List the three most common types of acquired circumscribed hair loss in children. Alopecia areata, tinea capitis, and trichotillomania. Alopecia areata is thought to be an autoimmune disorder, whereas tinea capitis is a fungal infection of the scalp hairs. Trichotillomania is self-inflicted and shows an irregular pattern of hair loss. Scalp appearance is normal in alopecia areata and scaly in tinea capitis; trichotillomania is associated with petechiae. |
