tinea capitis

Tinea capitis, commonly known as ringworm of the scalp, is a superficial fungal infection caused by dermatophytes. These fungi feed on keratin, a protein found in skin, hair, and nails. The infection typically manifests as round or ring-shaped lesions on the scalp. These lesions can be dry and scaly or may present with blisters, depending on the specific fungus and affected area.1

In children, tinea capitis is a common fungal infection. It can lead to hair loss in the affected areas and may be characterized by "black dot" ringworm, where hairs break off at the scalp surface. Diagnosis is usually made through visual inspection and microscopic examination. Treatment often involves topical or oral antifungal medications.21
