In Vitro Ravuconazole Susceptibility of Anthropophilic Dermatophyte Strains Isolated from Japanese Patients.

Ravuconazole (RVCZ) is a new human anti-fungal azole drug available in Japan since 2018 and is a broad-spectrum agent that exhibits excellent activity against dermatophytes. In the present study, the in vitro RVCZ susceptibility of clinical isolates of anthropophilic dermatophytes, including Trichophyton interdigitale strains with either low susceptibility to itraconazole (ITCZ) or resistance to terbinafine (TEBR), was investigated using the Clinical & Laboratory Standards Institute M38-A2 test. The MICs of RCVZ for 20 clinical isolates of T.

A Giant Dermatophyte Abscess Caused by Trichophyton rubrum in an Immunocompromised Patient.

A 73-year-old male who had been receiving immunosuppressive drugs for 15 years developed a nodule on the left buttock region. The nodule slowly grew into a 15-cm fluctuant multilocular subcutaneous cyst. Serum beta-D-glucan levels were high, and the yellow purulent fluid obtained from the cyst was positive for Trichophyton rubrum.

Treatment Outcomes for Malassezia Folliculitis in theDermatology Department of a University Hospital in Japan.

Topical or systemic antifungal therapy was administered to patients diagnosed with Malassezia folliculitis during the 5-year period between March 2007 and October 2013. The diagnosis of Malassezia folliculitis was established on the basis of characteristic clinical features and direct microscopic findings (10 or more yeast-like fungi per follicle). Treatment consisted of topical application of 2% ketoconazole cream or 100 mg oral itraconazole based on symptom severity and patients' preferences.
