Trichophyton rubrum Infection in a 3‐Dav‐Old Neonate

Abstract

Trichophyton rubrum infection on the face of a 3‐day‐old neonate is reported because of its rarity.

Tinea faciei starting at day two of life

“…To our knowledge, our case developing at day two of life is the earliest reported occurrence of tinea faciei documented in the U.S. literature. Two cases with a similar onset have been reported in India …”

“…Although it is a common condition in pediatric patients, tinea faciei is rare in neonates with only a few reported cases in the United States . The majority of reported cases have occurred in India, likely due to the predilection of dermatophytes for warm and humid climates …”

“…[1][2][3] The majority of reported cases have occurred in India, likely due to the predilection of dermatophytes for warm and humid climates. [4][5][6][7][8][9] The incubation period for dermatophyte infections has been reported to be one to 3 weeks. 8 To our knowledge, our case developing at day two of life is the earliest reported occurrence of tinea faciei documented in the U.S. literature.…”

“…Two cases with a similar onset have been reported in India. 6,9 Several proposed mechanisms could account for the rarity of dermatophyte infections in neonates. Due to the presence of maternal androgens at birth, neonatal skin has a high concentration of sebum, which has antifungal properties and provides a physical barrier that protects skin from infections.…”

Tinea Faciei in a Newborn: A New case

“…The etiologic agent depends on the geographic area: Microsporum canis is the most common worldwide (2,4,7), whereas Trichophyton rubrum and T. mentagrophytes are frequent in Japan (4,10). T. tonsurans is the most frequently isolated agent of tinea faciei in the United States (3).…”
