We describe the use of modified Tripier flap for reconstruction of a surgical defect in the lower eyelid region, after excision of nodular basal cell carcinoma.
We report the case of an 11-year-old male patient with a histopathological and immunohistochemical diagnosis of dermatofibroma with an atypical clinical presentation on the right forearm. Although dermatofibroma is considered a benign skin tumor, some of its differential diagnoses, such as dermatofibrosarcoma protuberans and malignant fibrous histiocytoma, are truly aggressive. Lesions with atypical clinical aspects and topology associated with specific histopathological variants are some of the criteria for complete tumor excision.
Knowledge of the inverted "T" incision - used in plastic, oncologic and orthopedic surgery - has allowed its adaptation for the diagnostic assessment and therapeutical approach of acral, nodular lesions. The authors describe the use of this technique for the surgical approach of a patient with a plantar nodular lesion, further diagnosed as a calcified angioleiomyoma.
Reconstruction of surgical defects in the pubic region is a challenge to any surgeon. Our goal was to demonstrate the use of the bilobed flap to reconstruct the pubic region skin after the excision of a recurrent HPV lesion, resistant to conventional treatments. In spite of its classical use in nasal reconstructions, the bilobed flap has applications in extranasal defects, with excellent functional and aesthetic results.
Resumo: O pinçamento do leito ungueal gerado pela hipercurvatura transversa da unha é chamado de unha em pinça e pode provocar dor e constituir problema estético. A unha em pinça pode apresentar três tipos clínicos, mais comuns, sendo a unha em telha um deles. As causas podem ser hereditárias ou adquiridas. Os dedos dos pés são acometidos com maior freqüência. Os tratamentos conservadores são os preferidos pelos pacientes, porém, os tratamentos cirúrgicos produzem os melhores resultados. Das técnicas cirúrgicas, a técnica de Zook é opção diferente, pois, preserva a matriz e o tamanho da unha. Os autores apresentam cinco pacientes com unha em telha, tratados com a técnica de Zook. Palavras-chave: Doenças da unha; Unhas encravadas; Unhas malformadas Abstract: The pinching of the distal nail bed, caused by transverse overcurvature of the nail is called pincer nail. It frequently causes pain and aesthetic problems. Pincer nail may present in three fre
Dear Editor, Frey's syndrome (FS) is characterized by sweating and erythema in the parotid gland region, related to salivary stimulus, and emerges after parotid gland traumas, such as parotidectomy, the drainage of abscesses, gunshot wounds, and shingles. 1 We present a case of a 60-year-old, white, female patient, who underwent a partial left parotidectomy 10 years ago due to a benign tumor, and who, some months after the procedure, began to suffer from sweating and erythema in the mandibular angle, pre-auricular and retro-auricular ipsilateral regions. In spite of the discomfort during meals, she never sought out treatment. As the hypothesis of FS was put forth, the Minor test was performed by applying a 2% iodine tincture in the region indicated by the patient, During follow-up, the patient presented no clinical complaints up to one year after the treatment, at which time she was submitted to the reapplication of botulinum toxin type A, but in a smaller quantity (34 U) in order to attain a more satisfactory response.
O conteúdo do saco herniário sempre foi motivo de preocupação por parte do cirurgião, embora a estrutura de sua parede seja ainda pouco estudada e conhecida. O objetivo do trabalho é avaliar a influência de sexo, cor, idade, região do saco herniário, lado da hérnia, largura, comprimento e espessura da amostra peritoneal na presença de fibras musculares lisas (FML) na parede do saco herniário inguinal. Pretende-se também descrever a histologia dos sacos herniários e apresentar algumas teorias sobre a origem das FML, além de destacar a importância do conhecimento da estrutura sacular na identificação de condições patológicas encobertas e certificar o uso do próprio saco como instrumento de reforço nas correções cirúrgicas. Amostras de 252 sacos herniários obtidos no tratamento operatório de hérnias inguinais indiretas, diretas, recidivadas e encarceradas foram encaminhadas para o estudo histopatológico, e foram coradas por Hematoxilina-Eosina (HE) e tricrômico de Gomori para a identificação de FML. Estas estiveram presentes em 67,9% das amostras, e ocorreram de modo significativo nas hérnias indiretas e recidivadas, quando comparadas com as diretas e encarceradas. Em relação às variáveis estudadas, os pacientes que apresentaram FML não diferiram significativamente daqueles em que as mesmas não foram observadas. Quando presentes, as FML muitas vezes estavam associadas com vasos sangüíneos espessos, sugerindo a origem à partir da camada média do vaso e podem representar um reforço tecidual em resposta ao trauma mecânico ou a outros fatores da patogênese da hérnia. Foi observado também que o saco herniário pode sediar vários processos patológicos que atingem o peritônio parietal, como a endometriose, inflamações específicas e processos hiperplásicos ou mesmo neoplásicos, inclusive podendo constituir, em alguns casos, a primeira evidência de neoplasias.
The hernial sac contents was always motive of concern by part of the surgeons, although still be little studied and known the structure of its wall. The purpose of this work was to evaluate the influences on the inguinal hernial sac of sex, color, age, region of hernial sac, hernia side, width, length, thickness in the presence of smooth muscle fibers (SMF). Also, it is intended to describe the structure of the hernial sacs studied and to present some theories on the SMF source, besides to emphasize the possible significance of knowledge on sacs structure to the hiden pathological condition, identification and the use of the sac itself as a reinforcement instrument on surgical corrections. Samples of 252 hernial sacs obtained during operative therapy of indirects, directs, relapsings, incarcerated inguinal hernias were sent to histopathological study when the samples were stained by Hematoxilin-Eosin (HE) and Gomori trichrome for SMF identification. These were present in 67,9% of the samples and they occurred significantly on indirects and relapsings when were compared to the directs and encarcerateds. With reference to the studied variables, the patients who present...
