Complications of Dermatophytosis

Dermatophytosis, commonly known as ringworm, is a fungal infection that primarily affects the skin. While it is generally a mild condition, complications can arise if left untreated or if the infection spreads to certain areas of the body.

1. Spread to the Scalp

One of the potential complications of dermatophytosis is its spread to the scalp. When the fungus affects the scalp, it can lead to a condition called tinea capitis. This can cause severe itching, redness, and the development of patches or areas of hair loss. Treatment for scalp dermatophytosis usually involves oral antifungal medication to eradicate the fungus from the hair follicles and prevent further hair loss.

2. Secondary Infections

If the skin affected by dermatophytosis becomes severely inflamed and itchy, scratching can lead to breaks in the skin. This creates an opportunity for bacteria to enter and cause a secondary infection. These secondary infections can be painful and may require additional treatment, such as antibiotics, to clear the infection and promote healing.

In some cases, dermatophytosis can also cause a condition known as eczema herpeticum. This occurs when the herpes simplex virus infects areas of the skin already affected by dermatophytosis. Eczema herpeticum can lead to painful blisters and requires immediate medical attention.

In conclusion, while dermatophytosis is generally a mild condition, it can lead to complications if left untreated or if the infection spreads. Proper treatment and management can help alleviate symptoms and prevent complications such as spread to the scalp and secondary infections.

When to See a Doctor
