“… 19 One study even used MALDI-TOF MS strategy combined with the traditional methods to identify T. benhamiae . 40 However, lack of complete databases of filamentous fungal species and standardized procedures limit the practicality of MALDI-TOF MS in dermatophyte detection.…”

Impetigo, commonly caused by bacteria, is characterized by lesions of pustules, bullae or golden yellow crusts; it is seldom caused by fungi. Here, we report one case of a 17-year-old female patient with a 1-month history of erythematous pustules on her left cheek. She was clinically diagnosed with “impetigo”, but did not respond to 1 week of treatment with topical mupirocin cream (antibacterial agent). We then saw that a fungal colony grew on the culture, which was identified as T. mentagrophytes based on the morphological and molecular characteristics. The patient was then diagnosed with tinea faciei and was topically treated with 0.2% ketoconazole cream twice per day for 7 days. Through a literature review, we found another 18 cases of impetigo-like tinea faciei with similar clinical manifestations and pathogenic characteristics. Among these, the most common causative agent was T. mentagrophytes complex, which frequently occurs in children and adolescents and exhibits no gender preferences. Systemic and topical antifungals such as terbinafine or itraconazole are effective for impetigo-like tinea faciei caused by T. mentagrophytes complex. However, prolonged course of impetigo in more than 50% cases highlights the importance of mycological examination when dealing with apparent antibiotic-resistant impetigo cases in clinical settings.

“…Trichophyton benhamiae is a zoophilic dermatophyte 1 that causes inflammatory fungal infections frequently affecting the skin and scalp. 2 It is considered an emerging mycosis 2,3 and its presence has been reported in Asia, America and Europe. [4][5][6] T. benhamiae infection is associated with contact with domestic animals such as guinea pigs, rabbits and dogs.…”

“…Among these, T. benhamiae has two phenotypic variants: one with white colonies (T. benhamiaae var benhamiae) and the other with yellow colonies (T. benhamiae var luteum) 7,8 which could be confused with T. mentagrophytes and M. canis, respectively. 3,9 The micromorphology shows hyaline septate hyphae, few to many pyriform microconidia on sessile or clustered arrangements; macroconidia and spiral hyphae may be few in white variants and absent in yellow variants. Morphological identification of T. benhamiae is not sufficient and species identification requires genomic or proteomic analysis.…”

is an emerging zoophilic dermatophyte that mainly infects skin and scalp and has been reported in Asia, America and Europe. It has two phenotypic variants: one with white colonies and the other with yellow colonies. Morphological identification of is not sufficient and can be confused with or . Genomic or proteomic analysis is required to establish a definitive identification. We present three dermatophyte strains obtained from the skin, nails and scalp of human infections in which macroscopic and microscopic examinations were not sufficient to identify the species. The final identification of was performed using MALDI-TOF mass spectrometry. This is the first report of in Peru.

“…It is mostly transmitted from guinea pigs, although transmission from cats, dogs, rabbits, rodents, and hedgehogs has also been reported. 1,2 Its incidence is probably underestimated because of its macroscopic and/or microscopic similarity with other dermatophytes (mainly other species of Trichophyton or Microsporum canis), which may lead to misidentification. 3 To avoid misdiagnosis, morphology cannot be used as the sole characteristic for classification or identification of dermatophytes.…”
