The authors report the first case of dermatophytosis caused by Trichophyton raubitschekii in a patient from the State of São Paulo with Tinea corporis lesions localized on the buttocks. Culture on Sabouraud-agar with cycloheximide permitted the isolation and identification of the fungus, and the diagnosis was confirmed by Dr. Lynne Sigler, University of Alberta, Canada. Systemic treatment with fluconazole, 150 mg/week for 4 weeks, in combination with topical treatment with isoconazole initially yielded favorable results, with recurrence of the lesions after the medication was discontinued. This is the fifth case of this dermatophytosis published in the Brazilian medical literature.

Background: The widespread occurrence of chronic and recurrent dermatophytosis has significantly affected the quality of life for patients in India and beyond. Identifying the causative dermatophytes and understanding their antifungal susceptibility can aid clinicians in tailoring effective antifungal therapies.
Materials And Methods: Patients with chronic and recurrent dermatophytosis were enrolled, and conventional fungal cultures were conducted on skin scrapings.

Tinea blepharociliaris is a rare dermatophyte infection affecting the eyelashes and eyelids, often misdiagnosed as blepharitis, eczema, or bacterial infection, leading to ineffective treatments and recurrent symptoms. We report a case of a 10-year-old girl with erythematous plaques and fine scaling on the eyelids and eyelashes, initially suspected to have facial tinea or contact dermatitis. Direct mycological examination confirmed the presence of fungal filaments and spores, with culture identifying as the causative organism.

Background: Dermatophytes, the primary causative agents of superficial cutaneous fungal infections in humans, present a significant therapeutic challenge owing to the increasing prevalence of recurrent infections and the emergence of antifungal resistance. To address this critical gap, this study was designed to investigate the antifungal potential of 3-benzylideneindolin-2-one against dermatophytes and assess its in vivo toxicological profile using brine shrimp and zebrafish embryo models.
Methods: The antifungal activity of 3-benzylideneindolin-2-one was evaluated against 30 clinical isolates of dermatophyte species, including Trichophyton mentagrophytes, Trichophyton rubrum, Microsporum gypseum, Microsporum canis, and Epidermophyton floccosum, by determining the minimum inhibitory concentration (MIC) and minimum fungicidal concentration (MFC) using the broth microdilution method.

Background: Interdigital tinea pedis is a common type of tinea pedis that occurs between toes and is easy to recur. Recently, the skin microbiome analysis of interdigital tinea pedis showed changes in bacterial microbiome in addition to fungal infection.
Objectives: To investigate the efficacy and safety of clioquinol 3% cream in treating interdigital tinea pedis as well as characterize changes in the skin microbiome during treatment.
