ABSTRACT
White superficial onychomycosis (WSO) is defined as fungal infection of the nail plate from dorsal surface of the nail plate. In English literatures, prevalence of WSO in the general population is about 1% to 2%, and the most common causative organism of WSO in adults is Trichophyton mentagrophytes except AIDS patients. On the other hand, the prevalence in children is 0.3%. A 6-year-old boy presented with whitish patches on his ten toe nails which had developed 4 years previously. He had cerebral palsy with spastic tetraplegia and epilepsy, and had admitted eight times for systemic infections, such as pneumonia and pharyngitis. Trichophyton rubrum was revealed as a causative organism by slide culture and PCR test. The nails showed improvement after two months of topical treatment with amorolfine nail lacquer. Herein we report a case of childhood multiple WSO caused by Trichophyton rubrum.
