dermatofytóz

Dermatophytosis, commonly known as ringworm, is a superficial fungal infection affecting the skin, hair, and nails. It is caused by a group of fungi called dermatophytes, which feed on keratin, a protein found in these tissues. Despite its name, ringworm is not caused by a worm, but by a fungus.

The infection typically appears as a circular, red, itchy rash with a raised border and clearer skin in the center. However, its appearance can vary depending on the location on the body and the specific dermatophyte involved. It can manifest as scaly patches, blisters, or cracked skin. Common sites of infection include the scalp (tinea capitis), feet (tinea pedis or athlete's foot), groin (tinea cruris or jock itch), and body (tinea corporis).

Dermatophytosis is contagious and can spread through direct contact with an infected person or animal, or indirectly through contaminated objects such as clothing, towels, or shower floors. It thrives in warm, moist environments.

Diagnosis is usually made based on the characteristic appearance of the rash. In some cases, a skin scraping may be examined under a microscope or sent for fungal culture to confirm the diagnosis and identify the specific type of fungus.

Treatment typically involves topical antifungal medications, such as creams, lotions, or powders. For more severe or widespread infections, or those involving the nails or scalp, oral antifungal medications may be prescribed. Good hygiene practices, such as keeping the skin clean and dry, are important for prevention and to avoid reinfection.
