<p>Updates on Genital Dermatophytosis</p>

Abstract

Dermatophytes are a group of keratinophilic fungi, which normally cause superficial infection of skin, hair and nails. Based on ecology, they are classified into three groups: anthropophilic, zoophilic and geophilic. Superficial dermatophytic infection of the genital region is called genital dermatophytosis, tinea genitalis or pubo-genital dermatophytosis. In this review, we would like to discuss briefly, the various clinical presentations of genital dermatophytosis, current changes in the taxonomy and nomenclature, introduction of new diagnostic techniques and briefly describe some common dermatophytes and their sources. Also, there are serious concerns associated with the recent development of antifungal resistance among the dermatophytes. We are also facing the scenario of hard-to-treat dermatophytosis.

Aetiology of tinea of vellus hair and substrate specificity in Microsporum species

“…Vellus hair is predominantly distributed over the glabrous skin, such as face, trunk and limbs. [2][3][4] In case of tinea of vellus hair, the hairs are affected by hypha and/or spores internally and on the outside, and concomitant-localised skin infection can be observed. Despite the widespread presence of vellus hair on the human body, limited data is available regarding the epidemiology of vellus hair infection, compared to that of the more pronounced presence of tinea capitis; tinea of vellus hair has, therefore, long been regarded as a rarely encountered clinical entity.…”

“…In contrast, vellus hair is fine and soft, with light pigmentation. Vellus hair is predominantly distributed over the glabrous skin, such as face, trunk and limbs 2–4 . In case of tinea of vellus hair, the hairs are affected by hypha and/or spores internally and on the outside, and concomitant‐localised skin infection can be observed.…”

Clinical Characteristics and Pathogen Spectrum of Male Genital Fungal Infections in Nanchang Area, South China

“…By the routine detection of fungal infections, we often found that some patients were positive for fungal infections in scrapings from scrotum by direct microscope, but showed no clear clinical features of fungal infections. In addition, the dominant etiology of fungal infections on male genitalia varied in different regions [ 14 ], and most of clinical manifestations were also different from tinea corporis and tinea cruris [ 4 , 5 , 9 – 12 ]. Therefore, it is necessary to perform comprehensive analyses of cutaneous fungal infections on male genitalia.…”
