Although tinea capitis is common in children, but it is rare in newborns. It should be differentiated with neonatal lupus erythematosus, nummular eczema, psoriasis, seborrheic dermatitis, erythema annular centrifugum, annular urticaria, and annular erythema of infancy. Tinea capitis usually needs oral antifungal therapy, but the data of use in newborn is limited. Here, we report a case of tinea capitis caused by Microsporum canis in a 23‐day‐old female newborn. The patient was given itraconazole oral solution pulse therapy with an excellent outcome. Itraconazole oral solution pulse therapy may be a promising therapy for tinea capitis in infants, especially in newborns.
Case presentation A 6-month-old girl presented with 4 weeks history of rapid growing scalp erythema with multiple pustules, purulent secretions and alopecia (Figure 1a). Her father, mother, grandfather and grandmother suffered from tinea corporis in succession 2 months ago. Direct fungal microscopic examination revealed numerous endothrix spores (Figure 1b), and cultures grew Trichophyton tonsurans (Figure 1c). She was treated with oral fluconazole 50 mg/d (6 mg/kg/d) and 2% ketoconazole cream for 8 weeks with complete remission of the lesions (Figure 1d). Discussion Tinea capitis is a common dermatophyte infection of the scalp and hair follicles, predominantly occurring in children between 3 and 7 years of age, but is uncommon in the first year of life
