Background: Superficial white onychomycosis is exceptional in children, although a few anecdotal cases have been reported in the literature. On the other hand, superficial white onychomycosis and proximal subungual onychomycosis, while unusual in the general population, often appear in adult human immunodeficiency virus (HlV)-infected persons.
Case report: A 3-year-old girl with vertically acquired HIV-1 infection presented superficial white onychomycosis involving the second, third, fourth and fifth toes of her left foot, caused by Trichophyton rubrum. She was treated with topical amorolfine once a week, with a good response within 4 weeks.
Conclusions: We report a case of superficial white onychomycosis associated with HIV infection in a 3-year-old girl. To our knowledge, this type of onychomycosis has not been previously reported in HIV-infected prepubertal children.
