A Filipino woman in her forties had facial erythema that was being self-treated with over-the-counter (OTC) drugs purchased outside of Japan. The drugs included clobetasol propionate, antibiotic, and antifungal components. Her facial erythema symptoms were worse during summertime. KOH direct examination of annular erythema was positive for fungal hyphae and negative for Demodex folliculorum. Fungal culture revealed Trichophyton indotineae based on internal transcribed spacer sequence analysis. Minimal inhibitory concentration for terbinafine was 0.06 µg/mL. We made a diagnosis of tinea faciei with steroid rosacea. We treated the patient with oral itraconazole. Physicians should be aware of increasing T. indotineae infections and increasing self-medication using topical OTC steroids combined with antifungals and antibiotics not only in India but also among foreign people living in other countries such as Japan.
