Abstract
Tinea incognito is a dermatophyte infection with atypical features, due to the use of topical or systemic steroids or other immunosuppressive medications. Delayed diagnosis, spread of the infection to critical body surfaces, resistance to antifungal drugs, and increased costs due to prolonged hospitalization and multiple treatment regimens often complicate tinea incognito. It can affect individuals of all ages and genders, but it is more common in children. Atypical clinical appearance often necessitates differentiation from other diseases such as eczema, seborrheic dermatitis, lupus erythematosus, psoriasis, or other non-fungal skin conditions. The treatment of tinea incognito usually involves discontinuation of topical steroids or other immunosuppressive medications. Preventive measures and management of the underlying fungal infection are necessary and can be achieved with antifungal drugs. Patients should wear loose cotton clothes, use boiling water for laundry, and iron their clothing before wearing them. Additionally, they should avoid sharing bed linens, towels, clothes, and shoes. This review aims to raise awareness of tinea incognito among health practitioners, provide tips for detecting the disorder, include it in the differentials, and evaluate the available diagnostic procedures.

Abstract
While typically exhibiting characteristic features, fungal infections can sometimes present in an unusual context, having improbable localization (eyelid, face, or joint); mimicking other skin diseases such as eczema, psoriasis, or mycosis fungoides; and appearing with unexpected color, shape, or distribution. The emergence of such a challenging clinical picture is attributed to the complex interplay of host characteristics (hygiene and aging population), environment (climate change), advances in medical procedures, and agent factors (fungal resistance and species emergence). We aim to provide a better understanding of unusual epidemiological contexts and atypical manifestations of fungal superficial diseases, knowing that there is no pre-established clinical guide for these conditions. Thus, a literature examination was performed to provide a comprehensive analysis on rare and atypical superficial mycosis as well as an update on certain fungal clinical manifestations and their significance. The research and standard data extraction were performed using PubMed, Medline, Scopus, and EMBASE databases, and a total of 222 articles were identified. This review covers published research findings for the past six months.

Abstract
Dermatophytosis has attained unprecedented dimensions in recent years in India. Its clinical presentation is now multifarious, often with atypical morphology, severe forms and unusually extensive disease in all age groups. We hesitate to call it an epidemic owing to the lack of population-based prevalence surveys. In this part of the review, we discuss the epidemiology and clinical features of this contemporary problem. While the epidemiology is marked by a stark increase in the number of chronic, relapsing and recurrent cases, the clinical distribution is marked by a disproportionate rise in the number of cases with tinea corporis and cruris, cases presenting with the involvement of extensive areas, and tinea faciei.

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
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
Significant changes in epidemiology, etiology, and the clinical pattern of mycotic infections caused by Microsporum spp have been observed in recent years. Fungal infections caused by M canis, followed by M gypseum and M hominis, involving skin and its appendages, represent one of the most common diseases worldwide and a recalcitrant problem in dermatology that demands appropriate diagnostic and treatment strategies. The most striking clinical phenomena of superficial and kerion and other forms of tinea, such as tinea capitis, fungal infections of the glabrous skin (tinea pedis, manus, cruris et corporis), and even onychomycosis due to Microsporum spp are described, with emphasis on the changes that have occurred in the last decade. The data on significant differences in the prevalence and clinical pattern of the fungal skin infections caused by Microsporum spp today compared with the data at the beginning of the epidemic breakout might still be rather controversial, depending also on the patients' lifestyle and geography. In general, physicians should be aware of the clinical spectrum of mycotic infections due to Microsporum spp to avoid mistakes in identifying the fungal etiology and to provide patients with the proper therapy.

Abstract
Tinea incognito was first described 50 years ago. It is a dermatophytic infection with a clinical presentation modified by previous treatment with topical or systemic corticosteroids, as well as by the topical application of immunomodulators such as pimecrolimus and tacrolimus. Tinea incognito usually resembles neurodermatitis, atopic dermatitis, rosacea, seborrheic dermatitis, lupus erythematosus, or contact dermatitis, and the diagnosis is frequently missed or delayed.

Abstract
Tinea incognito or steroid modified tinea is a dermatophytic infection in which topical or systemic steroids, administered as a result of dermatological misdiagnosis or preexisting pathologies, have modified the clinical appearance of the fungal infection, transforming the typical ringworm and mimicking other skin diseases. This is a retrospective study of the agents, clinical aspects, sources of infection of 200 cases (98 males, 102 females, mean age 42 years) of tinea incognito, observed in Siena and Milan, Italy, in the period 1987-2002. In order of decreasing frequency, Trichophyton rubrum, Trichophyton mentagrophytes, Epidermophyton floccosum, Microsporum canis, Microsporum gypseum, Trichophyton violaceum and Trichophyton erinacei were isolated. The clinical appearance of the infection was lupus erythematosus discoid-like, eczema-like, rosacea-like, especially on the face, impetigo-like and eczema-like on trunk and limbs. Less often the dermatophytosis resembled psoriasis, purpura, seborrhoic dermatitis and lichen planus. There was folliculitis in 9% of cases and dermatophytid in 3% of cases. Antimycotic therapy brought about clinical and mycological recovery in all patients except one, who had iatrogenic immunodepression.

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.

Abstract
Dermatophytoses, commonly known as ringworm or tinea, represent superficial fungal infections caused by dermatophytes, which are among the most common infections encountered in medicine. The use of corticosteroid-containing combinations in dermatophyte infections that are usually treated with topical medications is still a much-debated issue. The addition of a corticosteroid to local antifungal therapy may be of value in reducing local inflammatory reaction and thus carries the theoretical advantage of rapid symptom relief in acute dermatophyte infections associated with heavy inflammation. However, the use of such combinations requires caution as they have some potential risks, especially with long-term use under occlusive conditions. Corticosteroid-induced cutaneous adverse effects have been reported primarily in pediatric patients due to inappropriate application of these preparations on diaper areas. Additionally, the corticosteroid component may interfere with the therapeutic actions of the antifungal agent, or fungal growth may accelerate because of decreased local immunologic host reaction, such that underlying infection may persist, and dermatophytes may even acquire the ability to invade deeper tissues. Analysis of the literature documenting clinical study data and adverse reactions related to combination therapy, drew the following conclusions: (i) combination products containing a low potency nonfluorinated corticosteroid may initially be used for symptomatic inflamed lesions of tinea pedis, tinea corporis, and tinea cruris, in otherwise healthy adults with good compliance; (ii) therapy should be substituted by a pure antifungal agent once symptoms are relieved, and should never exceed 2 weeks for tinea cruris and 4 weeks for tinea pedis/corporis; and (iii) contraindications for the use of these combinations include application on diaper or other occluded areas and facial lesions, as well as in children <12 years of age and in immunosuppressed patients for any reason.

Abstract
We report a 10-year-old Caucasian child who had erythema and abundant scaling on the nasolabial folds, the upper lip, and on the nose. Both the abundant scaling and the localization on the central part of the face led us to suspect seborrheic dermatitis. Direct microscopic examination of some scales removed from the lesions showed septate and ramified ectothrix hyphae. Cultural examination on Sabouraud medium led to the identification of the Trichophyton mentagrophytes species. We described this patient to highlight the importance of considering tinea faciei in the differential diagnosis of all facial eruptions and the value of mycologic examination.

Abstract
Tinea incognito has first been described in 1968. The term describes a tinea infection whose clinical morphology has been modified by the application of topical corticosteroids. The clinical manifestation can masquerade a number of other dermatoses and leads to misdiagnosis of annular eruptions. We describe a patient who showed a bizarre appearance of annular, inflammatory skin lesions at the umbilical region. Mycological culture yielded Microsporum canis.

We report the case of a 36-year-old man who presented large erythematous plaques involving the trunk, face and extremities, since one month. Some of these lesions had a psoriasis-like aspect, with abundant superficial scaling. Direct microscopic examination of scales removed from the plaques revealed numerous hyphae. Cultural examination lead to the identification of Trichophyton rubrum species. Our case of tinea corporis presented some peculiarities related both to the extension of the lesions and their clinical aspects.
