Tinea capitis in Infant/Neonate
It presents as numerous scaly macules and patches of broken hairs and alopecia on the scalp. Some forms are predominantly scaly with little alopecia and may resemble seborrheic dermatitis. More severe forms are associated with inflammatory papules, pustules, and plaques as well as systemic symptoms (ie, fever and malaise).
Majocchi-like granulomas, deep ulcerated fungal infections, severe tinea capitis and corporis, and fungal nail involvement are characteristic of an inherited deficiency of CARD9 (caspase recruitment domain-containing protein 9), an inflammatory cascade-associated protein. The disorder is autosomal recessive and is most common in North Africa countries including Algeria, Morocco, and Tunisia. The infections usually begin in childhood and are caused by Trichophyton rubrum and Trichophyton violaceum. Lymphadenopathy, high IgE antibody levels, and eosinophilia are common, and the disorder can be fatal.
