ABSTRACT

Los inhibidores de checkpoint (ICP) son anticuerpos usados en inmunoterapia contra el cáncer. Uno de sus blancos de acción es el receptor de muerte celular programada-1 (PD-1), el cual es importante para mantener la tolerancia inmunitaria. Sin embargo, este mecanismo se asocia a riesgo de eventos adversos relacionados a la inmunidad que pueden afectar a múltiples órganos incluyendo el sistema endocrino. Se describe el caso inhabitual de un paciente que a los 18 meses de terapia con ICP debutó con cetoacidosis diabética (CAD).


Immune checkpoint inhibitors consist in antibodies used in immunotherapy against cancer. One of their targets is the programmed cell death-1 (PD-1) receptor, which is important in maintaining self-tolerance. However, this mechanism is associated with a risk for immune-related adverse events potentially affecting multiple organs, including the endocrine system. We describe the unusual case of a patient who, after 18 months of treatment with an immune checkpoint inhibitor, debuted with diabetic ketoacidosis

ABSTRACT

Squamous cell carcinoma (SCC) is a non-melanoma skin cancer, with chronic sun exposure as the main risk factor. Excisional surgery is the most indicated treatment; however, patients can suffer functional, aesthetic, and psychological damage depending on the lesion site. Topical administration of 7,12-dimethylbenz[a]anthracene (DMBA) and 12-O-Tetradecanoylphorbol-13- acetate (TPA) induce to the appearance of benign skin tumors in mice, some of which develop into SCC. This protocol has been used to analyze the effects of many chemopreventive agents that may block or inhibit the mechanisms of action of chemical carcinogenesis. We compared the effects of chemopreventive agents in an induced skin carcinogenesis animal model. In the Scopus, PubMed, and EMBASE databases, we searched for manuscripts published between June 16, 2011, and June 16, 2021. We excluded studies conducted in vitro or on transgenic mice; in addition, studies without drug dosage, route of administration, or tumor incidence were excluded. We selected 26 studies and analyzed their main characteristics and the outcomes of tumorigenesis analysis. Most chemopreventive agents have shown excellent potential to inhibit the development of skin tumors. This review also discusses the standardization of studies in animal models to ensure better responses and future randomized clinical trials for cancer treatment and prevention.


O carcinoma espinocelular cutâneo (CEC) é um câncer de pele não melanoma, com a exposição solar crônica como o principal fator de risco. A cirurgia excisional é o tratamento mais indicado; entretanto, os pacientes podem sofrer danos funcionais, estéticos e psicológicos dependendo do local da lesão. A administração tópica de 7,12-dimetilbenz[a]antraceno (DMBA) e 12-O- Tetradecanoilforbol-13-acetato (TPA) induz ao aparecimento de tumores cutâneos benignos em camundongos, alguns dos quais evoluíram para CEC. Este protocolo tem sido utilizado para analisar os efeitos de muitos agentes quimiopreventivos que podem bloquear ou inibir os mecanismos de ação da carcinogênese química. Comparamos os efeitos de agentes quimiopreventivos em um modelo animal que foi induzido à carcinogênese de pele. Nas bases de dados Scopus, PubMed e EMBASE, buscamos manuscritos publicados entre 16 de junho de 2011 e 16 de junho de 2021. Excluímos estudos realizados in vitro ou em camundongos transgênicos; além disso, estudos sem dosagem de drogas, via de administração ou incidência de tumores foram excluídos. Selecionamos 26 estudos e analisamos suas principais características e os resultados da análise da tumorigênese. A maioria dos agentes quimiopreventivos tem demonstrado excelente potencial para inibir o desenvolvimento de tumores cutâneos. Esta revisão também discute a padronização de estudos em modelos animais para garantir melhores respostas e futuros ensaios clínicos randomizados para tratamento e prevenção do câncer.


El carcinoma de células escamosas (CCE) es un cáncer de piel no melanoma, cuyo principal factor de riesgo es la exposición crónica al sol. La cirugía de escisión es el tratamiento más indicado; sin embargo, los pacientes pueden sufrir daños funcionales, estéticos y psicológicos dependiendo de la localización de la lesión. La administración tópica de 7,12-dimetilbenz[a]antraceno (DMBA) y 12-O-Tetradecanoilforbol-13-acetato (TPA) inducen a la aparición de tumores cutáneos benignos en ratones, algunos de los cuales se convierten en CCE. Este protocolo se ha utilizado para analizar los efectos de muchos agentes quimiopreventivos que pueden bloquear o inhibir los mecanismos de acción de la carcinogénesis química. Comparamos los efectos de los agentes quimiopreventivos en un modelo animal de carcinogénesis cutánea inducida. En las bases de datos Scopus, PubMed y EMBASE, se buscaron los manuscritos publicados entre el 16 de junio de 2011 y el 16 de junio de 2021. Se excluyeron los estudios realizados in vitro o en ratones transgénicos; además, se excluyeron los estudios sin dosis de fármacos, vía de administración o incidencia tumoral. Se seleccionaron 26 estudios y se analizaron sus características principales y los resultados del análisis de la tumorigénesis. La mayoría de los agentes quimiopreventivos han mostrado un excelente potencial para inhibir el desarrollo de tumores cutáneos. Esta revisión también analiza la estandarización de los estudios en modelos animales para garantizar mejores respuestas y futuros ensayos clínicos aleatorios para el tratamiento y la prevención del cáncer.

ABSTRACT

Los hemangiomas infantiles (HI) son los tumores benignos más frecuentes de la infancia; la variante segmentaria es rara y se asocia con un mal pronóstico. Una de sus principales complicaciones es la ulceración durante la fase de crecimiento del tumor, a pesar de no presentar características macroscópicas compatibles con una lesión agresiva. El manejo en estos casos es dificultoso e impone la necesidad de asociar múltiples estrategias, algunas orientadas específicamente a impedir la proliferación del hemangioma y otras orientadas a la curación de la herida, el manejo del dolor y la prevención de la infección agregada. Presentamos dos casos a fin de comunicar nuestra experiencia respecto del manejo de dicha patología y su evolución final.


Infantile hemangiomas (IHs) are the most common benign tumors of childhood, and segmental ones are rare and associated with a poor prognosis. While these tumors look harmless, one of their main related complications is ulceration during tumor growth. The management in these cases is extremely challenging, requiring a combination of multiple approaches, some specifically aimed at preventing the proliferation of the hemangioma and others aimed at wound care, pain management, and prevention of further infection. Here we discuss two cases to narrate our experience on the management of this condition and its outcome.

ABSTRACT

ABSTRACT Cemiplimab is a novel programmed death-1 inhibitor recently approved for advanced cutaneous squamous cell carcinoma. Immune-related adverse events derived from cemiplimab are similar to other anti-PD-1 drugs, including gastrointestinal and cutaneous toxicities. Oral immune-related adverse events were not reported with cemiplimab in previous studies; thus this case report warns of the fact that the oral cavity may be a site of immune-related adverse events during programmed death-1 block therapy and that this can lead to significant limitations when not properly treated. The present report describes the case of a patient with locally advanced cutaneous squamous cell carcinoma metastatic to cervical lymph nodes who developed dysphagia due to large and painful oral ulcers after a single dose of cemiplimab. The patient also exhibited a sarcoid-like reaction in mediastinal lymph nodes. No immune-related adverse events were found in any other organs. The oral lesions showed significant improvement after topical and short-course systemic corticosteroids, and low-level laser therapy was also performed in the oral lesions. The patient achieved a near-complete response and treatment was discontinued. This article discusses in detail the clinical outcomes and oral toxicity management of cemiplimab therapy for cutaneous squamous cell carcinoma.

ABSTRACT

ABSTRACT MEK- and BRAF-inhibitors trametinib and dabrafenib are successfully used for BRAF-mutated, metastasizing melanoma, but these compounds may induce side effects. We report a 50 years old female with BRAF-mutated metastasizing melanoma who received trametinib (2 mg/d) and dabrafenib (200 mg/d) after using interferon without benefit. Shortly after starting trametinib/dabrafenib, she experienced an inability to abduct the left eye. Eight days after starting this therapy the patient experienced loss of appetite, vomiting, diarrhea, vertigo, and fever of 40°C. Two days later she experienced visual loss, requiring permanent support for her daily activities. Two further days later myoglobinuria appeared in the absence of myalgias or muscle weakness but accompanied by marked tiredness and inactivity. She could not eat or drink during four days prior to admission. The patient suspected an adverse effect of trametinib/dabrafenib and discontinued it 2 days prior to admission. Thereafter, she experienced an almost complete remission of the deficits except for ocular muscle weakness and visual impairment.


Los inhibidores de MEX and BRAF como trametinib y dabrafenib se usan en el melanoma metastásico con mutación BRAF, pero pueden tener efectos secundarios. Informamos una paciente de 50 años con un melanoma metastásico con la mutación BRAF que recibió trametinib (2 mg/día) y dabrafenib (200 mg/día) después de usar interferón sin beneficio. Después de iniciar esta terapia la paciente notó una incapacidad de abducir el ojo izquierdo. Ocho días después de iniciar el tratamiento, tuvo falta de apetito, vómitos, diarrea, vértigo y fiebre de 40°C. Dos días después notó pérdida de su agudeza visual, requiriendo asistencia para efectuar sus actividades de vida diaria. Dos días después apareció coluria, en ausencia de mialgias o debilidad muscular, pero acompañadas de fatiga. Ella no pudo comer o tomar líquidos por cuatro días antes de ingresar al hospital. La paciente sospechó que estaba experimentando efectos secundarios de los medicamentos y los suspendió dos días antes del ingreso, experimentando una casi completa remisión de sus síntomas, con excepción de la debilidad de musculatura ocular y déficit visual.

ABSTRACT

Abstract Biological therapies, including anti-TNF agents, are important in the treatment of various chronic inflammatory diseases, including psoriasis, rheumatoid arthritis or inflammatory bowel disease. The increased use of these drugs translates into an increasing awareness of its adverse effects, which include malignancy. In this paper, we describe the case of a 28-year-old woman who developed a spitzoid melanocytic tumor after starting infliximab therapy for ulcerative colitis. The evidence for causality between anti-TNF and melanocytic proliferations is still sparse; nonetheless, treatment-associated immunosuppression seems to play a key role in this phenomenon. Therefore, a regular follow-up with a rigorous skin examination is essential in these patients. Noninvasive techniques such as dermoscopy or reflectance confocal microscopy are particularly useful diagnostic tools in these circumstances.

ABSTRACT

Introducción: cada año se reportan en el mundo entre dos y tres millones de nuevos casos del carcinoma basocelular, el cual puede tratarse de diversas formas, en dependencia de la variedad clínica, localización y tamaño de la lesión. Existen antecedentes del empleo exitoso del HeberFERON® como alternativa terapéutica para este tipo de cáncer cutáneo. Objetivo: caracterizar clínica y epidemiológicamente a los pacientes con carcinoma basocelular tratados con HeberFERON® en el Hospital Docente Clínico Quirúrgico "Dr. Miguel Enríquez", de la provincia de La Habana. Método: se realizó un estudio observacional, descriptivo y transversal dirigido a caracterizar los pacientes con carcinoma basocelular tratados con HeberFERON®, durante el período comprendido entre enero de 2017 a diciembre de 2018. El universo estuvo constituido por 49 pacientes, no se utilizó muestra. Resultados: predominó el sexo masculino, la edad máxima encontrada fue de 96 años, el fototipo cutáneo II fue el que prevaleció, mientras que el lugar de residencia habitual fue la urbana. Se encontró que, del total de casos estudiados, 47, eran tumores primarios para un 95,91 %; la localización más frecuente fue en las mejillas y 40 pacientes recibieron tratamiento previo con criocirugía, representando el 81,63 %. Conclusiones: la hipertensión arterial fue la enfermedad de base que predominó. El subtipo clínico más frecuente fue el nodular, al igual que el histológico. La respuesta al tratamiento fue favorable en la mayoría de los casos tratados con HeberFERON®.


Introduction: between two and three million new cases of basal cell carcinoma are reported worldwide each year, which can be treated in various ways, depending on the clinical variety, location and size of the lesion. There is a history of successful use of HeberFERON® as a therapeutic alternative for this type of skin neoplasm. Objective: to characterize clinically and epidemiologically the patients with basal cell carcinoma treated with HeberFERON® at the "Dr. Miguel Enríquez" Clinical Surgery Teaching Hospital in Havana. Method: an observational, descriptive and cross-sectional study was conducted to characterize patients with basal cell carcinoma treated with HeberFERON®, during the period January 2017 to December 2018. The universe consisted of 49 patients, no sample was used. Results: males predominated, the maximum age found was 96 years, skin phototype II prevailed, while the usual place of residence was urban. It was found that of the total of cases studied, 47 were primary tumors (95.91%), the most frequent location was on the cheeks and 40 patients received previous treatment with cryosurgery representing 81.63%. Conclusions: the predominant underlying disease was high blood pressure. The most common clinical subtype was nodular, as well as the histological one. The response to treatment was favorable in most of the cases treated with HeberFERON®.

ABSTRACT

Resumen Introducción: Los linfomas cutáneos primarios son un grupo heterogéneo de neoplasias de células T y B que se presentan en la piel, sin ninguna evidencia de enfermedad extracutánea en el momento del diagnóstico, y muestran diferencias considerables en histologia, fenotipo y pronóstico. Se consideran neoplasias poco frecuentes. Casos clínicos: Se presentan cinco casos de linfomas cutáneos diagnosticados en el Hospital Infantil de México Federico Gómez durante el periodo de 2010 a 2018. Las presentaciones clínicas más frecuentes en estos pacientes fueron dermatitis, costras hemáticas y úlceras necróticas. El inmunofenotipo más común fue el linfoma cutáneo no Hodgkin T/NK extranodal nasal primario. El esquema de tratamiento que se utilizó en la mayoría de los pacientes fue SMILE. El promedio de tiempo al diagnóstico fue de 7 meses. Conclusiones: El pronóstico depende del estadio de la enfermedad al diagnóstico, grado de afectación de la piel y presencia o ausencia de enfermedad extracutánea. Los linfomas cutáneos primarios son neoplasias poco frecuentes. Debido al diagnóstico tardío, el estadio de la enfermedad suele ser avanzado, por lo que, generalmente, el comportamiento es agresivo.


Abstract Background: Primary cutaneous lymphomas are a rare heterogeneous group of T and B cell skin neoplasms without any evidence of extracutaneous disease at the time of diagnosis, which show considerable differences in histology, phenotype and prognosis. Case reports: Five cases of cutaneous lymphomas treated at the Hospital Infantil de México Federico Gómez from 2010 to 2018 are described. The most frequent clinical presentations in these patients were dermatitis, blood scabs, and necrotic ulcers. The most common immunophenotype was non-Hodgkin T/NK primary nasal extranodal cutaneous lymphomas. The treatment scheme used in most patients was SMILE. The average time to diagnosis was 7 months. Conclusions: The prognosis depends on the stage of the disease at diagnosis, the degree of skin involvement, and the presence of extracutaneous disease. As primary cutaneous lymphomas are infrequent neoplasms, the stage of the disease is usually advanced and generally shows an aggressive behavior due to a late diagnosis.

ABSTRACT

Las terapias target constituyen hoy en día una alternativa terapéutica cada vez más utilizada para el manejo de pacientes con melanoma metastásico. Sin embargo, se han descrito múltiples efectos farmacológicos adversos asociados a su uso, siendo los cutáneos los de mayor prevalencia. Se presenta el caso de un hombre de 55 años con diagnóstico de melanoma cutáneo metastásico etapa IV, BRAFV600E mutado, en tratamiento con dabrafenib/trametinib que consultó por desarrollo de lesiones nodulares eritematosas sensibles en extremidades superiores e inferiores, asociadas a sensación febril durante el curso del tratamiento. Se descartó alguna infección sobreagregada. Se realizó una biopsia de las lesiones cutáneas, con confirmación diagnóstica histopatológica de una paniculitis mixta de predominio septal, granulomatosa y con vasculitis leucocitoclástica. La paniculitis asociada a esta terapia ha sido descrita en la literatura y se ha considerado un efecto farmacológico inmunomediado adverso, relacionándose a un mejor pronóstico para el melanoma metastásico en tratamiento. Por lo tanto, así como en el caso presentado, se evita la suspensión del fármaco y se asocia terapia sintomática en caso de mayores molestias del paciente. Es de alta relevancia para el dermatólogo conocer e interpretar adecuadamente este efecto adverso farmacológico, y así indicar el manejo más adecuado para el paciente.


Target therapies are currently a therapeutic option increasingly used for the management of patients with metastatic melanoma. However, there are multiple adverse pharmacological effects associated with their use that have been described. Cutaneous adverse reactions are the most frequent. We report the case of a 55-year-old man with a diagnosis of stage IV BRAFV600E-mutated metastatic cutaneous melanoma undergoing treatment with dabrafenib/trametinib, who consulted due to the development of erythematous nodular lesions in the upper and lower limbs associated with febrile sensation during the course of treatment. Infection was ruled out and a biopsy of the skin lesions was done, which provided the histopathological confirmation of a predominantly septal, granulomatous with leukocytoclastic vasculitis, mixed panniculitis. Panniculitis associated with this therapy has been described in the literature and has been considered an immune-mediated pharmacological adverse effect. It is considered to be related to a better prognosis in the treatment of metastatic melanoma. Consequently, as shown in this case report, target therapy should not be discontinued and symptomatic medication should be given to alleviate patient discomfort. The dermatologist should know and properly interpret this adverse effect and prescribe the most appropriate management for the patient.

ABSTRACT

Abstract Primary male genital melanomas are very rare; they are associated with high mortality and late detection. Scrotal melanoma is the least common presentation and only 23 cases have been reported. Herein, the authors present a 30-year-old patient with stage IIIC (T4b, N2a, M0) scrotal melanoma in order to report the characteristics, treatment, and outcome, as well as to emphasize the importance of examination of the genitals, education of patients about self-examination and destigmatizing genital lesions to increase the likelihood of earlier detection.

ABSTRACT

Abstract Confluent and reticulated papillomatosis of Gougerot and Carteaud is a rare dermatosis with onset during puberty, more prevalent in females than in males. The pathogenesis is unknown, but some theories suggest either a keratinization or endocrine disorder. The lesions are verrucous, brownish, hyperkeratotic papules or spots that coalesce in a confluent and/or reticulated pattern. This report presents a case with extensive cutaneous involvement associated with acanthosis nigricans and good response to treatment with methotrexate.

ABSTRACT

ABSTRACT Objective: To present the outcomes of fixed doses of propranolol tablets for the treatment of hemangiomas. Case description: Two illustrative cases of hemangioma in infant patients younger than six months old are described. Treatments were started in 2010 and 2011 and were monitored until August 2017. Patients were treated with fixed doses, initially calculated based on the upper limit of 3 mg/kg/day and administrated in two daily doses rounded down to the nearest multiple of five milligrams. Dosage was not adjusted to patients' weight gain. The tablets were crushed and then diluted in a maximum amount of 3 mL of water. This procedure was necessary because propranolol was not available in oral solution in 2009, when dosages available in the Brazilian market were 10, 40 and 80 mg. Both patients presented significative improvement in the first 60 days and were in complete remission by the end of the treatment. Comments: It is possible to treat patients with Propranolol 10 mg tablets, even though the dosage is not as precise as when calculated according to patients' weight. The maintenance of a fixed dose, ignoring the patient's progressive weight gains, helps avoiding the rebound effect and decreases complications.


RESUMO Objetivo: Apresentar a experiência com a utilização de propranolol em doses fixas, em forma de comprimido, para o tratamento de hemangiomas. Descrição do caso: Dois casos ilustrativos de portadores de hemangiomas com menos de seis meses de idade são descritos. O início de tratamento ocorreu nos anos de 2010 e 2011 com seguimento até agosto de 2017. Os pacientes foram tratados com doses fixas iniciais calculadas com limite máximo de 3 mg/kg/dia, divididas em duas doses diárias, sempre com quantidades múltiplas de 5 mg. Os comprimidos de 10 mg ou a sua metade eram macerados e diluídos em 3 mL de água. As doses não foram mais alteradas. Esse uso foi decorrente da ausência da forma líquida de propranolol em 2009, quando começamos a utilizar esse tratamento, sendo então apenas disponíveis comprimidos de 10, 40 e 80 mg. Os pacientes obtiveram melhora acentuada nos primeiros 60 dias e remissão completa posteriormente. Comentários: É possível o uso de comprimidos de 10 mg, apesar de resultar numa dose não exata, como a calculada por kg/peso. A manutenção da mesma dose, mesmo com aumento progressivo de peso, pode evitar o efeito rebote e diminuir o índice de complicações.

ABSTRACT

RESUMEN Fundamento: El carcinoma basocelular es el cáncer de piel no melanoma más frecuente, es un tumor de invasión local y crecimiento lento; su origen son las células epidérmicas de los folículos pilosos o las células basales de la epidermis; en ocasiones puede sufrir un crecimiento incontrolado, no responder a los tratamientos y ser causa de deformidad; las radiaciones ultravioletas son el principal factor en la génesis de esta enfermedad. Objetivo: Describir los resultados de la aplicación de HeberFERON en una serie de casos con carcinoma basocelular del rostro. Metodología: Se realizó un estudio observacional, descriptivo longitudinal en una serie de 32 casos clínicos de carcinoma basocelular del rostro que acudieron a la consulta de dermatología del Policlínico Centro. Se incluyeron aquellos con diagnóstico clínico, dermatoscópico e histopatológico. Se realizó una evaluación inicial, durante el tratamiento y 16 semanas después del mismo, se le administró 10.5 UI de HeberFERON 3 veces por semana hasta completar 9 dosis. Las variables fueron la respuesta al tratamiento y presencia o no de eventos adversos. Resultados: Predominó el sexo masculino, la piel blanca y la localización de la neoplasia en la nariz, se logró respuesta completa en la mayoría de los pacientes. Como eventos adversos se presentaron dolor en el sitio de inyección, fiebre y malestar general. Conclusiones: La respuesta objetiva al tratamiento fue favorable en la mayoría de los pacientes tratados con HeberFERON.


ABSTRACT Background: Basal cell carcinoma is the most frequent non-melanoma skin cancer, it is a tumor of local invasion and slow growth; it has its origin from the epidermal cells of the hair follicles or the basal cells of the epidermis; sometimes it can suffer uncontrolled growth, not respond to treatments and cause deformity; ultraviolet radiation is the main factor in the genesis of this disease. Objective: To describe the results of the application of HeberFERON in a series of cases with basal cell carcinoma of the face. Methodology: An observational, longitudinal descriptive study was carried out in a series of 32 clinical cases of basal cell carcinoma of the face that attended the dermatology office of the Polyclinic Center. Those with clinical, dermatoscopic and histopathological diagnosis were included. An initial evaluation was carried out, during the treatment and 16 weeks after it, 10.5 IU of HeberFERON was administered 3 times per week until 9 doses were completed. The variables were the response to treatment and the presence or absence of adverse events. Results: Male sex, white skin and the location of the neoplasm in the nose predominated; a complete response was achieved in most patients. Adverse events presented pain at the injection site, fever and malaise. Conclusions: The objective response to treatment was favorable in the majority of patients treated with HeberFERON.

ABSTRACT

Objetivo: estimar o impacto orçamentário incremental da terapia-alvo para tratamento de primeira linha do melanoma avançado não cirúrgico e metastático, em comparação à dacarbazina. Métodos: análise de impacto orçamentário na perspectiva do Sistema Único de Saúde (SUS) do Brasil; a partir de dados demográficos e estimativas da incidência, foi delimitada a população no horizonte temporal de três anos (2018-2020) e estimados os custos diretos médicos; foi considerado cenário de referência o tratamento com dacarbazina, e como cenários alternativos a terapia-alvo com vemurafenibe, dabrafenibe, vemurafenibe + cobimetinibe e dabrafenibe + trametinibe; a avaliação das incertezas foi conduzida mediante análise por cenários. Resultados: o impacto orçamentário incremental variou de R$ 451.867.881,00 a R$ 768.860.968,00, representando 0,70 a 1,53% dos gastos anuais totais com medicamentos ambulatoriais no SUS; no melhor e no pior cenário, os resultados variaram de R$ 289.160.835,00 a R$ 1.107.081.926,00. Conclusão: a terapia-alvo, comparada à dacarbazina, implica impacto excessivo no orçamento, desfavorecendo eventual incorporação.


Objetivo: estimar el impacto presupuestario incremental de la terapia dirigida para tratamiento de primera línea del melanoma avanzado no quirúrgico y metastásico comparado con la dacarbazina. Métodos: análisis de impacto presupuestario, en la perspectiva del Sistema Único de Salud (SUS) de Brasil; a partir de datos demográficos y estimaciones de incidencia se delimitó la población en un horizonte temporal de tres años (2018-2020) y se estimaron los costos directos médicos. El escenario de referencia fue el tratamiento con dacarbazina y los escenarios alternativos la terapia dirigida con vemurafenib, dabrafenib, vemurafenib + cobimetinib y dabrafenib + trametinib; la evaluación de incertidumbre se llevó a cabo mediante análisis por escenarios. Resultados: el impacto presupuestario incremental varió de R$ 451.867.881,00 a R$ 768.860.968,00, representando 0,70 a 1,53% de gastos anuales totales con medicamentos de ambulatorios en el SUS; en el mejor y el peor escenario los resultados variaron de R$ 289.160.835,00 a R$ 1.107.081.926,00. Conclusión: el uso de terapia dirigida comparado a la dacarbazina implica en impacto excesivo en el presupuesto, desfavoreciendo una eventual incorporación.


Objective: to estimate the incremental budget impact of target therapy for first-line treatment of advanced non-surgical and metastatic melanoma compared to dacarbazine treatment. Methods: budget impact analysis, from the Brazilian National Health System (SUS) perspective; based on demographic data and incidence estimates, the population over a three-year time horizon (2018-2020) was delimited and the direct medical costs were estimated; the reference scenario was treatment with dacarbazine, and the alternative scenarios were target therapy with vemurafenib, dabrafenib, vemurafenib + cobimetinib and dabrafenib + trametinib; uncertainty assessment was conducted through scenario analysis. Results: the incremental budget impact ranged from R$ 451,867,881.00 to R$ 768,860,968.00, representing 0.70 to 1.53% of total SUS annual outpatient drugs expenditure; in best and worst scenario, results ranged from R$ 289,160,835.00 to R$ 1,107,081,926.00. Conclusion: the use of target therapy compared to dacarbazine implies an excessive impact on the budget, this bring unfovorable to its possible incorporation.

ABSTRACT

El Vemurafenib es un inhibidor de la enzima serina/treonina quinasa BRAF utilizado en el tratamiento de pacientes con melanoma con diseminación loco-rregional y enfermedad metastásica, portadores de la mutación V600E del gen BRAF. Se ha asociado a múltiples efectos adversos cutáneos de los cuales se destaca la posibilidad de generar cambios en los nevos melanocíticos, aparición de nuevos nevos e incluso de segundos melanomas. El seguimiento digital dermatoscópico con mapeo corporal, ha demostrado utilidad en el diagnóstico precoz de melanoma.Presentamos dos casos clínicos de pacientes con ante-cedentes de melanoma en tratamiento con inhibido-res de BRAF (BRAFi) e inhibidores de BRAF y MEK (MEKi) en quienes se realizó seguimiento digital der-matoscópico con mapeo corporal. Se detectaron cambios en nevos melanocíticos preexistentes, aparición segundos melanomas y metástasis cutáneas.El grupo de pacientes con antecedentes de melanoma y en tratamiento con BRAFi o combinación de BRA-Fi y MEKi se beneficia especialmente del control der-matológico con seguimiento digital dermatoscópico y mapeo corporal.


Vemurafenib is an inhibitor of the serine / threonine kinase BRAF enzyme currently used in the treatment of patients with locoregional spread and metastatic melanoma carriers of the mutationV600E of the BRAF gene. It has been associated with multiple cu-taneous adverse effects including changes in melanocytic nevi, appearance of new nevi and even second melanomas. Dermoscopic digital follow-up with total body mapping has proven useful in the early diagnosis of melanoma.We present two cases of patients with a history of me-lanoma in treatment with BRAF inhibitors (BRAFi) and inhibitors of BRAF and MEK (MEKi) in whom a digital dermoscopic follow-up was performed with body mapping. Changes in preexisting melanocytic nevi, second melanomas and cutaneous metastases were detected.The group of patients with a history of melanoma and in treatment with BRAFi or a combination of BRAFi and MEKi especially benefits from dermato-logical surveillance with digital dermoscopic follow-up and total body mapping.

ABSTRACT

Abstract: Diphencyprone has been reported as a local immunotherapy for cutaneous melanoma metastases. We aim to report cases of melanoma patients treated with diphencyprone in a single Brazilian institution and highlight their outcomes. Since 2012, we have treated 16 melanoma patients with cutaneous metastases with topical diphencyprone. To date, we have had 37.5% of complete response, 25% of partial responses, and 31.25% patients without any response. Treatment was well tolerated and local toxicity was easily controlled. We believe topical diphencyprone is a feasible treatment that can be another option for treating melanoma patients, especially in cases of in-transit or extensive disease.

ABSTRACT

Los hemangiomas de la infancia (HI) son tumo-res vasculares que presentan un patrón evolutivo característico. Existe un subgrupo de HI que pre-senta un tipo de crecimiento distinto denominados hemangiomas de la infancia con crecimiento míni-mo o detenido (HI-CMD). En estos, el componen-te proliferativo no supera el 25% de la superficie total; además, afecta a niños de al menos dos meses de edad en la consulta inicial o a niños menores de dicha edad en los que se realiza un seguimiento mayor a 2 meses. Los HI- CMD con lipoatrofia son una variante poco frecuente de HI de la cual exis-ten escasos reportes en la literatura. El objetivo de nuestro trabajo es presentar un caso de HI-CMD con lipoatrofia en una lactante. Los HI-CMD presentan un desafío diagnóstico ya que deben ser reconocidos precozmente y diferencia-dos de otras lesiones vasculares.


Infantile hemangiomas (IH) are vascular tumors that present a characteristic evolutive pattern. There is a subgroup of hemangiomas that pre-sents a different type of growth called infantile hemangiomas with minimal or arrested growth (IH-MAG). In these, the proliferative component does not exceed 25% of the total surface; it also affects children of at least two months of age in the initial consultation or children under that age in which a follow-up of more than 2 months is carried out. IH-MAG with lipoatrophy is a rare variant of IH of which there are few reports in the literature.The aim of our report is to present a case of IH-MAG with lipoatrophy in an infant. IH-MAGs present a diagnostic challenge since they must be recognized early, and differentiated from other vascular lesions.

ABSTRACT

Abstract: Cutaneous lymphomas are classified according to their cellular origin into T-cell lymphoma and B-cell lymphoma. The annual incidence rate is 0.3 per 100,000 population. We report a case of a 56-year-old male patient who presented with a two-month history of nodules of varying sizes, some ulcerated, on the face, abdomen, and upper limbs. Histopathological examination and immunohistochemical study confirmed the diagnosis of primary cutaneous centrofollicular lymphoma. Studies have shown an increased incidence of non-Hodgkin lymphomas in the last decade. We report an infrequent case that should be kept as a differential diagnosis of patients with nodules and cutaneous papules.
