Ringworm (Tinea Corporis)

Dermatophytosis, more commonly known as as ringworm, is a fungal infection of the skin. Ringworm is a misnomer. The infection isn’t caused by a worm. It’s caused by a fungus. Ringworm is a common fungal infection that appears on different parts of the body. It is characterized by ring-shaped, scaly and itchy patches of the skin. The patches may blister or ooze fluid.  Ringworm of the scalp is common in children, where it may cause bald patches. This is contagious and can be passed from person to person, by skin-to-skin contact, or through contact with contaminated personal care products, clothing or linens. Pets, particularly cats, can also pass on the infection.

The fungi are attracted to warm, moist environments, which is why the most common forms include:

  • Tinea Barbae, which occurs on bearded areas of the face and neck.
  • Tinea Capitus, which occurs on the scalp.
  • Tinea Cruris, also known as Jock Itch, occurs in the groin area.
  • Tinea Pedis, also known as Athlete’s Foot, occurs between the toes.

Ringworm generally responds well to home remedies and will disappear in about four weeks. In addition to keeping the area clean and dry, you can apply over-the-counter antifungal powders, lotions or creams. In more severe cases, your dermatologist may recommend prescription antifungal medications and antibiotics.
