RESUMO
A neurofibromatose tipo 1 (NF1) é um distúrbio neurocutâneo hereditário no qual se formam tumores no sistema nervoso (neurofibromas). Os neurofibromas são os tumores benignos mais comuns na NF1. O tipo, o tamanho, o número e a localização dos neurofibromas devem ser considerados para a escolha do tratamento. Apresentamos um caso de NF1, no qual foi realizada uma ampla ressecção do couro cabeludo devido à presença de múltiplos neurofibromas. Associado a isso, a reconstrução foi realizada com retalhos de avanço mais autoenxerto de pele parcial, com resultados favoráveis e boa cobertura das áreas onde os tumores foram removidos.
Neurofibromatosis type 1 (NF1) is an inherited neurocutaneous disorder in which tumors form in the nervous system (neurofibromas). Neurofibromas are the most common benign tumors in NF1. The type, size, number, and location of the neurofibromas should be considered for the choice of treatment. We present a case of NF1, in which a wide scalp resection was performed due to the presence of multiple neurofibromas. Associated with this, reconstruction was performed with advancement flaps plus partial skin autograft with favorable results and good coverage of the areas where the tumors were removed.
RESUMO
O tumor filoide é uma neoplasia fibroepitelial rara que representa 0,3 a 1% de todas as neoplasias mamárias. De acordo com a classificação histopatológica, 12 a 26% são do tipo borderline e aproximadamente 15% desses tumores recorrem após excisão cirúrgica. O tratamento recomendado para todos os tipos de tumor filoide é a excisão cirúrgica, e no caso de tumores gigantes o tratamento deve ser multidisciplinar. Apresentamos o caso de uma mulher de 46 anos com tumor filoide na mama esquerda que recorreu 4 anos após a excisão cirúrgica. O estudo anatomopatológico qualificou-o como tumor gigante e o estudo histopatológico relatou tumor filoide borderline. Foi submetida a excisão cirúrgica com mastectomia esquerda e reconstrução mamária com retalho de grande dorsal mais enxerto de gordura. A paciente apresentou evolução favorável sem recidiva. Concluindo, o tumor filoide gigante borderline recorrente é raro e seu manejo cirúrgico representa um desafio tanto na excisão quanto na reconstrução mamária.
Phyllodes tumor is a rare fibroepithelial neoplasm that represents 0.3 to 1% of all breast neoplasms. According to histopathologic classification, 12 to 26% are borderline type and approximately 15% of these tumors recur after surgical excision. The recommended treatment for all types of phyllodes tumor is surgical excision, and in the case of giant tumors the treatment should be multidisciplinary. We present the case of a 46-yearold woman with a phyllodes tumor in the left breast that recurred 4 years after surgical excision. The anatomopathological study qualified it as a giant tumor and the histopathological study reported a borderline phyllodes tumor. She underwent surgical excision with left mastectomy and breast reconstruction by means of a latissimus dorsi flap plus fat graft. The patient presented a favorable evolution without recurrence. In conclusion, the recurrent giant borderline phyllodes tumor is rare and its surgical management represents a challenge both in breast excision and reconstruction.
RESUMO
BACKGROUND: The purpose of this study was to compare 2 techniques used for primary muscular repair and perform a systematic review of the literature to evaluate the effects of radical intravelar veloplasty (IVV) on nonsyndromic unilateral cleft lip and palate. METHODS: This is an ambispective study between 2 groups of patients with unilateral cleft lip and palate who were operated using a radical and conservative form of IVV in Lima Peru. Data collection was accomplished by evaluation of speech development and middle ear function of the patients. A systematic review of the literature for studies published until June 2020 to evaluate the effect using the radical IVV in patients with cleft lip and palate. RESULTS: Our comparative study did not find statistically significant differences in speech development between the studied techniques for unilateral cleft palate repair. Increased number of ear tube placements have been observed in the group treated with radical form of IVV. After systematic literature searching, 10 identified studies were qualified for the final analysis, which included 1367 patients. The overall study quality according to Oxford CEBM and GRADE scale was low. CONCLUSIONS: The results arising from this study provides statistical evidence that one technique let us obtain better speech outcomes. A technique with conservative IVV has statistical significant fewer rate of middle ear disorders after primary cleft palate repair. Based on available scientific evidence, definitive conclusions about the effectiveness of radical IVV on velopharyngeal and middle ear function cannot be drawn.
