A new paradigm in the management of scalp pruritus: findings from the SCALP-PR trial.

PURPOSE: The "Impact of scalp pruritus in dermatological consultations in Spain: The SCALP-PR trial" was initiated to address the common yet often insufficiently examined issue of scalp pruritus in dermatology. This condition leads to an uncontrollable urge to scratch, affecting the patients' quality of life and potentially causing scalp damage. This study aimed to explore the prevalence, patient profile, underlying conditios, and therapeutic approaches for scalp pruritus in Spain, and to assess the safety and efficacy profile, as well as the tolerability of a non-pharmacologic treatment. METHODS: From 2021 through 2022, 75 dermatologists enrolled a total of 359 patients in a study on scalp pruritus, approved by the Bellvitge University Hospital Research Ethics Committee, Barcelona, Spain. This evidence-based research combined a meta-analysis with observational study techniques focused on real-world evidence to examine the therapeutic impact on quality of life (QoL). Utilizing the Dermatology Life Quality Index (DLQI) for QoL assessments, the study evaluated the effectiveness of the topical product over 15 days. Data collection was conducted via an eCRF and analyzed with statistical methods to provide reliable insights into the management of scalp pruritus. RESULTS: The prevalence of scalp pruritus in Spain was found to be 6.9%, predominantly among women with a mean age of 52.5 years. The leading causes identified were seborrheic dermatitis and pruritus of undetermined etiology or sensitive scalp. Stress was noted as a key factor, with corticosteroids and hygienic measures being common therapies. The topical product demonstrated significant reductions in pruritus and scratching in more than 90% of patients after 15 days. Improvements were also seen in dermatological quality of life, with 87.1% of patients showing enhancements in DLQI scores. The product was well-received thanksto its cosmetic properties, with high ratings in texture, ease of application, and fragrance. CONCLUSION: The topical product studied is a safe, effective, and cosmetically appealing treatment, improving scalp pruritus in various etiologies for most patients. The results highlight the need for patient-center treatments in dermatology, providing important insights for clinical practice and future research.

Bishop Flap and Sigma Flap to Repair Surgical Defects in High-Tension Anatomical Regions. / Colgajo obispo y colgajo sigma para defectos quirúrgicos en zonas anatómicas de elevada tensión.

BACKGROUND: The reconstruction of surgical defects in high-tension anatomical regions is challenging due to the ischemia and subsequent necrosis associated with tension closure. Research on new flaps capable of closing these defects exerting less tension would be a tremendous advancement in dermatological surgery. PATIENTS AND METHODS: We conducted a multicenter, retrospective study that used 2 new flaps-the bishop and the sigma ones-to repair surgical defects in high-tension regions such as the scalp, lower extremities, and the nasal pyramid. The bishop flap was used in 9 patients, 5 of whom exhibited their lesion in the nasal pyramid, 2 in the legs and another 2 in the scalp. The sigma flap was used in 6 patients, 5 of whom exhibited scalp lesions and 1 leg lesion. RESULTS: Uneventful and excellent results were obtained in all 15 patients due to infection, dehiscence, or necrosis. CONCLUSIONS: Both the bishop and the sigma flaps are a good alternative to repair surgical defects in high-tension regions such as the scalp, lower extremities, or the nasal pyramid.

Carcinoma basocelular de la piel cabelluda tratado con HeberFERON. Seguimiento clínico, ecográfico e histopatológico

Fundamento: El carcinoma basocelular es infrecuente en la piel cabelluda. Es un tumor de invasión local y crecimiento lento, puede ser agresivo, destruir tejidos vecinos, causar ulceración e invadir en profundidad cartílago y hueso. Objetivo: Evaluar los resultados de la aplicación del HeberFERON y el seguimiento con ecografía cutánea en pacientes con carcinoma basocelular en la piel cabelluda. Metodología: Se realizó un estudio observacional, descriptivo y longitudinal en una serie de casos con diagnóstico de carcinoma basocelular de la piel cabelluda en el Policlínico Centro de la ciudad Sancti Spíritus, durante el período de 10 de julio del 2018 a 29 de julio del 2022. Se incluyeron 6 casos. Las variables estudiadas fueron la respuesta al tratamiento mediante la clínica, la ecografía cutánea e histopatología y presencia de eventos adversos. Resultados: Predominó el sexo masculino, subtipo histológico sólido, subtipo clínico nódulo ulcerativo, tamaño del tumor mayor de 30 mm y tiempo de evolución de más de 12 meses; la respuesta al tratamiento en la mayoría de los casos fue parcial. Los eventos adversos fueron dolor y ardor en el sitio de inyección, fiebre, edema y eritema perilesional. Conclusiones: El HeberFERON resultó de utilidad en los pacientes con carcinoma basocelular del cuero cabelludo ya que redujo el tumor en unos casos y en otros lo eliminó. La ecografía permitió la evaluación en tiempo real de la neoplasia; los eventos adversos más frecuentes fueron la fiebre y el dolor en el sitio de inyección, a pesar de ello ningún paciente abandonó el tratamiento.

Background: Basal cell carcinoma is uncommon in the scalp. It is a slow-growing locally invasive tumor, it can be aggressive in destroying neighboring tissues, cause ulceration and invade deep into the cartilage and bone. Objective: To evaluate the results of HeberFERON application and follow-up with cutaneous echographical in patients with scalp basal cell carcinoma. Methodology: An observational, descriptive and longitudinal study was conducted in a series of cases diagnosed with scalp basal cell carcinoma at the Center Polyclinic in Sancti Spíritus city during the period from July 10, 2018 to July 29, 2022. Six clinical cases were included. The studied variables were the answer to the treatment by clinical, cutaneous echographical and histopathology and the presence of adverse events. Results: Male sex predominated, solid histologic subtype, clinical subtype ulcerative nodule, tumor size greater than 30 mm and evolution time of over 12 months; the treatment response in most cases was partial; adverse events were pain and burning at the injection site, fever, edema and perilesional erythema. Conclusion: It was observed that in patients with scalp basal cell carcinoma, the HeberFERON treatment reduced in some cases and eliminated the tumor in others. Echography allowed real-time evaluation of the neoplasm, fever and pain at the injection site were the most frequent adverse events. In spite of this, none of the patients abandoned the therapy.

Background The Pacman flap is a modified V-Y advancement flap that showed to be versatile in repairing surgical and non-surgical wounds. Indeed, this flap has been used in any anatomical localization, except for the scalp, where its use has not been reported. Moreover, the versatility of the Pacman flap can be enhanced by applying simple modifications to its original design. Materials and methods A case-series of 23 patients whose surgical breaches were repaired using standard or modified Pacman flap were included in this retrospective study. Results Most patients were male (65.2%) with a median age of 75.7 years. Squamous cell carcinoma was the tumor most commonly removed (60.9%), while scalp and face were the most frequent localizations (30.4%). Although 18 flaps were sculpted in the traditional Pacman shape, 5 were modified to fit the defect and localization. Complications occurred in 30% of flaps, but all of them were minor except for 1 extended necrosis. Conclusions The Pacman flap can be used to repair surgical wounds localized in any body area, including the scalp. Three modifications can enhance the versatility of the flap and offer new repair options to dermatologic surgeons (AU)

Los pacientes con resultados positivos se diagnosticaron con tinea capitis (78,95 %), tinea faciei (15,79 %) y tinea corporis (10,52 %). El 75,43 % de los pacientes recibió tratamiento previo y de estos el 69,73 % fue con esteroides. El examen directo fue positivo en el 53,84 % y los cultivos en el 46,5 % de los casos. Los agentes aislados fueron: Microsporum canis (77,77 %), Trichophyton spp. (11,11 %), Trichophyton rubrum (5,55 %) y Malassezia spp. (5,55 %). Conclusión. Tinea capitis fue la presentación clínica más común y M. canis el dermatofito más frecuentemente aislado. Llamó la atención el uso de esteroides como primera y única opción del tratamiento empírico' lo cual resalta la importancia del diagnóstico microbiológico para proporcionar la terapia apropiada.

Introduction. Dermatophytoses are superficial fungal infections of the keratinized epithelium like tinea capitis. The latte mainly affects school-vulnerable populations. Carpinelo is a peripheral neighborhood in Medellín with poor socioeconomic conditions and where a suspected tinea capitis outbreak took place. Objective. To study and characterize, clinically and microbiologically, patients with suspected dermatophytosis in Carpinelo. Materials and methods. We carried out a descriptive and longitudinal study with an active case search of tinea capitis in children and their relatives from the Jardín Educativo Buen Comienzo community in Carpinelo. Patients were clinically evaluated, and samples of scales and hair were taken to perform mycological studies with a 10 % potassium hydroxide and culture in Sabouraud and Mycosel agar. We analyzed the data with the statistical program SPSS™. 25 version. Results. Fifty-seven individuals were studied: 47 were children with a mean age of six years and a ratio of 2:1 male to female. Patients with confirmed diagnosis presented the following clinical forms: tinea capitis (78.95%), tinea faciei (15.79%) or tinea corporis (10.52%). Out of the total, 69.76% of the patients had previous treatment with steroids. The direct test was positive in 53.84% of the samples, and 46.15% had positive cultures. The isolated species were: Microsporum canis (77.77%), Trichophyton spp. (11.11%), Trichophyton rubrum (5.55%), and Malassezia spp. (5.55 %). Conclusion.Tinea capitis was the most common clinical form, and M. canis was the most frequently isolated species. The use of steroids as the first and only option for empiric treatment was worth of notice. The findings of this study point out the importance of microbiological diagnosis in choosing the best treatment for the patients.

Brote de tinea capitis tricofítica en un grupo de niños escolares en un área rural del departamento del Cauca, Colombia / An outbreak of trichophytic tinea capitis in a group of schoolchildren in a rural area of the department of Cauca, Colombia

Introducción. La tiña de la cabeza es una micosis que se presenta en el tejido queratinizado, afecta al cuero cabelludo y puede causar alopecia, prurito y descamación. Este tipo de micosis es más frecuente en niños de edad escolar, por lo que puede desencadenar un problema de salud pública. En Colombia, los principales agentes etiológicos reportados son los dermatofitos zoofílicos. Objetivo. En el presente estudio se buscó caracterizar un brote de tinea capitis en 32 niños de un colegio de la zona rural del departamento del Cauca. Materiales y métodos. Se llevó a cabo una investigación epidemiológica de campo en la que se aplicó una encuesta estructurada para caracterizar aspectos sociodemográficos y factores predisponentes para su ocurrencia. Se recolectaron muestras de escamas de cuero cabelludo y cabellos afectados para estudios micológicos. Finalmente, por medio de la Secretaría Departamental del Cauca y del hospital local, se manejó el brote de tinea capitis y se hicieron recomendaciones a los niños, los padres de familia y la población en general para prevenir estas micosis. Este estudio contó con el consentimiento informado verbal por parte de los padres de familia y los niños. Resultados. El agente etiológico aislado en el 63 % de las muestras recolectadas fue Trichophyton tonsurans y el principal factor predisponente para esta micosis fue compartir máquinas rasuradoras (87,5 %). El agente etiológico de este brote de tinea capitis no inflamatoria fue un dermatofito antropofílico. Conclusión. Idealmente, se deben practicar los estudios micológicos con el fin de establecer el agente etiológico y, así, plantear las terapéuticas y recomendaciones según las guías de manejo. Además, se debe realizar un trabajo multidisciplinario para el control del brote y la educación de la población respecto a esta micosis.

Introduction. Tinea capitis is a mycosis of keratinized tissue, which affects the scalp and may cause alopecia, pruritus, and desquamation. This type of mycosis is more frequent in school-age children, and it may represent a public health problem; the main etiological agents reported for Colombia are zoophilic dermatophytes. Objective. To characterize an outbreak of Tinea capitis in 32 children from a rural school in the department of Cauca. Materials and methods. We conducted an epidemiological field study using a structured survey to characterize sociodemographic aspects and predisposing factors for this mycosis. We collected samples of affected scalp scales and hair for mycological studies. The children and the general population received recommendations, about these mycoses' prevention, from Cauca's health authorities and the local hospital. The parents verbally approved the informed consent. Results. The etiological agent isolated in 63% of the collected samples was Trichophyton tonsurans, an anthropophilic dermatophyte, and the main predisposing factor was sharing razors (87.5%). Conclusions. Ideally, mycological studies define the etiological agent to propose therapeutics and recommendations in agreement with management guidelines. Implementation of multidisciplinary measures to control the outbreak and educate the population is required.

Enfriamiento del cuero cabelludo para la prevención de la alopecia secundaria a quimioterapia: revisión sistemática y metanálisis / Scalp cooling for the prevention of chemotherapy-induced alopecia: systematic review and meta-analysis

Fundamentos: La alopecia es uno de los efectos adversos más comunes de la quimioterapia, con un impacto importante sobrela calidad de vida de los/las pacientes que la padecen. Entre las intervenciones disponibles para su prevención, el enfriamiento delcuero cabelludo (ECC) es la que cuenta con un uso más extendido. El objetivo de este estudio fue evaluar la eficacia y la seguridaddel uso de sistemas de ECC durante las sesiones de quimioterapia para la prevención o reducción de la extensión de la alopeciasecundaria a la quimioterapia. Métodos: Se llevó a cabo una revisión sistemática de la literatura publicada hasta noviembre de 2021. Se seleccionaron ensayosclínicos aleatorizados. La medida de resultado principal fue la alopecia (pérdida de cabello superior al 50%) durante y posteriormenteal tratamiento de quimioterapia. Cuando fue posible, se realizó síntesis cuantitativa de los resultados mediante metanálisis con elprograma Stata v.15.0. Se estimó el riesgo relativo (RR) de la variable alopecia, utilizando un modelo de efectos aleatorios siguiendoel método de Mantel-Haenszel. La heterogeneidad estadística de los resultados se evaluó gráficamente y mediante el test de la χ2 yel estadístico I2 de Higgins. Se realizaron análisis de sensibilidad y análisis de subgrupos. Resultados: Se incluyeron 13 estudios con un total de 832 participantes (97,7% de mujeres). En la mayoría de los estudios, losagentes quimioterapéuticos principales aplicados fueron las antraciclinas o la combinación de antraciclinas y taxanos. Los resultadosobtenidos indican que el ECC reduce la aparición de la alopecia un 43% frente al grupo control (RR=0,57; IC95%=0,46 a 0,69; k=9;n=494; I2=63,8%). No se encontró una diferencia estadísticamente significativa entre la eficacia de sistemas de enfriamiento auto-matizados y no automatizados (P=0,967). No se registraron eventos adversos graves a corto o medio plazo relacionados con el ECC...(AU)

Background: Alopecia is one of the most common adverse effects of chemotherapy, having a significant impact on the qualityof life of patients who suffer from it. Among the interventions available for its prevention, scalp cooling (SC) is the most widely used. The aim of this study was to assess the efficacy and safety of the use of SC systems during chemotherapy sessions for the preventionor the reduction of the extent of chemotherapy-induced alopecia.Methods: A systematic review of the literature published up to November 2021 was carried out. Randomized clinical trials were selected. The main outcome measure was alopecia (hair loss>50%) during and after chemotherapy treatment. When possible, a quantitative synthesisof the results was performed through meta-analysis using the Stata v.15.0 software. The risk ratio (RR) of the variable alopecia, was estimatedusing a random effects model following the Mantel-Haenszel method. Statistical heterogeneity of the results was evaluated graphically andthrough the test of heterogeneity χ2 and the Higgins I2 statistic. Sensitivity analyses and subgroup analyses were performed. Results: 13 studies were included, with a total of 832 participants (97.7% women). In most studies, the main chemotherapy treat-ment applied was anthracyclines or the combination of anthracyclines and taxanes. The results obtained indicate that SC preventsalopecia (loss>50%) by 43% compared to the control group (RR=0.57; 95% CI=0.46 to 0.69; k=9; n=494; I2=63.8%). No statisticallysignificant difference was found between the efficacy of automated and non-automated cooling systems (P=0.967). No serious short-or medium-term adverse events related to SC were recorded. Conclusions: The results suggest that scalp cooling contributes to the prevention of chemotherapy-induced alopecia.(AU)

Resumen Querión Celso es una micosis ocasionada por hongos dermatofitos que daña el cuero cabelludo principalmente a niños y en raras ocasiones a adultos. La forma de infección para los humanos proviene de los animales y del suelo y se relaciona con mala higiene personal, hacinamiento en las viviendas, condiciones de subdesarrollo y pobreza. Se presenta un caso de un niño de 9 años con una úlcera de 7 cm de diámetro en el cuero cabelludo y en forma de placa circular que presentaba material purulento, pelo quebradizo y un área alopécica. Al inicio, se abordó de manera terapéutica como una infección bacteriana; posteriormente, se solicitó estudio micológico que evidenció una coinfección por el microorganismo Microsporum gypseum. Se le confirmó el diagnóstico de tiña capitis con afección inflamatoria y se le prescribió griseofulvina, lo que resultó en una curación completa.

Abstract Kerion Celsi is a mycosis caused by dermatophyte fungi that mostly affects children and rarely adults, causing damage to the scalp. The form of infection for humans comes from animals and the soil. The infection is related to poor personal hygiene, overcrowded homes, underdeveloped conditions, and poverty. A case of a 9-year-old boy with a 7cm diameter ulcer on the scalp and in the form of a circular plaque that presented purulent material, brittle hair and an alopecic area is presented. Initially it was therapeutically addressed as a bacterial infection, a mycological study was requested, which showed coinfection by the microorganism Microsporum gypseum, the diagnosis of tinea capitis with inflammatory condition was confirmed, and Griseofulvin was prescribed, resulting in complete cure.

Cuero cabelludo sensible: diagnóstico y manejo práctico / Sensitive Scalp: Diagnosis and Practical Management

El cuero cabelludo sensible es una piel sensible de localización especial. Puede ser primario, cuando se presenta sin enfermedad del cuero cabelludo, y secundario cuando es atribuible a procesos como psoriasis, dermatitis seborreica, dermatitis atópica y otros. Las manifestaciones clínicas de la forma primaria son subjetivas. El escozor, picor, tricodinia y sensaciones disestésicas son el motivo de consulta, muy a menudo coincidiendo con alopecia. Clínicamente la piel del cuero cabelludo puede ser normal o eritematosa. No hay datos de laboratorio o histológicos específicos para un diagnóstico objetivo. Los factores desencadenantes son endógenos como el estrés y alteraciones emocionales y psicopatológicas, o ambientales como los tópicos inadecuados y los cosméticos. El tratamiento debe ser personalizado, incluyendo pimecrólimus, la hidratación con ácido hialurónico, y la mesoterapia con plasma rico en factores de crecimiento (AU)

Sensitive scalp is sensitive skin located on the scalp. Sensitivity is considered primary in the absence of an associated scalp disorder and secondary when caused by conditions such as psoriasis, seborrheic dermatitis, and atopic dermatitis. The clinical manifestations of primary sensitive scalp are subjective. Common presenting symptoms are burning, itching, trichodynia, and dysesthesia, often coinciding with hair loss. Clinically, the skin appears normal or red. An objective diagnosis based on laboratory or histologic findings is not possible. Triggers may be endogenous (e.g., stress and emotional or psychopathological disturbances) or exogeneous (e.g., topical products and cosmetics). Treatment must be individualized. Options include pimecrolimus, hydration with hyaluronic acid, and mesotherapy with plasma rich in growth factors (AU)

Procedimentos estéticos com ênfase na queda capilar / Aesthetic procedures with emphasis on hair loss / Procedimientos estéticos con énfasis en la caída del cabello

A beleza está diretamente ligada ao aspecto dos cabelos, em todos os tempos e todas as culturas. O cabelo ao longo da vida é sujeito a vários tipos de mudanças, sejam elas naturais ou artificiais, conduzidas por uma vontade de mudar, muitas vezes, seja por representar uma nova fase, como também é símbolo de autocuidado, vaidade, sucesso, possuem significativa importância na aparência e autoestima das pessoas e, por isso, a queda capilar pode atingir a qualidade de vida do indivíduo. Neste sentido, o objetivo deste estudo foi avaliar procedimentos estéticos minimamente invasivos e não cirúrgicos com ênfase na queda capilar. Para tanto, foi realizada uma revisão bibliográfica integrativa, de caráter descritivo nas principais bases de dados em saúde: SciELO, Google Acadêmico, PubMed e livros de medicina, nos idiomas português, inglês e espanhol, considerando o período de 2007 a 2022. De acordo com o último censo da Sociedade Brasileira de Dermatologia, a queixa de alopecia está entre as dez mais frequentes nos consultórios dermatológicos. As doenças capilares mais importantes estão divididas em dois grupos, as cicatriciais quando a perda de cabelo é acompanhada por cicatrizes resultando em calvície permanente, e as não cicatriciais onde a calvície não é permanente levando a diminuição e o afinamento gradual do cabelo. A alopecia não cicatricial é a mais frequente e as mais comuns entre elas são a alopecia androgenética e o eflúvio telógeno. Muitos pacientes procuram tratamento para melhorar a aparência e a autoestima, que podem estar relacionados a quadros de ansiedade e depressão. Esses tratamentos devem ser individualizados, onde se deve avaliar as características individuais de cada paciente. Os tratamentos capilares estéticos podem contribuir de forma significativa para a redução da baixa autoestima, contribuindo para recuperação da autoconfiança através do crescimento capilar proporcionado pela estética. Sendo assim, conclui-se que os resultados coletados na revisão de literatura foram satisfatórios, de forma onde mostra que os medicamentos, suplementos e tratamentos estéticos na queda capilar vem evoluindo cada vez mais. Contudo, mais estudos acerca do assunto são necessários.

Beauty is directly linked to the appearance of hair, in all times and all cultures. Hair throughout life is subject to various types of changes, whether natural or artificial, driven by a desire to change, often because it represents a new phase, as it is also a symbol of self-care, vanity, success, they have significant importance in people's appearance and self-esteem and, therefore, hair loss can affect the individual's quality of life. In this sense, the objective of this study was to evaluate minimally invasive and non- surgical aesthetic procedures with an emphasis on hair loss. To this end, an integrative bibliographic review was carried out, of a descriptive nature, in the main health databases: SciELO, Google Scholar, PubMed and medical books, in Portuguese, English and Spanish, considering the period from 2007 to 2022. According to the latest census by the Brazilian Society of Dermatology, the complaint of alopecia is among the ten most frequent complaints in dermatological offices. The most important hair diseases are divided into two groups, scarring when hair loss is accompanied by scars resulting in permanent baldness, and non-scarring where baldness is not permanent leading to gradual thinning and thinning of the hair. Non-scarring alopecia is the most frequent and the most common among them are androgenetic alopecia and telogen effluvium. Many patients seek treatment to improve their appearance and self-esteem, which may be related to anxiety and depression. These treatments must be individualized, where the individual characteristics of each patient must be evaluated. Aesthetic hair treatments can contribute significantly to reducing low self-esteem, contributing to the recovery of self-confidence through hair growth provided by aesthetics. Therefore, it is concluded that the results collected in the literature review were satisfactory, in a way that shows that medicines, supplements and aesthetic treatments in hair loss have been evolving more and more. However, more studies on the subject are needed.

Trichoscopy in Alopecia Areata. / Tricoscopia en la alopecia areata.

Alopecia areata is an autoimmune disease that affects the hair follicle and can present as bald patches on the scalp and hair loss in other parts of the body. Diagnosis is clinical but can be aided by trichoscopy, a simple, rapid technique that reduces the need for invasive procedures and can also help with monitoring treatment response. We review the usefulness of trichoscopy in alopecia areata. The most common trichoscopic findings are yellow dots, black dots, exclamation mark hairs, short vellus hairs, and coudability hairs. Other, less common, findings can also help establish a diagnosis. Good response to treatment is indicated by the disappearance of black dots, broken hairs, and exclamation mark hairs. The observation of yellow dots, by contrast, indicates chronic disease and poor response to treatment.

Metastasis of malignant pleural mesothelioma to the scalp following chemotherapy: A case report and review of the literature.

Malignant pleural mesothelioma is a neoplasm involving mesothelial cells of the pleura. Both local and distant metastases may develop, although the latter are less common and it is extremely rare for cutaneous metastases to appear as a solitary lesion on the scalp. We present the case of a 54-year-old woman with a 2-year history of unresectable left pleural mesothelioma treated with chemotherapy, who had developed a painful lump on the scalp one month prior to consultation. Skin metastases of mesothelioma must be differentiated from primary neoplasms, and immunohistochemistry is fundamental to determine the origin of such lesions, which can be correctly identified through the use of a panel of markers.

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.
