ABSTRACT
Propósito: el signo de Leser-Trélat conjuga la presencia simultánea de queratosis seborreica eruptiva con una neoplasia maligna, pero existen publicaciones de pacientes con queratosis con o sin la neoplasia. Se buscó establecer si hay evidencia sobre esta asociación para considerar la potencialidad de la aparición de tales lesiones dermatológicas como un hallazgo precoz de neoplasias malignas. Fuente de datos: revisión sistemática de la literatura ubicada en Medline, Cochrane, Lilacs, Scholar Gloogle e Imbiomed. Selección de estudios: se evaluaron todos los artículos afines a queratosis seborreica eruptiva y cáncer, sin límite en edad, sexo, tipo de artículo o idioma. Extracción de datos: se leyeron de 668 resúmenes y se revisaron 120 artículos completos, 66 utilizados en este informe. Resultados: la evidencia que apoya la asociación entre queratosis seborreica súbita y cáncer es pobre: sólo existen cuatro estudios de casos y controles cuyos resultados no apoyan esta asociación. Conclusiones: la gran mayoría de las publicaciones son producto del hallazgo al azar de las dos entidades y no producto de la búsqueda sistemática de una de ellas cuando aparece la otra, lo que refleja una especie de sesgo de selección a la hora de publicar dichos casos.
Purpose: the sign of Leser-Trélat conjugates the simultaneous presence of eruptive seborrheic keratoses with a malignancy, but there are reports of patients with keratosis with or without neoplasia. The establishment of whether there is evidence for this association to consider the potential for the occurrence of such skin lesions as an early finding of malignant neoplasms was sought. Data Sources: a systematic review of the literature located on Medline, Cochrane, Lilacs, Schoolar Google and Imbiomed. Study Selection: all articles related to eruptive seborrheic keratosis and cancer, with no limit on age, sex, type of article or language were evaluated. Data Extraction: 668 abstracts were read and 120 full articles were reviewed, 66 used in this report. Results: the evidence supporting the association between sudden seborrheic keratosis and cancer is poor: there are only four case-control studies whose results do not support this association. Conclusions: the vast majority of publications are the product of chance finding of the two entities and not the result of a systematic search of one of them when the other appears, reflecting a kind of selection bias in publishing such cases.

Objetivo: relatar um caso de tumor estromal gastrointestinal (GIST) de intestino delgado em um paciente residente no município de Mocajuba-PA, ano de 2012. Método: as informações foram obtidas através de revisão do prontuário, en-trevista com o paciente, registro fotográfico dos métodos diagnósticos e procedimentos cirúrgicos, aos quais o paciente foi submetido e revisão da literatura. Considerações Finais: o caso relatado contraposto com a literatura acerca da doença em questão, mostra a escassez de sintomas de um paciente com GIST e a necessidade de tratamento precoce.
Objective: report a case of gastrointestinal stromal tumor of small bowel of a lender in the city of Mocajuba-PA in2012. Methodology: the necessary data was obtained by medical chart review, interview with the patient, photographicregister of the image diagnose exams and surgical procedures that were performed and literature review. Final con-siderations: this case opposed to the literature on the disease in question shows a lack of symptoms of a patient withGIST and the need for early treatment.
ABSTRACT
Cuando tenemos un tumor óseo maligno del fémur distal con contaminación de la articulación, ya sea por extensión del tumor, fracturas secundarias al tumor con trazo intraarticular o contaminación en una biopsia tomada de manera inadecuada, debemos realizar resecciones extraarticulares de rodilla para lograr un control primario del tumor. Podemos emplear varias técnicas para lograr este fin, y una buena reconstrucción; la técnica que empleamos es la resección extraarticular más la preservación del mecanismo extensor, poco conocida en nuestro medio y de la cual es pionera el instituto Nacional de Cancerología. Con ella, hemos logrado un adecuado control tumoral primario de las lesiones óseas malignas en el fémur distal, menor número de complicaciones, una rápida rehabilitación y retorno a sus actividades habituales. Por esto, el interés de dar a conocer dicha técnica en los grupos de ortopedia oncológica, para que haga parte de su armamentario quirúrgico habitual.
When we encounter a malignant bone tumor in the distal femur with contamination of the joint, whether caused by tumor extension, secondary tumor fractures with intra-articular traces, or by contamination produced by inadequate taking of biopsies, extra-articular knee resection must be performed in order to achieve primary tumor control. Several methods are at our disposal to do so; our reconstruction technique of choice is that of extra-articular resection plus preservation of the extensor mechanism. this method is not well known locally; however, the National Cancer institute of Colombia has pioneered its use, thus allowing us to attain adequate primary tumor control in malignant bone lesions in the distal femur, with fewer complications, rapid rehabilitation and more immediate return to daily activities. We are, therefore, interested in sharing our expertise on this method with orthopedic oncologists so that they may include it their armory of standard surgical procedures.

Los tumores estromales gastrointestinales son poco comunes. Representan neoplasias de células intersticiales de Cajal; especialmente, por mutaciones del receptor CD117 (c-Kit), cuya detección inmunohistoquímica confirma el diagnóstico, y para el cual existen inhibidores específicos (imatinib, sunitinib). Se describen las características clínicas, el diagnóstico, el tratamiento y el seguimiento de 6 casos (1 esofágico, 2 gástricos, 1 duodenal, 1 yeyunal y 1 colónico), de los cuales 4 son mujeres, y donde las edades oscilaron entre los 38 y los 78 años (promedio: 52). según cada caso, se evidencian manifestaciones (síndrome anémico, dolor y masa abdominal, etc.), las características operativas de los estudios imagenológicos y endoscópicos, y la histopatología. Hubo resección mínimamente invasiva en 2 pacientes, 1 sincronía con adenocarcinoma colorrectal y 2 casos de recurrencia. Los hallazgos son acordes con la literatura. Existen controversias respecto al pronóstico y la experiencia médica es limitada, por la escasa frecuencia, dado lo cual son necesarias las evidencias en torno a esta enfermedad. © 2012 Instituto Nacional de Cancerología. publicado por elsevier españa, S.L. todos los derechos reservados.
Gastrointestinal stromal tumors (GIST ) are uncommon. They are neoplasms of interstitial cells of Cajal, mainly due to receptor mutations CD117 (c-Kit), with their diagnosis being confirmed by immunohistochemical methods, and for which there are specific inhibitors (imatinib, sunitinib). We describe the clinical features, diagnosis, treatment, and follow-up of 6 cases (1 esophageal, two gastric, one duodenal, one jejunal and one colon), of which 4 were women, with an age range between 38 and 78 years (mean: 52). The signs and symptoms of each case are presented (anemic syndrome, abdominal pain and mass, etc.), as well as the operating characteristics of the imaging and endoscopic tests, and the histopathology. Minimally invasive resection was performed in 2 patients, 1 synchronous with colorectal adenocarcinoma and 2 cases of recurrence. The findings are consistent with the literature. There are controversies in prognosis, and medical expertise is limited by the low frequency, therefore, more evidence is needed about this disease.

Report of a rare case of an 83-year-old patient with lymphoma of the terminal ileum causing obstructive/perforated acute abdomen synchronous with sigmoid colon adenocarcinoma and review of literature data about small bowel malignancies, particularly lymphomas. It seems to correspond to a rare disease (2% of all bowel cancers), more prevalent in elderly and immunocompromised patients, whose symptoms are vague and early diagnosis is difficult, often making it impossible to establish the correct therapy. (AU)
Relato de caso raro de um paciente de 83 anos, com linfoma de íleo terminal causador de abdome agudo obstrutivo/perfurativo sincrônico à adenocarcinoma de cólon sigmoide e revisão dos dados disponíveis na literatura acerca das neoplasias de intestino delgado, em especial os linfomas. Constata-se que corresponde a uma afecção rara (2% de todas as neoplasias intestinais), mais predominante em pacientes idosos e imunodeprimidos, cuja sintomatologia é vaga e o diagnóstico precoce difícil, fato que impossibilita muitas vezes a instituição da terapêutica correta.

INTRODUÇÃO: O tumor estromal gastrointestinal (GIST) é neoplasia pouco freqüente, sendo rara a combinação de acometimento duodenal e hemorragia digestiva, por isso apresenta-se este relato. RELATO DO CASO: Homem de 64 anos admitido com quadro de dor abdominal, melena e tumoração palpável em epigástrio e hipocôndrio esquerdo, sendo notado um tumor de paredes espessadas e conteúdo cístico na tomografia computadorizada de abdome, em topografia de cauda pancreática. Encontrado na laparotomia de urgência tumor em quarta porção duodenal com invasão de cólon em ângulo esplênico, sendo realizada ressecção em bloco do duodeno acometido, segmento de cólon transverso e descendente, com boa evolução pós-operatória. Diagnosticado por imunoistoquímica GIST de duodeno com invasão de parede colônica, sendo o tratamento complementado com mesilato de imatinib. CONCLUSÃO: A hemorragia digestiva é uma das possíveis complicações do GIST. Apenas o tratamento cirúrgico precoce é capaz de prevenir as graves complicações do choque hemorrágico.
BACKGROUND: Gastrointestinal stromal tumor (GIST) represents an uncommon form of neoplasm. The combination of duodenal GIST and gastrointestinal bleeding consist of a rare presentation for such tumors. AIM: To report duodenal GIST case complicated by gastrointestinal bleeding. CASE REPORT: A 64-year-old male was admitted presenting abdominal pain, melena and a palpable mass in epigastrium and left upper abdomem regions. CT scan reveled a thick wall tumor containing cystic content in the pancreatic tail topography. At emergency laparotomy, a tumor in the fourth portion of the duodenum presenting colonic invasion in splenic flexure was found. En-bloc resection of the tumor was carried out, included the fourth portion of the duodenum and the transverse and descending colon, without postoperative complications. Immunohistochemical staining of the resected specimen confirmed the diagnosis of duodenal GIST with colon wall invasion. CONCLUSION: Gastrointestinal hemorrhage is one of the possible complications of GIST. Early surgical treatment is the only effective therapeutic option to avoid severe complications of hemorrhagic shock.
