Abstract

reported. C. tropicalis is often isolated from fungus-infected nails in Brazil, but there have been no reports of onychomycosis caused by C. tropicalis in Japan. The risk factors of candidal onychomycosis include congenital mucocutaneous candidiasis, HIV infection, immunosuppressive therapy, peripheral vascular disease and diabetes mellitus. Trauma during farming or hobby gardening may contribute to the onset of finger onychomycosis, whereas no significant risk factor was identified in the patient in the present case. The association of chronic paronychia suggests the involvement of Candida; however, candidal infections are difficult to diagnose in cases without swelling of the nail fold. Although a fungal culture is the gold standard for identifying the causative organism, this examination requires several weeks of incubation and sometimes produces a false-negative result. In addition, several strains of Candida species demonstrate resistance to terbinafine. Therefore, azoles, including itraconazole and fosravuconazole, which exhibit remarkable antifungal activity against Candida species, should be preferentially prescribed to patients with finger onychomycosis.
