Dermatophytosis, also known as ringworm, is a fungal infection of the skin, hair and nails caused by dermatophytes. It is one of the most common skin conditions in the world and can affect people of any age.
Diagnosis of dermatophytosis is usually made by physical examination and clinical history. A skin scraping or biopsy may also be taken and examined under a microscope.
Differential diagnosis includes other fungal infections such as tinea versicolor, seborrheic dermatitis, psoriasis, and atopic dermatitis.
Treatment of dermatophytosis usually consists of antifungal medications such as topical creams, lotions, shampoos or oral medications.
The prognosis for dermatophytosis is usually good with proper treatment. In some cases, the infection may recur and require repeated treatments.
