What skin condition is characterized by a fungal infection causing red, itchy patches?

The skin condition characterized by a fungal infection causing red, itchy patches is tinea, commonly referred to as ringworm. This condition is caused by dermatophytes, a type of fungus that thrives on keratin found in skin, nails, and hair. The presentation of tinea includes circular, red patches with clear centers, often accompanied by intense itching. These patches can occur on various parts of the body, including the scalp, feet, and groin, depending on the specific type of tinea involved.

Atopic dermatitis, on the other hand, is an inflammatory skin condition usually associated with allergies and characterized by chronic, itchy, and inflamed skin, but it is not caused by a fungal infection. Rosacea is a chronic inflammatory skin condition primarily affecting the face, resulting in redness, visible blood vessels, and sometimes acne-like breakouts, rather than patches. Dermatitis is a broader term that refers to inflammation of the skin and can be caused by various factors such as irritants or allergens, but does not specifically point to a fungal infection.
