What does tinea capitis refer to?

Tinea capitis refers specifically to a fungal infection of the scalp. This condition is caused by dermatophyte fungi and is characterized by symptoms such as itchy, flaky, or scaly patches on the scalp, which may lead to hair loss in the affected areas. The term "tinea" denotes fungal infections, while "capitis" specifically indicates the involvement of the head or scalp.

While other conditions listed may involve fungal infections, they are not representative of tinea capitis. For example, fungal infections of the nails would be termed tinea unguium, ringworm can affect various parts of the body including the scalp but is a broader term, and jock itch (tinea cruris) specifically pertains to fungal infections of the groin area. Therefore, the most precise definition for tinea capitis is a scalp infection, as it directly indicates the location and type of fungal infection present.
