What characterizes tinea capitis?

Tinea capitis is a fungal infection of the scalp, which is often characterized by red, inflamed spots or patches that can lead to hair loss in affected areas. The appearance of these red spots signifies an inflammatory response to the fungal infection, making it a key identifying feature.

In contrast, itchy patches on the feet are indicative of tinea pedis (athlete's foot), while fungal growth on the nails refers to tinea unguium or onychomycosis. Scaly skin on the body could be linked to various dermatological conditions including tinea corporis, but it does not specifically define tinea capitis. Therefore, the presence of red spots on the scalp aligns correctly with the clinical presentation of tinea capitis.
