ABSTRACT
Abstract Background Mohs micrographic surgery is an established technique in the treatment of cutaneous neoplasms. It offers higher cure rates and the main indications are non-melanoma malignant skin tumors. Few studies have been performed on the treatment of rare tumors through this technique. Objective To study rare skin tumors and rare variants of basal cell carcinoma and squamous cell carcinoma submitted to Mohs micrographic surgery in a tertiary service in relation to frequency, disease-free evolution, and applicability of this surgical procedure for this group of tumors. Methods This was a retrospective observational study including rare skin tumors and less common variants of basal cell carcinoma and squamous cell carcinoma treated using Mohs micrographic surgery, between October 2008 and April 2021. Results During the study period, 437 tumors were treated using Mohs micrographic surgery, and 22 (5%) rare skin tumors were selected. The tumors comprised three dermatofibrosarcomas protuberans, two atypical fibroxanthomas, two spiradenomas, two hypercellular fibrohistiocytomas, one primary cutaneous adenocarcinoma, one trichoblastoma, one porocarcinoma, one chondroid syringoma, one cutaneous angiosarcoma, one Merkel cell carcinoma, and one sebaceous carcinoma. Six other cases of rare basal cell carcinoma variants with trichoepitheliomatous differentiation, metatypical basal cell carcinoma, and clear cell squamous cell carcinoma were included. There were no cases of recurrence after an average of six years of follow-up. Study limitations This is a retrospective study on rare neoplasms carried out in a single referral center, and this surgical technique isn't widely available in the public service. Conclusion This retrospective case series showed that Mohs micrographic surgery is an appropriate treatment for rare skin tumors. They corresponded to 5% of the tumors treated by the technique during a 12-year-period, with no recurrences identified.
ABSTRACT
Os linfomas B primários cutâneos (LBPCs) são linfomas não Hodgkin, de acometimento exclusivamente cutâneo, e representam 25% dos linfomas primários cutâneos. São divididos, conforme comportamento clínico, em indolentes e intermediários. O tratamento das formas indolentes inclui a cirurgia, a radioterapia e, em casos extensos, o rituximabe. Relata-se o caso de mulher de 57 anos, com placa única no braço esquerdo, com diagnóstico de LBPC da zona marginal, tratado com excisão com margens de segurança de 5mm, sem recidiva após 36 meses de seguimento. A cirurgia é uma alternativa terapêutica com bom resultado clínico, sem impacto na sobrevida livre da doença.
Primary cutaneous B-cell lymphomas are non-Hodgkin lymphomas presenting only in the skin and represent 25% of all primary cutaneous lymphomas. Based on their clinical behavior, they are classified into indolent and intermediate forms. Treatment of indolent forms includes surgery, radiotherapy, and, in extensive disease, rituximab. We report a case of a 57-year-old woman with a single nodule in the left arm treated with surgical excision with 5-mm security margins, without relapse after 36 months. Surgery is a therapeutic option in these lymphomas without compromising disease-free survival.
ABSTRACT
Rinofima é uma doença desfigurante e progressiva do nariz, com alta prevalência. Apesar de ser considerada benigna, muitos pacientes têm procurado tratamentos curativos devido a deformidade estética e estigmatização social. Existem diversas técnicas cirúrgicas descritas para o tratamento desta doença. O objetivo deste relato é apresentar um caso que necessitou de abordagem terapêutica pouco utilizada para tratamento de rinofima devido às múltiplas comorbidades do paciente. O procedimento foi realizado sem complicações no intra e pós-operatório, e o paciente mantém seguimento ambulatorial com bom resultado estético final a longo prazo
Rhinophyma is a disfiguring and progressive disease of the nose with high prevalence. Despite being considered a benign condition, many patients have sought curative treatments due to aesthetic deformity and social stigmatization. There are several surgical techniques described in the treatment of this disease. This report aims to present a case that required an unusual therapeutic approach for the treatment of rhinophyma, given the patient's multiple comorbidities. The procedure was performed with no complications in the intra and postoperative period. The patient maintains an outpatient follow-up with a good long-term aesthetic result
ABSTRACT
O tratamento isolado do queloide apresenta resultado variável e, muitas vezes, insatisfatório. A combinação de terapêuticas tem se mostrado uma alternativa eficaz, principalmente para os casos recalcitrantes. A excisão cirúrgica e a irradiação no pós-operatório imediato com feixe de elétrons é uma alternativa efetiva na cicatrização e redução da taxa de recidiva dessas lesões. Os autores descrevem um paciente que apresentava queloide volumoso recalcitrante que obteve bom resultado terapêutico.
Isolated keloid treatment has variable and often unsatisfactory results. The combination of therapies has proven to be an effective alternative mainly for recalcitrant cases. Surgical excision and immediate postoperative electron beam irradiation is an effective alternative in healing and reducing the recurrence rate of these lesions. The authors describe a patient with recalcitrant bulky keloid who had a good therapeutic outcome.
ABSTRACT
Several studies show that the risk of accidents involving patients with epilepsy is much higher compared to the general population. The objective of this study was to identify the frequency and type of seizure related injuries in children diagnosed with epilepsy. In addition we also assessed possible risk factors associated with this seizure related accidents in childhood. This study was conducted at the pediatric epilepsy clinic of Unicamp, from January 2005 to August 2006. We evaluated 100 consecutive children with epilepsy. Parents were interviewed by one of the authors using a structured questionnaire that included questions about seizure related accidents and related injuries. Forty-four patients reported seizure related accidents. Eighteen patients needed medical assistance at an emergency room due the severity of their seizure related accident. Forty patients reported having a seizure related accident prevented by a bystander. Another 14 patients reported avoiding a seizure related accident by luck alone. Contusions and lacerations were the most common type of lesion associated with seizures. Patients with symptomatic/probable symptomatic epilepsy and those using higher numbers of anti-epileptic drugs (AEDs) were at greater risk for seizure related accidents (p<0.05). We conclude that patients with symptomatic/probable symptomatic epilepsy and on multiple AEDs are at increased risk of seizure related accidents. Parents and caretakers should be even more cautious about risk of injury in such patients.
Vários estudos mostram que o risco de acidentes envolvendo pacientes com epilepsia é muito maior do que na população geral. O objetivo desse estudo foi identificar a freqüência e tipo de acidentes relacionados a crises epilépticas em crianças com diagnóstico de epilepsia. Além disso, também avaliamos os fatores de risco associados às crises epilépticas na infância. Esse estudo foi realizado em nosso ambulatorio de epilepsia infantil da Unicamp, no período de janeiro de 2005 a agosto de 2006. Avaliamos 100 pacientes consecutivos. Os pacientes foram entrevistados por um dos autores, utilizando-se um questionário sobre acidentes e lesões associadas às crises epilépticas. Quarenta e quatro pacientes apresentaram acidentes relacionados às crises epilépticas. Dezoito pacientes precisaram assistencia médica em pronto socorro devido à gravidade das lesões. Quarenta pacientes relataram que um acidente foi evitado devido ao socorro de uma outra pessoa. Outros 14 pacientes relataram que um acidente foi evitado apenas por sorte. Contusões e lacerações foram os tipos de lesão mais comuns. Pacientes com epilepsia sintomática ou provavelmente sintomática, e pacientes em uso de politerapia apresentaram maior risco de acidentes relacionados às crises epilepticas (p<0.05). Concluímos que pacientes com epilepsia sintomática/provavelmente sintomática em uso de politerapia apresentam risco de acidentes elevado. Familiares e cuidadores desses pacientes devem ser ainda mais cautelosos sobre o risco de lesão associada às crises epilépticas.
