Abstract
Superficial mycoses of skin, nails and hair are among the common fungal infections. They are caused by dermatophytes, non-dermatophyte moulds, yeasts and yeast-like fungi. Such fungal infections are widespread all over the world and are predominant in tropical as well as subtropical regions. Environmental factors, such as warm, humid and pitiable hygienic conditions, are conducive for their growth and proliferation. Although it does not cause mortality, it is known to be associated with excessive morbidity which may be psychological or physical. This affects the quality of life of the infected individuals which leads to a negative impact on their occupational, emotional and social status. Such infections are increasing on a global scale and, therefore, are of serious concern worldwide. This review article covers the global and Indian scenario of superficial mycoses taking into account the historical background, aetiological agents, prevalence, cultural and environmental factors, risk factors, pathogenesis and hygienic practices for the prevention of superficial mycoses.

Abstract
Tinea barbae represents a very rare dermatophytosis. We report on a tinea barbae profunda following a journey to Southeast Asia. After travel to Thailand, a businessman was affected by a foudroyant proceeding abscessing infection of the upper lip and beard area. The initial therapy with oral acyclovir and oral ciprofloxacin, which later was changed to ampicillin plus sulbactam, intravenously, was unsuccessful. In a biopsy sample, histologically, with Grocott-Gomori's methenamine silver stain, fungal mycelium was apparent in the tissue. Thereupon, terbinafine 250 mg was given for 4 weeks, topically, a 1% ciclopiroxolamine-containing cream. In fungal culture, T. mentagrophytes were found to grow. Meanwhile, the patient's German wife suffered from a tinea faciei. From skin scrapings from the cheek, T. mentagrophytes was also cultivated. This zoophilic dermatophyte was identical with other zoophilic strains of T. mentagrophytes currently found in Germany, which were also acquired in Thailand. The patient had contact with Thai female sex workers who must be considered as a source of infection of the dermatophytosis. There was no animal contact, neither in Thailand, nor in Germany. The infection chain of the dermatophytosis from Thailand probably reached from a female sex worker via the here described patient to his wife in Germany. This pathway of infection has been known for 1 or 2 years, but until now, in Germany, Switzerland, and Austria exclusively via pubogenital infections (tinea genitalis profunda) due to T. mentagrophytes after journeys to Southeast Asia. For treatment, oral antifungal agents should be used, first of all terbinafine, alternatively fluconazole or itraconazole.

Abstract
Tinea barbae is a rare dermatomycocis, by definition follicular bound in the beard area of adult men. Manifestation usually starts with erythema accompanied by desquamation. Deeper distribution along terminal hairs leads to folliculitis with formation of pustules and nodes as well as abscesses; fixed adherent yellowish crusts may appear. Frequently there is locoregional swelling of the lymph nodes and occasionally a deterioration of general condition with (sub)febrile temperatures. Often this leads to the initial suspected diagnosis of a bacterial folliculitis barbae or impetigo contagiosa. Tinea barbae is mostly induced by species of the genus Trichophyton (T.). The pathogens are diverse and are mostly zoophilic, sometimes anthropophilic and rarely geophilic dermatophytes. With the help of a specific anamnesis and diagnostic procedure, including mycological examinations, histology and molecular detection of dermatophytes via polymerase chain reaction (PCR), tinea barbae-in our patient induced by T. mentagrophytes-can be rapidly diagnosed. Early initiation and adequate treatment duration lead to restitutio ad integrum.

Abstract
Microsporum gypseum complex is a group of geophillic dermatophytes with a worldwide distribution and is a rare cause of dermatomycoses in humans. The infection most commonly presents as tinea corporis, with some geographical and occupational variations. We studied M. gypseum complex infections in patients examined in the Mycological Laboratory of the Department of Dermatovenereology, University Medical Centre Ljubljana, during the period 2000-2015. Diagnosis was confirmed by mycological examination. Skin scales were examined by direct microscopy and cultivated on Sabouraud glucose agar. A total of 226 patients were identified, representing 1.5% of all dermatophyte infections during the study period. Tinea corporis was diagnosed in majority of patients, followed by tinea manus, tinea faciei, tinea inguinalis and tinea pedis. Tinea capitis was observed in three and onychomycosis in two patients only. Infection was disseminated on different parts of the body in nine patients. In 39% of patients, infection was diagnosed in children younger than 9 years. Face and scalp infection was more often observed in children. The incidence was the highest during July and October. Contacts with soil and domestic animals were often reported. Data on the prevalence and clinical characteristics of M. gypseum complex infection in other countries are reviewed.

Abstract
Trichophyton (T.) rubrum is the most frequently isolated dermatophyte in onychomycosis, both in Germany and worldwide. T. interdigitale (formerly T. mentagrophytes var. interdigitale) follows in second place. A further however rarely isolated dermatophyte in onychomycosis is Epidermophyton floccosum. Candida parapsilosis, Candida guilliermondii, and Candida albicans, followed by Trichosporon spp. are the most important yeasts which are found in onychomycosis. The molds most often responsible include Scopulariopsis brevicaulis, and several Aspergillus species, e. g. Aspergillus versicolor, and Fusarium spp. These so called non-dermatophyte molds (NDM) are increasingly isolated as emerging pathogens in onychomycosis. The diagnosis of onychomycosis should be verified in the mycology laboratory. Conventional diagnostic methods include the direct examination, ideally using fluorescence staining with Calcofluor® or Blancophor®, and culture. However, new molecular biological methods primarily employing the polymerase chain reaction (PCR) for direct detection of dermatophyte DNA in skin scrapings and nail samples have been introduced into routine mycological diagnostics. The diagnostic sensitivity is higher when both conventional and molecular procedures are combined.

Abstract
From the epidemiological point of view, Trichophyton rubrum is the most important dermatophyte in the Western world. Mostly, the lesions of fungal infections of the skin are restricted and circumscribed. Immunodeficiency, diabetes or treatment with steroids, however, favour widespread disease involving the entire integument. In the present study, we describe a patient without immunodeficiency or diabetes presenting with widespread tinea corporis caused by T. rubrum. The fungal isolate showed atypical morphological features. Moreover, the typical metabolic features (negative urease test, production of red pigment on potato dextrose agar) were expressed with delay after 6 weeks of cultivation. Thus, sequencing of the internal transcribed spacer of the ribosomal DNA was applied to identify the fungal isolate and led us to the correct diagnosis, before conventional mycological methods were successful.

Abstract
The localisation of a dermatophytosis on the face is rare. Differential diagnoses include a broad range of dermatological disorders, e. g. contact dermatitis, psoriasis vulgaris, seborrhoeic dermatitis, demodicosis, and polymorphic photo eruptions. Two patients suffering from tinea faciei incognito caused by Trichophyton rubrum are presented. Diagnosis was based on mycological diagnostics of skin scrapings using Calcofluor preparation and cultivation of the causative dermatophyte. Both patients were suffering from tinea pedis and tinea unguium caused by the same dermatophyte species. An infection caused by Trichophyton rubrum of the face always occurs following autoinoculation from a pre-existing tinea pedis and tinea unguium of feet and toenails, sometimes of the fingernails.

Abstract
The clinical presentation of fungal infections of the skin, hair, or nails may be varied and confusing. To avoid delays in treatment and early spread of the infection, adequate diagnostics are necessary. This requires both the clinical expertise of the physicians as well as the capability to perform various laboratory tests. Classical methods are based on microscopy, different culture procedures, and histological examination. Genotypic approaches for the detection and identification of fungal pathogens have improved the speed and accuracy of laboratory diagnosis in the last few years, although further evaluation using molecular biology-based methods should be routinely applied in practice.

Abstract
We studied dermatophyte infections in patients, examined in the Mycological Laboratory of the Department of Dermatology, University Medical Centre Ljubljana during the period 1995-2002. A total of 42,494 samples were collected from 33,974 patients suspected to have dermatomycosis. Dermatophytes were identified in 8286 (71.2%) positive cultures. Microsporum canis was the most frequent dermatophyte isolated (46.8%), followed by Trichophyton rubrum (36.7%), T. mentagrophytes var. interdigitale (7.9%) and T. mentagrophytes var. mentagrophytes (4.9%). Less frequently isolated were M. gypseum, T. verrucosum, Epidermophyton floccosum, T. tonsurans and T. violaceum. The most common dermatophyte infections included tinea corporis, onychomycosis, tinea pedis and tinea faciei. Zoophilic dermatophytes were most commonly recovered from children and adolescents with tinea capitis, tinea corporis and tinea faciei. Anthropophilic species were identified mostly in adults with tinea pedis, onychomycosis and tinea inguinalis. During the period studied, we recorded a decline in the rate of M. canis infections, while infections produced by T. rubrum increased in frequency.

Abstract
Tinea capitis, which is caused by Trichophyton rubrum, is only rarely described in medical literature. Incidence of this disease appears to lie well below 1% in Europe. Microsporum canis, Trichophyton mentagrophytes and Trichophyton tonsurans are the predominant causative agents discussed here. In April 1993 T. rubrum was isolated from typical pathological changes to the capillitium area in three children from a Nigerian family, who had been living in Germany for 3 years. All three children revealed multiple, round or irregularly formed, partially infiltrated, partially pustular, hairless areas measuring up to 2 cm in diameter and covered with tightly clinging scales. The children's parents did not suffer from any dermatological complaints. The oldest child had had these pathological changes for about 5 months, the other two for a shorter length of time. Therapy with 10 mg kg(-1) body weight of griseofulvin led to rapid recovery over a period of 4 weeks.

Abstract
Trichophyton rubrum has led to unprecedented worldwide suppression of other dermatophytes which had been predominant earlier as a causative agent of superficial dermatomycoses. In tinea capitis on the other hand, several other species of Trichophyton or Microsporum are dominant depending on the region or continent. Tinea capitis caused by T. rubrum is a rare event worldwide. Occasional concentrations may be explained by several cases occurring by chance in one family or community. The relative frequency of this causative agent in tinea capitis in children is under 1%. In adults, however, where tinea capitis occurs very infrequently indeed, the incidence of T. rubrum appears to exceed 10%. Apart from two studies from India, one from Iran, two from Portugal and observations from Germany, which in the first country report of around 30% of all cases published, while the others document some 10% each, there are not only any conspicuous, unequivocal concentrations at all. Increased frequency of T. rubrum in this clinical picture has not been easily recognizable over the last decades due to low absolute case numbers.
