Dermatophytosis, or ringworm, is a fungal infection of the skin caused by dermatophytes, a type of fungi. These fungi feed on keratin, the protein that makes up the outer layer of skin, nails, and hair. The infection is highly contagious and can be spread from person to person, from animal to person, or from object to person.
Diagnosis of dermatophytosis is usually made through a physical examination of the affected area. The doctor may also take a skin scraping or culture to confirm the diagnosis.
Differential diagnosis of dermatophytosis includes other fungal infections such as tinea versicolor, and bacterial infections such as impetigo.
Treatment of dermatophytosis is usually with antifungal medications, which can be applied topically or taken orally. Depending on the severity of the infection, the treatment may need to be continued for several weeks.
The prognosis for dermatophytosis is generally good with proper treatment. However, if the infection is not treated promptly, it can spread to other areas of the body and cause more serious complications.
