Onychomycosis in a 10-Week-Old Infant

Onychomycosis in a premature infant caused by Candida tropicalis

“…Fungal nail infections are almost exclusively observed in adults and such infections in children are rare. The rarity of onychomycosis in children has been attributed to faster linear nail growth with subsequent elimination of the fungus 2 . In neonates, Candida species are abundantly present in their environment, 3 but they affect mainly the skin and mucosa, whereas the nails are usually spared, and solitary localized involvement of the nail plate is very rare.…”

“…According to Kurgansky and Sweren 2 , the youngest reported patient with onychomycosis was a 10‐week‐old infant. To our knowledge, our described case of onychomycosis in a 107‐day‐old infant represents the first known case of an isolated lesion of the nail plate without involvement of glabrous skin, caused by C. tropicalis in this age group.…”

Trichophyton rubrum onychomycosis in an 8-week-old infant

“…Earliest dermatophyte onychomycosis was reported in an 8-week old infant by Borbujo-Martínez. [12] Another case was reported by Kurgansky and Sweren [13] in a 10-week-old infant. Both cases reported only few nails involvement.…”

Rapid response of Trichophyton tonsurans‐induced onychomycosis after treatment with terbinafine

“…Another study found that 1.31% of 2576 children aged under 15 years had onychomycosis; T. rubrum was the most frequent pathogen (82.4%), followed by T. tonsurans (8.8%) and Microsporum canis (2.9%) 4 . The youngest affected child previously reported in the literature was 10 weeks old 5 . The speculated predisposing factors for onychomycosis in children include genetic susceptibility, trauma, hyperhydrosis of the palms and soles, poor personal hygiene, swimming habits, sports activity, contact with animals, a family history of tinea, and immunosuppression 1,6,7 .…”
