Which condition is associated with a fungal infection characterized by yellow crusts on the scalp?

1. Folliculitis

2. Scalp psoriasis

3. Tinea favosa

4. Contact dermatitis

The correct answer is: Tinea favosa

The condition characterized by a fungal infection and the presence of yellow crusts on the scalp is tinea favosa. Tinea favosa, also known as favus, is caused by the fungus Trichophyton schoenleinii. It manifests as inflammatory lesions that can lead to scarring and hair loss if left untreated. The yellow crusts observed in this condition are a result of the fungal infection and the body's inflammatory response. On the other hand, folliculitis is an inflammation of the hair follicles usually caused by bacteria rather than a fungal infection and does not typically present with yellow crusts. Scalp psoriasis is an autoimmune condition that leads to red, scaly patches on the scalp rather than crusts, and while it can appear yellowish, it is not due to a fungal infection. Contact dermatitis arises from a reaction to irritants or allergens, presenting with redness and possibly blisters, rather than a fungal infection with yellow crusts. Understanding these distinctions highlights why tinea favosa is the correct answer in this context, specifically relating to the symptoms of yellow crusts on the scalp due to a fungal cause.
