Tinea faciei clinical characteristics, causative agents, treatments and outcomes; a retrospective study in Thailand. Mycoses 2024; 67:e13754. [PMID: 38880935 DOI: 10.1111/myc.13754] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2024] [Revised: 06/04/2024] [Accepted: 06/08/2024] [Indexed: 06/18/2024]
Abstract
BACKGROUND Tinea faciei is a relatively uncommon dermatophyte infection. The studies, which included clinical forms, and isolated species of dermatophytes, are limited. MATERIALS AND METHODS This retrospective study aims to determine the causative organism, clinical characteristics, treatments and outcomes of patients with tinea faciei attending the dermatologic clinic, Siriraj Hospital, from 1 January 2017 to 30 September 2021. Demographic data, clinical presentations, isolated dermatophyte species, treatments and outcomes were collected and analysed. RESULTS A total of 151 tinea faciei cases were observed. Trichophyton rubrum (48.6%), Trichophyton mentagrophytes complex (22.2%) and Microsporum canis (18.1%) were common causative agents. Tinea faciei was commonly detected in females (64.9%) with a history of pets (54.6%). Clinical presentations often involved plaques and scales on the cheeks. Among patients with lesions on the cheek, mycological cure was observed significantly less often compared to those without cheek lesions. Patients with other concurrent skin or nail infections, a history of topical steroids and a history of previous fungal infection had a slightly longer duration of mycological cure than those without factors. Recurrent infection was found in 33.3%. Male, history of previous fungal infection, and lesions on the cheeks were significantly associated with recurrent infection. CONCLUSIONS Fungal infection of the face was commonly found in women and patients with pets. The most common pathogen that caused tinea faciei was T. rubrum. Topical antifungal treatments could be used with favourable outcomes. The history of past infection and lesion on the cheeks should be carefully assessed to be vigilant for recurrent infection.

Abstract
BACKGROUND Tinea faciei, a specific dermatophytosis that affects the glabrous skin of the face, not only causes physical discomfort but also leads to greater psychological distress. Tinea faciei is a public health concern. OBJECTIVES To analyse the epidemiological characteristics, responsible dermatophyte species and clinical features of tinea faciei in Hangzhou. METHODS Data were obtained from the Laboratory Information System of the Mycology Laboratory and Medical Information System at a hospital in Hangzhou. Isolates were identified based on their macroscopic appearance and microscopic morphology. RESULTS Tinea faciei was diagnosed in 701 patients, involving 359 males and 342 females, aged between 2 months and 97 years. In total, 499 isolates (71.18%) were identified as Trichophyton rubrum. Anthropophilic isolates were identified in 297 (82.73%) males and 207 (60.53%) females (p < .01). Among patients with anthropophilic dermatophytes infection, 447 (88.69%) were adults. Zoophilic dermatophytes were isolated in 57 (15.88%) males and 130 (38.01%) females (p < .01), among whom 108 (57.75%) were children. CONCLUSIONS Anthropophilic dermatophytes, especially T. rubrum, were the predominant cause of tinea faciei, while zoophilic dermatophytes were the most prevalent in children. Compared with men, women may be more susceptible to zoophilic dermatophytes.

Abstract
Dermatophytoses are fungal infections of the skin, hair, and nails that affect approximately 25% of the global population. Occlusive clothing, living in a hot humid environment, poor hygiene, proximity to animals, and crowded living conditions are important risk factors. Dermatophyte infections are named for the anatomic area they infect, and include tinea corporis, cruris, capitis, barbae, faciei, pedis, and manuum. Tinea incognito describes steroid-modified tinea. In some patients, especially those who are immunosuppressed or who have a history of corticosteroid use, dermatophyte infections may spread to involve extensive skin areas, and, in rare cases, may extend to the dermis and hair follicle. Over the past decade, dermatophytoses cases not responding to standard of care therapy have been increasingly reported. These cases are especially prevalent in the Indian subcontinent, and Trichophyton indotineae has been identified as the causative species, generating concern regarding resistance to available antifungal therapies. Antifungal-resistant dermatophyte infections have been recently recognized in the United States. Antifungal resistance is now a global health concern. When feasible, mycological confirmation before starting treatment is considered best practice. To curb antifungal-resistant infections, it is necessary for physicians to maintain a high index of suspicion for resistant dermatophyte infections coupled with antifungal stewardship efforts. Furthermore, by forging partnerships with federal agencies, state and local public health agencies, professional societies, and academic institutions, dermatologists can lead efforts to prevent the spread of antifungal-resistant dermatophytes.

Abstract
Simplicillium species are widely distributed with a broad spectrum of hosts and substrates. Generally, these species are entomopathogenic or mycoparasitic. Notably, some isolates of Simplicillium lanosoniveum and Simplicillium obclavatum were obtained from human tissues. In this study, two fungi were isolated from the annular itchy patch of infected skin of a 46-year-old man with diabetes mellitus. Based on a combination of morphological characteristics and phylogenetic analysis, a novel species, Simplicillium sinense, was introduced herein. It morphologically differs from the remaining Simplicillium in the size of phialides and conidia. Additionally, it grows slowly on YPD at 37°C. Antimicrobial susceptibility testing presented that this fungus is resistant to most azole antifungals. Therefore, the diagnosis of tinea faciei was made, and after 2 weeks of being treated with oral terbinafine (250 mg, once a day) and topical terbinafine cream for 1 month, the rash was mainly resolved and no recurrence happened after 6 months of follow-up. Herein, Simplicillium sinense was introduced as a new fungal taxon. Meanwhile, a case of superficial infection caused by S. sinense was reported. So far, it is the third Simplicillium species obtained from human tissue. Meanwhile, terbinafine is recommended as the first-line antifungal treatment against Simplicillium infection.

Abstract
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.

Abstract
We present a 76-year-old Japanese male with tinea faciei, tinea corporis, and tinea unguium with dermatophytoma. We performed fungal culture and confirmed the causative fungus to be Trichophyton rubrum. We treated the patient using oral fosravuconazole l-lysine ethanolate (F-RVCZ). More than one year has passed since the end of treatment, but there has been no recurrence. This case suggests that F-RVCZ is effective for tinea other than tinea unguium.

Abstract
Nannizzia gypsea is a geophilic dermatophyte, previously known as Microsporum gypseum before renaming under the new taxonomy. This organism is distributed all over the world and is considered to be involved in keratin degradation in the soil. Generally, human infection involves direct contact with fertile soil. Tinea caused by geophilic dermatophytes is much rarer than that caused by anthropophilic dermatophytes. According to the latest survey in Japan, dermatophytosis due to N. gypsea accounted for only 0.4% of cases. Clinical presentations vary and may mimic other inflammatory dermatitis, leading to incorrect diagnosis and delayed treatment. According to that past report, distal parts of the upper and lower extremities were more commonly affected, followed by the trunk, face and scalp, and rarely the nail plate. A 38-year-old woman presented with an approximately 3-week history of an itchy, solitary erythematous lesion on the left medial angle of the eyelid. Direct microscopic examination of scales revealed fungal elements, and the causative agents was identified as N. gypsea by morphological and molecular biological diagnoses. The eruption improved with systemic itraconazole treatment at 100 mg/day for 8 weeks. No recurrence has been seen for a year. However, she had no history of contact with any infectious source. Herein, we report a case of tinea faciei due to N. gypsea with an uncommon site and route of infection.

Abstract
Tinea faciei is a relatively uncommon dermatophytosis that affects the glabrous skin of the face. The aim of this study was to analyse the epidemiologic, clinical and mycological features of tinea faciei cases diagnosed at the Dermatology and Venereology Department of Hospital Santo António dos Capuchos (Lisbon, Portugal). Consecutive cases diagnosed between 2008 and 2016 were studied retrospectively. A total of 72 tinea faciei cases have been diagnosed, involving 37 male and 35 female, aged between 8 months and 86 years. The majority were observed in patients younger than 12 years of age (59.72%). Anthropophilic isolates (mainly Microsporum audouinii, Trichophyton soudanense and Trichophyton rubrum) accounted for 75.7% of the identified dermatophytes. One quarter of the patients were also affected by dermatophytosis in other areas, such as the scalp. Only 10 cases were previously treated with topical steroids due to misdiagnosis. Most patients were treated with topical and systemic antifungal therapy with total resolution of skin lesions, without relapse or side effects. In contrast to other European studies, anthropophilic dermatophytes were the main causative agents of tinea faciei. As previously described to tinea capitis, this result is probably due to changes in the epidemiology of dermatophytes worldwide.

Abstract
AbstractTinea incognito defines a modified clinical aspect of a tinea following an immunosuppressive therapy, mostly with potent topical steroids. Its diagnosis may be delayed by its delusive appearance, especially in small children and young adults. We present a series of 2 cases of Tinea incognito developed at different ages and incorrectly diagnosed initially, where the clinical diagnosis was followed by mycological examination and positive therapeutic test with antifungal medication, helping to avoid unnecessary laboratory investigations and to prevent further complications.

Abstract
Dermatophytoses are among the most frequently diagnosed skin infections worldwide. However, the distribution of pathogenic species and the predominating anatomical sites of infection vary with geographical location and change over time. The aim of this study was to determine the epidemiological and aetiological factors of dermatophytoses in Crete, Greece over the last 5-year period (2011-2015) and their incidence in relation to the gender and the age of the patients. We compared our findings with those previously reported from the same area and from other parts of the world. A total of 2,910 clinical specimens (skin scrapings, nail clippings, and hair specimens) obtained from 2,751 patients with signs of dermatomycoses were examined using direct microscopy and culture. Overall, 294 specimens (10.1%) were proved mycologically positive for dermatophytes. The age of the patients ranged from 2 to 86 years (mean age, 37 years). Tinea corporis was the predominant clinical type of infection, followed by tinea unguium, tinea pedis, tinea capitis, tinea faciei, tinea cruris and tinea manuum. Among dermatophytes, eight species were isolated: Microsporum canis (35.8%), Trichophyton rubrum (35.1%), Trichophyton mentagrophytes (23.3%), Epidermophyton floccosum (2.5%), Microsporum gypseum (1.8%), Trichophyton violaceum (0.7%), Trichophyton verrucosum (0.4%), and Trichophyton tonsurans (0.4%). In our area, the most common dermatophyte was M. canis followed by T. rubrum. Increased migration, mass tourism, and climate changes will contribute to further changes in the epidemiology of dermatophytoses in our area. Continuing studies are necessary for determining the new epidemiological trends and to implement the appropriate control measures.

Abstract
Background and Purpose: The epidemiological features of dermatophytoses have been characterized in many geographical locations of Iran, but not in Guilan, North of Iran. This study was carried out to determine the distribution pattern of dermatophytoses and their relevant agents in Guilan, North of Iran, over a period of one year, from April 2010 to April 2011. Materials and Methods: The clinical samples of skin, hair, and nail from 889 outpatients (317 men vs. 572 women) were used for direct microscopy and culture. All the culture-positive samples were then subjected to amplification of the internal transcribed spacer (ITS) of the nuclear rDNA followed by a restriction fragment length polymorphism (RFLP) assay to verify the causative agents. Results: The infection was confirmed in 90 (44.3%) males and 113 (55.7%) females. The most common type of dermatophytoses was tinea cruris (42.9%), followed by tinea pedis (20.2%), tinea corporis (11.3%), tinea unguium (7.4%), tinea faciei (6.9%), tinea manuum (6.4%), and tinea capitis (4.9%). ITS-RFLP based of the identification of isolates, showed that the infections were significantly associated with anthropophilic species, of Trichophyton rubrum (41.9%), Epidermophyton floccosum (19.7%), T. tonsurans (5.4%), and T.violaceum (2%). Other causative agents were T. interdigitale (22.6%), Microsporum canis (4.9%), T. verrucosum (2.5%), and M. gypseum (1%). Conclusion: The higher prevalence of T. rubrum, as the agent of dermatophytoses, than other species has never been reported from Iran and is of public health concern because of the chronic nature of infections with anthropophilic species. To thoroughly investigate the epidemiological trend of dermatophytoses in Iran, further periodical and molecular-based studies are necessary.

Abstract
Tinea faciei is a relatively uncommon dermatophyte infection entailing atypical
clinical symptoms, usually misdiagnosed and treated with corticosteroids. The
authors describe a case of tinea faciei on the right eyebrow caused by
Trichophyton interdigitale. The patient was an 18-year-old
girl, who had an inflammatory plaque with a scaly, pustular surface on the right
eyebrow and upper eyelid, which had persisted for over 1 month. She was once
misdiagnosed as having eczema and was treated using corticosteroid cream. A
diagnosis of tinea faciei was made based on direct microscopy and culture. The
sequencing of the nuclear ribosomal ITS region and β-tubulin gene of the
isolate established its T. interdigitale lineage. The patient
was cured by treatment with systemic terbinafine in combination with topical
application of 1% naftifine-0.25% ketaconazole cream for 2 weeks.

Abstract
Although candidiasis in newborns is not uncommon, superficial dermatophyte infections of infants is quite rare. The causative agents of neonatal tinea reported in various case studies have been Trichophyton rubrum, Microsporum canis, Microsporum gypseum, and Trichophyton violaceum. To the best of our knowledge, no case report of neonatal tinea faciei caused by Trichophyton mentagrophytes has been reported earlier.

Abstract
BACKGROUND Tinea capitis and tinea faciei are dermatophyte infections of the scalp and glabrous skin of the face affecting mainly prepubertal children. During the past 30 years, a significant increase and a change in the pattern of infectious agents has been noted for tinea capitis. OBJECTIVES The aim of this study was to determine trends in the current epidemiological situation of tinea capitis and tinea faciei in the Zurich area, Switzerland and adjacent Central and Eastern Switzerland. METHODS Consecutive cases diagnosed between 2006 and 2013 were studied retrospectively. RESULTS A total of 90 tinea capitis and 40 tinea faciei cases were observed. Anthropophilic isolates (primarily Trichophyton violaceum and Microsporum audouinii) accounted for 76% of tinea capitis cases. In contrast, zoophilic isolates (primarily T. interdigitale) were responsible for 73% of tinea faciei cases. The peak incidence in both conditions was in 4-8 year-old children. While the annual number of tinea faciei cases remained stable over the past 8 years, a trend for an increase in T. violaceum-positive tinea capitis has been observed. This was mainly due to patients of African ethnicity. CONCLUSIONS Anthropophilic isolates accounted for three quarters of tinea capitis and one quarter of tinea faciei cases. T. violaceum-positive tinea capitis was primarily linked to patients of African ethnicity. Tinea capitis caused by Microsporum spp. was more refractory to therapy and needed longer treatment than Trichophyton spp.-induced infection.

Abstract
BACKGROUND Dermatophytes can be divided into geophilic (soil), zoophilic (animals) and anthropophilic (human) strains, depending on the source of the keratin. The predominant organisms vary within a given geographical region during different periods, which is influenced by a number of factors, such as population movements, socioeconomic circumstances and level of surveillance. Thus, the incidence is very variable. AIM To determine the epidemiology of superficial fungal infections due to zoophilic and geophilic fungi in patients referred to the Pasteur Institute of Iran. METHODS The clinical presentation of zoophilic and geophilic dermatophyte-related infections was reviewed retrospectively from the medical records of all subjects referred to our laboratory for assessment of cutaneous fungal infection. Mycological examination consisted of culturing of pathological material followed by direct microscopy. Diagnosis was based on the macroscopic and microscopic characteristics of the colonies. RESULTS Of the 3976 clinically suspected cases of dermatophytosis, 239 (39.6%) were zoophilic dermatophytosis, confirmed by direct examination and culture. They occurred in 93 (39%) female patients and 146 (61%) male patients (median age 27.4 years, range 1.5-75). The commonest zoophilic fungi isolated were Trichophyton mentagrophytes var. mentagrophytes (28%), followed by Trichophyton verrucosum (9.3%) and Microsporum canis (2.2%). The geophilic fungus Microsporum gypseum was isolated from 0.33% of patients. CONCLUSION This study identifies the epidemiological trends and the predominant organisms causing zoophilic dermatophytosis in humans in Tehran. Consideration of the current epidemiological trends in the incidence of cutaneous zoophilic fungal pathogens is essential for investigation, diagnosis and treatment.

Abstract
Dermatophytoses are frequent in children, but involvement of the facial skin has peculiar aspects that should be considered a separate entity: tinea faciei. Microsporum canis infection in tinea faciei has not been widely documented. To review cases of tinea faciei due to M. canis in children diagnosed at the Dermatology Clinic, University of Cagliari. Between 1990 and 2009, all children with dermatophyte infections of the facial skin were recruited for the study after parental consent. Diagnosis was made through direct microscopic and cultural examination. Age, sex, clinical form, illness duration, identified dermatophyte, source of infection, and treatment were recorded. Forty-six cases of tinea faciei due to M. canis in children aged 11 months to 15 years (29 male/17 female) were diagnosed. In 42 (91.3%) children, the illness was the result of contact with pets, and 4 (8.7%) cases resulted from contact with children affected by tinea capitis due to M. canis. Clinical manifestations were typical ringworm in 34 (74%) patients, whereas in 12 (26%) cases, atypical forms mimicking atopic dermatitis, impetigo, lupus erythematosus, and periorificial dermatitis were observed. In 18 (39%) cases, involvement of the vellus hair follicle was documented as ectothrix invasion. Topical or systemic antifungal therapy was effective in all patients. Tinea faciei shows a complex spectrum of differential diagnosis and age-related variations with respect to other superficial dermatophytosis. M. canis is the main organism responsible in children residing in Cagliari, capitol city of Sardinia, Italy. Close collaboration with veterinary and educational programs within infant communities are required for adequate prevention.

Abstract
Tinea faciei (TF) is a common clinical form of tinea in children that is frequently misdiagnosed and treated with corticosteroids. No large case series of TF focusing on children have been published. The aim of this study was to analyze the main epidemiologic, clinical, and microbiologic features of TF in children over a period of 30 years and compare these features with those of other tineas. We undertook a retrospective study of 818 cases of tinea in children at a referral hospital in southern Spain, diagnosed between 1977 and 2006, concentrating for this study on TF. Of the 73 cases of TF diagnosed, 50.7% were in girls. Most children (46.6%) were 4 to 9 years old. At the time of diagnosis, 29.2% of the cases had been treated with topical steroids. The most frequently isolated dermatophyte was Trichophyton mentagrophytes, which was isolated significantly more frequently in TF than in the other tineas. Cases of TF in children were not extremely unusual, emphasizing that TF must be considered in children with inflammatory facial eruptions. This consideration and the more-frequent use of mycologic tests can help achieve the correct diagnosis, when present.

Abstract
Tinea faciei is an uncommon dermatophytosis affecting the glabrous skin of the face. Between 1988 and 2007 at the Dermatology Department of Cagliari University, 107 cases of tinea faciei have been diagnosed, involving 72 females and 35 males, aged 2-72 years. Incidence peaks were observed between 6 and 15 years (48.59%) and between 36 and 45 years (17.76%). Males below and females above 15 years of age were the most affected. In 61 patients (57.1%), typical forms of tinea faciei were observed, whereas in 46 (42.9%), atypical forms were observed, mainly mimicking discoid lupus erythematosus (nine cases), and polymorphous light eruption (eight cases). Typical cases were present in younger patients, aged between 2 and 15 years, while atypical forms were distributed in any of the decades, but mostly between 36 and 72 years. Of the 46 cases of atypical presentation, 33 were females. The isolated dermatophytes were Microsporum canis (63 cases), Trichophyton rubrum (24 cases) and T. mentagrophytes var. mentagrophytes (20 cases). Seven males and two females aged 4-10 years were also affected by tinea capitis and eight patients (three males and five females) of various ages by tinea corporis. Eleven patients (two males and nine females) aged >35 years were affected by onychomycosis. All patients recovered after local and/or systemic antifungal therapy, without relapse or side effects.

Abstract
Consecutive cases of tinea faciei diagnosed in Siena between 1989 and 2003 were studied retrospectively for differences in clinical form, demographic data and species of dermatophyte isolated. The series consisted of 84 cases (59 females, 25 males) with a mean age of 27 years. Mean age of females (32.4 years) was significantly greater than that of males (14.2 years). The dermatophytes most frequently isolated were Microsporum canis (38 cases) and Trichophyton rubrum (31 cases). Clinical form was typical of tinea in 54 subjects (64.3%) and was tinea incognito because of inappropriate therapy in the other 30 (35.7%) subjects. The mean age of patients with the typical form (19.2 years) was significantly lower than that of those with tinea incognito (41.1 years). All cases in the age range 6-15 years had typical tinea, whereas the maximum frequency of cases with tinea incognito was 46-50 years. In the group with tinea incognito there was a majority of women and the dermatophytes isolated differed with gender. No such difference was observed in the group with typical tinea.
