Tinea Capitis Caused by Trichophyton tonsurans That Responded to Fosravuconazole.

We herein report the first case of tinea capitis caused by Trichophyton tonsurans that responded to fosravuconazole (F-RVCZ). Clinical improvement was achieved within six weeks after the start of F-RVCZ therapy, and the hairbrush culture test was negative. After treatment discontinuation, no relapse of symptoms was observed, and subsequent hairbrush cultures remained negative. F-RVCZ has been suggested as a rapidly acting and effective therapeutic agent for tinea capitis caused by this infection. Treatment of tinea capitis requires oral antifungal therapy; however, side effects associated with long-term administration sometimes occur. Oral treatment with F-RVCZ was found to be effective and had the advantage of relatively few side effects.
