Zoonotic Majocchi's Granuloma of the Vulva.

A healthy 32-year-old woman presented to clinic with tender pruritic lesions of 2-month duration at the vulva and lesions for weeks on the shins. She was treated with topical corticosteroids and intravenous vancomycin without significant improvement. On examination, dozens of follicular hemorrhagic papulopustules were detected at the suprapubic area and vulva (Figure 1). Similar but less prominent lesions were observed on the shins as well. Biopsies of the vulva and shin revealed a follicular inflammatory infiltrate of neutrophils, histiocytes, and lymphocytes as well as fungal hyphae within the follicular infundibulum and hair shafts, consistent with Majocchi's granuloma (MG). Gram and Fite-Faraco staining, direct immunofluorescence, and bacterial culture were negative. Tissue culture grew Trichophyton mentagrophytes, which was identified using sequence analysis of the D1/D2 region of the 28s rDNA. Minimum inhibitory concentrations for terbinafine, ketoconazole, and itraconazole were determined, with terbinafine having the lowest concentration. Additional history revealed that shortly prior to commencement of her clinical manifestations, the patient had acquired a pet guinea pig with eruptions and hair loss (Figure 2). The patient was prescribed ketoconazole cream and terbinafine, 250 mg daily, with almost immediate improvement. Based on clinical response, the patient remained on terbinafine and ketoconazole cream for 6 months. Her skin remained clear 4 months after discontinuing all antifungals. Based on the results of patient's culture, a veterinarian treated her guinea pig successfully with systemic terbinafine and miconazole lotion.

A Case of Tinea Faciei due to Trichophyton indotineae with Steroid Rosacea Related to Topical Over-The-Counter Drugs Purchased Outside of Japan.

A Filipino woman in her forties had facial erythema that was being self-treated with over-the-counter (OTC) drugs purchased outside of Japan. The drugs included clobetasol propionate, antibiotic, and antifungal components. Her facial erythema symptoms were worse during summertime. KOH direct examination of annular erythema was positive for fungal hyphae and negative for Demodex folliculorum. Fungal culture revealed Trichophyton indotineae based on internal transcribed spacer sequence analysis. Minimal inhibitory concentration for terbinafine was 0.06 µg/mL. We made a diagnosis of tinea faciei with steroid rosacea. We treated the patient with oral itraconazole. Physicians should be aware of increasing T. indotineae infections and increasing self-medication using topical OTC steroids combined with antifungals and antibiotics not only in India but also among foreign people living in other countries such as Japan.

Deep dermatophytosis caused by Trichophyton rubrum in an elderly patient with CARD9 deficiency: A case report and literature review.

Deep dermatophytosis is an invasive and sometimes life-threatening fungal infection mainly reported in immunocompromised patients. However, a caspase recruitment domain-containing protein 9 (CARD9) deficiency has recently been reported to cause deep dermatophytosis. Herein, we report the first Japanese case of deep dermatophytosis associated with CARD9 deficiency. An 80-year-old Japanese man with tinea corporis presented with subcutaneous nodules on his left sole. Histopathological findings revealed marked epithelioid cell granulomas with filamentous fungal structures in the deep dermis and subcutis, and the patient was diagnosed with deep dermatophytosis. Despite antifungal therapy, the subcutaneous nodule on his left sole gradually enlarged, his left calcaneal bone was invaded, and the patient finally underwent amputation of his left leg. Genetic analysis revealed a homozygous CARD9 c.586 A > G (p. Lys196Glu) variant, suggesting a CARD9 deficiency. Here, we discuss the clinical features of CARD9 deficiency-associated deep dermatophytosis with a case report and review of the literature.

Deep-seated dermatophytosis caused by Trichophyton rubrum in patient with Becker muscular dystrophy.

Trichophyton rubrum is a common fungal pathogen that usually causes superficial infection limited to epidermis only, so called dermatophytosis. However in immunocompromised patients, dermatophytosis can be exceptionally more invasive with extensive lesions involving deep tissues and generating sometimes systemic course. We report the case of a 43-year-old heart transplanted man, who presented with multiple deep-seated nodules and papules in the inguinal areas and in the buttocks. Involvement of Trichophyton rubrum was confirmed by culture, DNA sequencing and histological examination that showed granulomatous inflammatory infiltrates with the presence of hyphae in the dermis. Antifungal therapy with oral terbinafine for four weeks was successful; in spite of initial remnant atrophic scars, the lesions were completely cleared after four month evolution. Deep-seated invasive dermatophytosis is rare, but should be considered with immunocompromised conditions, especially when history of previous superficial dermatophytosis is present.

Kerion Celsi in infants and children-A narrative review 2010-2023.

Kerion Celsi is an inflammatory, deep fungal infection of the scalp. It is rare in neonates but gets more common in children about 3 years and older. It represents with swelling, boggy lesions, pain, alopecia and purulent secretions. Secondary bacterial infection is not unusual after maceration. Extracutaneous manifestations include regional lymphadenopathy, fever and very rare fungemia. Id-reactions can occur. Diagnosis is based on clinical suspicion, clinical examination and medical history. Diagnosis should be confirmed by microscopy, fungal culture and molecular procedures. The most common isolated fungal species are anthropophilic Trichophyton (T.) tonsurans and zoophilic Microsporum (M.) canis, while geophilic species and moulds rarely cause Kerion Celsi. Treatment is medical with systemic and topical antifungals supplemented by systemic antibiotics when necessary, while surgery needs to be avoided. Early and sufficient treatment prevents scarring alopecia. The most important differential diagnosis is bacterial skin and soft tissue infections.

Erythroderma combined with deeper dermal dermatophytosis due to Trichophyton rubrum in a patient with myasthenia gravis: first case report and literature review.

BACKGROUND: Dermatophytes are the most common causative pathogens of mycoses worldwide and usually cause superficial infections. However, they can enter deep into the dermis lead to invasive dermatophytosis such as deeper dermal dermatophytosis on rare occasions. Erythroderma is a severe dermatological manifestation of various diseases resulting in generalized skin redness, but erythroderma due to fungi infections is barely reported. In this article, we reported the first case of erythroderma combined with deeper dermal dermatophytosis due to Trichophyton rubrum (T. rubrum) in a patient with myasthenia gravis. CASE PRESENTATION: A 48-year-old man was hospitalized because of erythema with scaling and nodules covering his body for a month. The patient had a history of myasthenia gravis controlled by regularly taking prednisolone for > 10 years and accompanied by onychomycosis and tinea pedis lasting > 8 years. Based on histopathological examinations, fungal cultures, and DNA sequencing results, the patient was finally diagnosed with dermatophyte-induced erythroderma combined with deeper dermal dermatophytosis caused by T. rubrum. After 2 weeks of antifungal treatment, the patient had recovered well. CONCLUSIONS: This case report shows that immunosuppressed patients with long histories of superficial mycoses tend to have a higher risk of developing invasive dermatophytic infections or disseminated fungal infections. Dermatologists should be alert to this condition and promptly treat the superficial dermatophytosis.

Cytomorphological findings of Trichophyton rubrum infection in an elderly hypertensive woman.

Trichophyton is a dermatophytic fungi causing superficial skin infections which affects outermost layer of the epidermis, stratum corneum, and mainly involves feet, groin, scalp, and nails. Invasion into the dermis occurs mainly in immunocompromised patients. A 75-year-old hypertensive female presented with a nodular swelling on the dorsum of right foot for 1 month. The swelling was 1.0 × 1.0 cm and gradually progressive in nature. FNAC revealed many thin filamentous branching and fungal hyphae along with foreign body granulomas and suppurative acute inflammation. The swelling was excised and sent for histopathological examination which confirmed the above findings. Periodic Acid Schiff stain showed fungal hyphae in both cytology smear as well as histopathology section. On fungal culture, microconidia with septate hyphae suggestive of Trichophyton rubrum was seen. Trichophytons mainly affect immunocompromised and diabetic patients, however, may present as nodular lesions without any history of superficial dermatophytosis as seen in the present case. The characteristic cytological picture helped to clinch the diagnosis in this case and facilitated further management.

Treatment recalcitrant cases of tinea corporis/cruris caused by T. mentagrophytes - interdigitale complex with mutations in ERG11 ERG 3, ERG4, MDR1 MFS genes & SQLE and their potential implications.

BACKGROUND: Recalcitrant dermatophyte infections are being reported from various parts of the world due to varied causes including strain variation, steroid misuse, SQLE mutations, and variable quality of itraconazole pellet formulations. The oral drug preferred in endemic areas is itraconazole, to which MIC levels remain low, and clinical failures to itraconazole reported defy a sound scientific explanation. OBJECTIVES: The objective of the study was to conduct a proteomic and genomic analysis on isolates from therapeutically recalcitrant case with isolation of gene mutations and enzymatic abnormalities to explain azole failures. METHODS: Trichophyton mentagrophyte interdigitale complex strains were isolated from seven clinically non-responding tinea corporis/cruris patients, who had failed a sequential course of 6 weeks of terbinafine 250 mg QD and itraconazole 100 mg BID. After AFST 1 strain, KA01 with high MIC to most drugs was characterized using whole genome sequencing, comparative proteomic profiling, and total sterol quantification. RESULTS: Sterol quantification showed that the standard strain of Trichophyton mentagrophytes (MTCC-7687) had half the ergosterol content than the resistant KA01 strain. Genomic analysis revealed mutations in SQLE, ERG4, ERG11, MDR1, MFS genes, and a novel ERG3 mutation. Proteomic analysis established the aberrant expression of acetyl Co-A transferase in the resistant strain and upregulation of thioredoxin reductase and peroxiredoxin. CONCLUSION: Our findings demonstrate possible reasons for multidrug resistance in the prevalent strain with mutations in genes that predict terbinafine (SQLE) and azole actions (ERG4, ERG11, ERG3) apart from efflux pumps (MDR1, MFS) that can explain multidrug clinical failures.

The role of pacas of captivity as a potential reservoir of zoonotic fungi in Acre, Western Amazon, Brazil / O papel de pacas de cativeiro como potencial reservatório de fungos zoonóticos no Acre, Amazônia Ocidental, Brasil

Wild animals can be natural reservoirs of different microorganisms, essential for monitoring these pathogens for the generation of knowledge and creation of tools aimed at programs for the prevention and control of infectious diseases, including zoonoses. The objective was to report the fungal diversity in the skin of pacas in captivity in Acre, Western Amazon, Brazil. Twenty-six animals were evaluated, from which skin samples were collected by superficial scraping, hair avulsion, and sterile plastic brush. The samples were seeded on Mycosel agar, and the phenotypic characteristics of the colonies were analyzed. In 80.8% of the samples, different fungi were isolated, from the genera Candida, Microsporum,and Trichophyton, among others. This is the first description of the identification of fungi in the skin of pacas and suggests that these animals can be considered essential reservoirs of saprophytic or pathogenic microorganisms with zoonotic potential in the Western Amazon.(AU)

Animais silvestres podem ser reservatórios naturais de diferentes microrganismos, sendo fundamental o monitoramento destes patógenos para a geração de conhecimento e criação de ferramentas direcionadas a programas de prevenção e controle de enfermidades infecciosas, incluindo as zoonoses. Assim, objetivou-se relatar a diversidade fúngica da pele de pacas criadas em cativeiro no Acre, Amazônia Ocidental, Brasil. Foram avaliados 26 animais, dos quais amostras cutâneas foram colhidas por raspagem superficial, avulsão pilosa e escova plástica estéril. As amostras foram semeadas em ágar Mycosel e as características fenotípicas das colônias foram analisadas. Em 80,8% das amostras houve isolamento de diferentes fungos, dos gêneros Candida, Microsporum e Trichophyton, dentre outros. Esta é a primeira descrição da identificação de fungos na pele de pacas e sugere que estes animais podem ser considerados importantes reservatórios de microrganismos saprófitas ou patogênicos, de potencial zoonótico, na Amazônia Ocidental.(AU)

New taxonomic framework for Arthrodermataceae: a comprehensive analysis based on their phylogenetic reconstruction, divergence time estimation, phylogenetic split network, and phylogeography.

The Arthrodermataceae, or dermatophytes, are a major family in the Onygenales and important from a public health safety perspective. Here, based on sequenced and downloaded from GenBank sequences, the evolutionary relationships of Arthrodermataceae were comprehensively studied via phylogenetic reconstruction, divergence time estimation, phylogenetic split network, and phylogeography analysis. These results showed the clades Ctenomyces, Epidermophyton, Guarromyces, Lophophyton, Microsporum, Paraphyton, and Trichophyton were all monophyletic groups, whereas Arthroderma and Nannizzia were polyphyletic. Among them, Arthroderma includes at least four different clades, Arthroderma I, III and IV are new clades in Arthrodermataceae. Nannizzia contains at least two different clades, Nannizzia I and Nannizzia II, but Nannizzia II was a new clade in Arthrodermataceae. The unclassified group, distributed in Japan and India, was incorrectly identified; it should be a new clade in Arthrodermataceae. The phylogenetic split network based on the ITS sequences provided strong support for the true relationships among the lineages in the reconstructed phylogenetic tree. A haplotype phylogenetic network based on the ITS sequences was used to visualize species evolution and geographic lineages relationships in all genera except Trichophyton. The new framework provided here for the phylogeny and taxonomy of Arthrodermataceae will facilitate the rapid identification of species in the family, which should useful for evaluating the results of preventive measures and interventions, as well as for conducting epidemiological studies.

Tiña capitis por Trichophyton tonsurans en un paciente pediátrico / Tinea capitis by Trichophyton tonsurans in a pediatric patient

La tiña capitis (TC) es una micosis superficial del cuero cabelludo, considerada una de las infecciones más frecuentes por dermatofitos en niños. Hasta la actualidad, las especies descritas con mayor frecuencia en nuestro medio son el Microsporum y, en segundo término, Trichophyton, los cuales se contraen principalmente por contacto directo con animales o seres humanos infectados, respectivamente. Se presenta el caso de una paciente de 8 años con alopecia y lesiones inflamatorias de 2 años de evolución, en la que finalmente se llegó al diagnóstico de TC inflamatoria causada por T. tonsurans, un hongo antropofílico considerado poco frecuente en Argentina y emergente en la provincia de Buenos Aires. Este patógeno presenta alta transmisibilidad; son varios los países que han reportado brotes escolares y comunitarios. Se debe resaltar la importancia de su sospecha clínica temprana para un tratamiento adecuado.

Tinea capitis (TC) is a superficial mycosis of the scalp, considered one of the most common dermatophyte infections in children. Until now, the species mainly described in our environment are Microsporum and secondly Trichophyton, which are contracted mainly by direct contact with infected animals or humans, respectively. We present the case of an 8-year-old patient with alopecia and inflammatory lesions of 2 years of evolution, finally reaching the diagnosis of inflammatory tinea capitis caused by T. tonsurans, an anthropophilic fungus considered rare in Argentina and emerging in the province of Buenos Aires. This pathogen has high transmissibility; several countries have reported school and community outbreaks. The importance of its early clinical suspicion for adequate treatment should be emphasized.

Isoflavaspidic Acid PB Extracted from Dryopteris fragrans (L.) Schott Inhibits Trichophyton rubrum Growth via Membrane Permeability Alternation and Ergosterol Biosynthesis Disruption.

Isoflavaspidic acid PB (PB), a phloroglucinol derivative extracted from aerial parts of Dryopteris fragrans (L.) Schott, had antifungal activity against several dermatophytes. This study was aimed at exploring the antifungal mechanism of PB against Trichophyton rubrum (T. rubrum). The effectiveness of PB in inhibiting T. rubrum growth was detected by time-kill kinetics study and fungal biomass determination. Studies on the mechanism of action were investigated using scanning electron microscopy (SEM), transmission electron microscopy (TEM), sorbitol and ergosterol assay, nucleotide leakage measurement, and UPLC-based test and enzyme-linked immunosorbent assay. Fungicidal activity of PB was concentration- and time-dependent at 2 × MIC (MIC: 20 µg/mL) after 36 h. The total biomass of T. rubrum was reduced by 64.17%, 77.65%, and 84.71% in the presence of PB at 0.5 × MIC, 1 × MIC, and 2 × MIC, respectively. SEM analysis showed that PB changed mycelial morphology, such as shrinking, twisting, collapsing, and even flattening. TEM images of treated cells exhibited abnormal distributions of polysaccharide particles, plasmolysis, and cytoplasmic content degradation accompanied by plasmalemma disruption. There were no changes in the MIC of PB in the presence of sorbitol. However, the MIC values of PB were increased by 4-fold with exogenous ergosterol. At 4 h and 8 h, PB increased nucleotide leakage. Besides, ergosterol content in T. rubrum membrane treated with PB at 0.5 × MIC, 1 × MIC, and 2 × MIC was decreased by 9.58%, 15.31%, and 76.24%, respectively. There was a dose-dependent decrease in the squalene epoxidase (SE) activity. And the reduction in the sterol 14α-demethylase P450 (CYP51) activity was achieved after PB treatments at 1 × MIC and 2 × MIC. These results suggest that PB displays nonspecific action on the cell wall. The membrane damaging effects of PB were attributed to binding with ergosterol to increase membrane permeability and interfering ergosterol biosynthesis involved with the reduction of SE and CYP51 activities. Further study is needed to develop PB as a natural antifungal candidate for clinical use.

Dermatofitosis por Microsporum gypseum en un niño con inmunodeficiencia primaria / Microsporum gypseum dermatophytosis in a child with primary immunodeficiency

El Microsporum gypseum es un hongo geofílico que puede producir lesiones cutáneas inflamatorias en personas sanas. Se han descripto lesiones más extensas en pacientes inmunocomprometidos. Se presenta el caso de un paciente con dermatofitosis, con exámenes micológicos positivos para Candida sp, Epidermophytom floccosum y Trichophyton tonsurans, al que, ante la mala respuesta al tratamiento con griseofulvina e itraconazol a dosis habituales, se le realizó biopsia cutánea para cultivo que evidenció la presencia de M. gypseum. Debido a la extensión y a la mala respuesta al tratamiento, se realizó evaluación inmunológica y se diagnosticó un defecto en STAT1 con ganancia de función (STAT1-GOF). Los pacientes que tienen esta inmunodeficiencia primaria son susceptibles a las infecciones micóticas, especialmente por Candida, pero también, aunque en menor medida, a virus y bacterias. El paciente aquí presentado recibió tratamiento prolongado con antimicóticos imidazólicos sistémicos, con resolución de las lesiones.

Microsporum gypseum is a geophilic fungus that can cause inflammatory skin lesions in heathy people. More extensive lesions have been described in immunocompromised patients. We present a patient with extensive dermatophytosis, which mycological examination led the identification of Candida sp, Epidermophyton Floccosum and Trichophyton tonsurans and showed poor response to treatment with griseofulvina and itraconazol at usual doses. When skin biopsy was performed, it had positive culture for M. gypseum. Due to the extension and poor response to treatment, immunological assessment was performed and it showed a defect of STAT1 with gain of function (STAT 1-GOF). Patients with primary immunodeficiency are susceptible to fungal infections, especially Candida but also virus and bacteria, although to a lesser extent. The patient received long-term treatment with systemic imidazole antifungal recovering for the lesions.

Bedside Diagnosis for Disseminated Deep Dermatophytosis: a Case Series Study.

Deep cutaneous fungal infections including deep dermatophytosis are responsible for significant morbidity and mortality, especially in immunocompromised patients. Variable and longer turnaround time on tissue culture results delay diagnosis. We sought to seek the fast bedside diagnosis for disseminated deep dermatophytosis by direct microscopy using a blunt scalpel or needle aspiration before biopsy. This is a 6-year retrospective review of patients with a diagnosis of disseminated deep dermatophytosis seen at a single tertiary care institution. Trichophyton rubrum was isolated in four patients, and T. mentagrophyte complex in one patient. All the dermatophyte isolates can grow at 37 °C. Microscopy of purulence sampling from intact nodules demonstrated abundant septate hyphae, and also isolation from purulence was concordance with skin tissue culture. Ultrasound-guided sampling from non-eroded can yield purulence, and direct microscopy of purulence may facilitate rapid diagnosis of deep dermatophytosis and serve to prevent disease progression and dissemination.

Terbinafine Resistant Trichophyton Indotineae Isolated in Patients With Superficial Dermatophyte Infection in Canadian Patients.

BACKGROUND: Trichophyton mentagrophytes type VIII (segregated as Trichophyton indotineae) is a new strain of antifungal resistant Trichophyton spp. that has been found in different countries around the world. This new strain has been found to be resistant to terbinafine. OBJECTIVES: We present the clinical characteristics, diagnosis and treatment approach of Canadian patients with mycology and molecular confirmation of superficial mycosis caused by T. indotineae. METHODS: Mycology testing from cultures and PCR were used to confirm T. indotineae. We collected clinical information from patients with a confirmed diagnosis. RESULTS: We report eight Canadian patients mainly presenting with extensive superficial mycosis due to T. indotineae. Three patients presented lesions on the face in addition to lesions on their body. Four patients were initially started on itraconazole or fluconazole, one patient was started on topical therapy, and three patients were referred to infectious disease. CONCLUSIONS: This new strain represents a dermatology and public health concern. Treatment guidelines are lacking. We include a practical approach and treatment recommendations for clinicians who will be encountering these emerging cases in Canada while waiting for evidence-based treatment guidelines.

Disseminated dermatophytosis and acquired immunodeficiency syndrome: literature review and presentation of clinical experience / Dermatofitose disseminada e síndrome da imunodeficiência adquirida: revisão de literatura e apresentação de experiência clínica

Introduction: Dermatophytosis are very common fungal infections caused by the fungal species Microsporum, Epidermophyton or Trichophyton, which mostly affect the skin, the interdigital region, groin and scalp. Although they do not cause serious diseases, in patients with the human immunodeficiency virus the infection manifests itself and evolves exuberantly, usually with extensive and disseminated lesions. Objective: To review the literature on dermatophytosis in people living with human immunodeficiency virus and to present the experience in clinical care in a patient living with human immunodeficiency virus with extensive and disseminated dermatophytosis. Methods: A literature review on the topic was carried out in the PubMed/National Library of Medicine ­ USA databases, using the keywords dermatophytosis, or dermatophytosis associated with the words AIDS, human immunodeficiency virus or immunodeficiency, from 1988­2022. The clinical experience showed a patient living with human immunodeficiency virus developing AIDS and presenting with disseminated skin lesions. Samples of the lesion were collected by scraping, which were submitted to culture and there was growth of fungi of the Trichophyton sp genus. A biopsy of the lesion was also performed using the Grocott-Gomori's Methenamine Silver stain. Results: We found 1,014 articles, of which only 34 presented a direct correlation with our paper, and were used to discuss the main themes narrated in this article. We present clinical experience in the management of a patient with human immunodeficiency virus/AIDS and low adherence to antiretroviral treatment, showing extensive and disseminated erythematous-squamous lesions with a clinical diagnosis of tinea corporis, manifesting with a clinical picture usually not found in immunocompetent patients. The diagnosis was confirmed by laboratory tests with isolation of the Trichophyton sp fungus. The patient was treated with oral fluconazole, with complete remission of the clinical picture after two months. She was also thoroughly encouraged to use the prescribed antiretroviral medication correctly. Conclusion: Dermatophytosis in patients living with human immunodeficiency virus can present extensive and disseminated forms. The antifungal treatment is quite effective, with remission of the condition. Antiretroviral therapy is an important adjuvant for better recovery of the sickness.

Introdução: Dermatofitoses são infecções comuns, causadas pelas espécies fúngicas Microsporum, Epidermophyton ou Trichophyton, que acometem preferencialmente a pele da região interdigital, da virilha e do couro cabeludo. Apesar de não causar doenças graves, em pacientes portadores do vírus da imunodeficiência humana, a infecção se manifesta e evolui de forma exuberante, normalmente com lesões extensas e disseminadas. Objetivo: Fazer revisão de literatura sobre dermatofitose em pessoas vivendo com vírus da imunodeficiência humana e apresentar a experiência na atenção clínica em uma paciente vivendo com o vírus e dermatofitose extensa e disseminada. Métodos: A revisão de literatura sobre o tema baseou-se nos dados do Pubmed/National Library of Medicine, dos Estados Unidos, utilizando-se as palavras-chave dermatofitose, dermatofitose e AIDS, dermatofitose e vírus da imunodeficiência humana, e dermatofitose e imunodeficiência, de 1988­2022. Descreveu-se a experiência clínica na abordagem de uma paciente vivendo com vírus da imunodeficiência humana, a qual desenvolveu AIDS e apresentou lesões cutâneas disseminadas. Por raspado, foram coletadas amostras da lesão e submetidas à cultura, e constatou-se crescimento de fungos do gênero Trichophyton sp. Realizou-se também biópsia da lesão, corada pelo método da metenamina de prata de Grocott-Gomori. Resultados: Foram encontrados 1.014 artigos, dos quais apenas 34 apresentaram correlação direta com nosso trabalho, e foram utilizados para discorrer sobre os principais temas narrados neste artigo. Apresentou-se experiência clínica na abordagem de uma paciente com vírus da imunodeficiência humana/AIDS e baixa adesão ao tratamento antirretroviral, exibindo lacerações eritematoescamosas extensas e disseminadas, com diagnóstico clínico de Tinea corporis, manifestando-se com quadro clínico usualmente não encontrado em pacientes imunocompetentes. O diagnóstico foi confirmado por exames laboratoriais com isolamento do fungo Trichophyton sp. Tratada com fluconazol via oral, a paciente apresentou remissão parcial das infecções aos dois meses e completa aos seis meses. Também foi exaustivamente estimulada a usar corretamente a medicação antirretroviral prescrita. Conclusão: A dermatofitose em pacientes com vírus da imunodeficiência humana pode se apresentar de forma extensa e disseminada. O tratamento antifúngico é eficaz, com remissão do quadro. A terapia antirretroviral é importante adjuvante para melhor recuperação dos enfermos
