sources. The bacterial infection may be caused by:

  • A minor injury to the skin (eg, cut, scratch, blister, burn, puncture, or bite) that becomes infected and spreads into the surrounding skin
  • Injuries that occur in natural bodies of water that become infected with germs found in the water
  • A cut or abrasion that becomes infected by food bacteria while handling fish, poultry, eggs, or meat
  • Bacteria that enter the body through surgical wounds or a catheter in a vein
  • Bacteria spreading from an upper respiratory or ear infection

Burns – Definition

A burn is damage to the skin and sometimes to the underlying tissues. Burns are categorized according to the depth and extent of the damage to the skin:

  • Superficial burn (also called first-degree burn)
    • Mildest type of burn
    • Often caused by ultraviolet light, or very short (“flash”) flame exposure
    • Affects only the outer layer of the skin (epidermis)
    • Normally does not cause scarring
    • Takes about 3-6 days to heal
  •  Superficial partial-thickness burn (also called second-degree burn)
    • Often caused by a scald (spill or splash) or short (“flash”) flame exposure
    • Affects the outer layer of the skin more deeply, usually causing blistering
    • May or may not cause scarring, but often does cause long-term skin color changes
    • Takes about 1-3 weeks to heal
  • Deep partial-thickness burn (also called second-degree burn)
    • Often caused by a scald (spill), may involve flame, oil, or grease
    • Affects the outer and underlying layer of skin (dermis), causing blistering
    • Usually causes scarring
    • Usually takes more than three weeks to heal

Boil – Definition

A boil is a red, swollen, painful bump under the skin that is caused by an infection. Boils often start in an infected hair follicle. Bacteria form an abscess or pocket of pus. Eventually, the pus may come to a head and drain out through the skin. Boils can occur anywhere, but common sites include the face, neck, armpits, buttocks, groin, and thighs.

There are several types of boils:

  • Furuncle or carbuncle — an abscess caused by the bacteria Staphylococcus aureus or Streptococcus pyogenes, sometimes occurs as several boils in a group
  • Pilonidal cyst — an abscess that occurs in the crease of the buttocks almost always require medical intervention
  • Cystic acne — an abscess that occurs when oil ducts become clogged and infected, more common in the teenage years
  • Hidradenitis suppurativa —an uncommon disorder where multiple abscesses occur in the armpit and groin area
