ABSTRACT

Introdução: A região anterior do tórax constitui área fotoexposta que apresenta efeitos do fotodano. O microagulhamento é opção segura para rejuvenescimento dessa área, promovendo também a melhora de discromias. Objetivo: Avaliar a resposta histológica cutânea após três sessões mensais de microagulhamento para tratamento de discromias da região anterior do tórax. Métodos: Foram realizadas, três sessões mensais de microagulhamento com agulhas de 1,5mm de comprimento, e também biópsias cutâneas antes e 90 dias após o início do estudo. As amostras histológicas foram avaliadas com as colorações de HE e Fontana-Masson. O conteúdo de melanina foi mensurado com base em clusters dérmicos. Resultados: Seis pacientes com idades entre 38 e 67 anos, fototipos II-III, escala Glogau II-IV foram incluídos. Uma correlação positiva foi observada entre o tempo e o conteúdo dérmico de melanina (p= 0,029): três sessões de microagulhamento reduziram esse conteúdo no D90 em comparação com o tempo inicial (6.4 ± 1.7 MC em D0 versus 3.1 ± 0.4 em D90, p = 0.05). Três pacientes relataram melhora global da pele no D90. Conclusões: O mecanismo proposto do microagulhamento para promover clareamento inclui proliferação de fibroblastos e neocolagênese na derme superior. Esse é o primeiro estudo a avaliar histologicamente os achados associados ao clareamento da região do tórax decorrente do microagulhamento.


Introduction: The chest is a photoexposed area that shows effects of photodamage. Microneedling is a safe option for the rejuvenation of this area, also leading to improvement in dyschromias. Objective: To evaluate histologic cutaneous response after three monthly sessions of microneedling for the treatment of dyschromias on the chest. Methods: Three monthly sessions of microneedling, with 1.5mm length needles were performed, as well as skin biopsies before and 90 days after commencement of the study. Histologic samples were evaluated with H&E and Fontana-Masson stains. Melanin content was measured based on dermal clusters. Results: Six patients between 38 and 67 years of age, phototypes II-III, Glogau scale II-IV were included. A positive correlation was observed between the time and dermal content of melanin (p= 0.029): three sessions of microneedling reduced this content on D90 compared to the beginning (6.4 ± 1.7 MC on D0 versus 3.1 ± 0.4 on D90, p = 0.05). Three patients reported global skin improvement on D90. Conclusions: The proposed mechanism of microneedling to promote lightening includes fibroblast proliferation and neocollagenesis in the upper dermis. This is the first study to evaluate the histology of the findings associated to lightening of the chest due to microneedling.

ABSTRACT

Queloides apresentam impacto funcional, estético e psicológico podendo influenciar a qualidade de vida desses pacientes. Além disso, diante da alta taxa de recorrência, particularmente em lesões de grandes dimensões e localizadas na face anterior do tórax, são mais difíceis de tratar. Este artigo relata tratamento de sucesso para queloide na face anterior do tórax utilizando nova técnica que combina luz intensa pulsada, toxina botulínica tipo A e tratamento convencional com infiltração de corticosteroide.


Keloids have functional, aesthetic and psychological impacts that can influence the patients' quality of life. Moreover, given the high rate of recurrence ­ particularly in large lesions located in the anterior thoracic region ­ they are more difficult to treat. This paper reports a successful treatment for keloids in this area using a new technique that combines intense pulsed light, botulinum toxin type A and the conventional treatment with injection of corticosteroids.

ABSTRACT

Abstract

Glomus tumors originate from modified perivascular muscle cells. The most common form is the solitary one. The multiple form may be associated with dominant genetic inheritance. We report a case of a patient with hemangiomatous lesions on the calcaneus and wrist since birth. In 6 years, there was progression of lesions throughout the body. Multiple glomangiomas are asymptomatic and more common in childhood. They can be confused with other vascular malformations. Histopathological diagnosis is essential. The case shows a type 2 segmental manifestation that can be explained by genetic mutation leading to the loss of heterozygosity. As the child grows, the lesions may disseminate due to mutation in distant parts of the skin. Literature shows few reports. The treatment is conservative.

ABSTRACT

Introdução: Manchas vinho do Porto (MVP) são malformações vasculares presentes ao nascimento que podem causar alterações emocionais no paciente conforme sua localização. Tratamentos com luz intensa pulsada (LIP) e outros tipos de lasers têm sido relatados com respostas variadas. Objetivos: Revisão da literatura sobre opções terapêuticas utilizando fontes de luz nas MVP e demonstração de tratamento bem-sucedido com LIP associada a laser Nd:YAG. Método: Paciente feminina, de 14 anos, apresentando MVP na região supralabial foi tratada com a associação de laser Nd:YAG 1064nm e LIP 560nm. Foram realizadas 8 sessões com, em média, 30 dias de intervalo entre elas. Estudo realizado na Clínica Dermatológica Célia Kalil. Resultado: A paciente obteve total desaparecimento da MVP na área tratada, com o mínimo de efeitos adversos. Conclusão: A associação de LIP 560nm e laser Nd:YAG 1064nm parece ser uma alternativa adequada no tratamento das MVP.


Introduction: Port wine stains (PWS) are vascular malformations present at birth, and, depending on their location, they can cause emotional changes in the patient. Studies on the treatment of PWS with intense pulsed light (IPL) and other types of lasers presented different responses. Objectives: The objective of this study was to review the literature on the treatment options of PWS with light sources, demonstrating the success of IPL associated with Nd:YAG laser. Method: A 14 years old female patient with PWS in the supralabial region was treated with the association of 1064- nm Nd:YAG laser and 560-nm IPL. She underwent eight treatment sessions with a mean interval of 30 days between each session. The study was conducted at the Célia Kalil Dermatology Clinic. Result: The port wine stains disappeared completely with a very low incidence of adverse events. Conclusion: The association of 560-nm IPL and 1064-nm Nd:YAG laser seemed an adequate treatment alternative for PWS.
