Carcinoma de células renales con invasión vascular: mortalidad y factores pronósticos / Renal cell carcinoma with vascular invasion: mortality and prognostic factors

Objetivo. Análisis de los resultados obtenidos en el seguimiento de los pacientes intervenidos de carcinoma renal con invasión vascular en nuestro centro, evaluación de los factores pronósticos y de las complicaciones. Material y métodos. Estudio observacional retrospectivo de 37 pacientes diagnosticados de carcinoma renal con invasión vascular intervenidos entre mayo de 1999 y julio de 2013. Se emplean el método de Kaplan-Meier para el análisis de supervivencias y la prueba de Mantel-Haenszel (LogRank) y el modelo de riesgos proporcionales de Cox para el análisis de los factores de riesgo de mortalidad. Resultados. La mediana de edad fue de 60 años. El tiempo de seguimiento medio de 42,1 meses. Las medianas de supervivencia global y supervivencia libre de enfermedad fueron de 53,8 y 36,3 meses respectivamente. Existe asociación estadística entre supervivencia global y el ASA (p=0,047), estadio tumoral (p=0,003), la afectación ganglionar (p=0,024), la presencia de metástasis (p=0,013), el nivel de trombo tumoral (p=0,05) y el tipo histológico (p=0,001). Catorce pacientes presentaron complicaciones grado IIIb o mayor según la clasificación de Clavien-Dindo, siendo la más frecuente el sangrado. Conclusiones. El carcinoma renal con invasión vascular es una enfermedad con alta tasa de mortalidad. La cirugía es una opción terapéutica que puede resultar curativa. El número de complicaciones es importante. La supervivencia está condicionada por el ASA, el estadio tumoral, el nivel de trombo tumoral, la afectación ganglionar, las metástasis y el tipo histológico (AU)

Objective. Analysis of the results of patients who had been operated of renal cell carcinoma with vascular invasion in our institution, evaluation of prognostic factors and complications. Methods. Retrospective observational study of 37 patients diagnosed of renal cell carcinoma with vascular invasion operated between May 1999 and July 2013. We used the method of Kaplan-Meier survival analysis and the Mantel-Haenszel's test (log rank) and the Cox's proportional hazards analysis test to analyse the risk factors of mortality. Results. The median age was 60 years. Mean follow-up period was 42.1 months. The median overall survival and disease-free survival were 53.8and 36.3 months, respectively. There was statistical association between overall survival and ASA (p=0.047), tumor stage (p=0.003), lymph node involvement (p=0.024), presence of metastases (p=0.013), level of tumor thrombus (p=0, 05) and histological type (p=0.001). 14 patients had grade IIIb complications or higher according to the Clavien Dindo classification, the most frequent was bleeding. Conclusions. Renal cell carcinoma with vascular invasion is a disease with high rate of mortality. Surgery is a therapeutic option that can be curative. The number of complications is important. Survival is conditioned by the ASA, tumor stage, the level of tumor thrombus, lymph node involvement, metastasis and histological type (AU)

Peliosis hepatis due to disseminated tuberculosis in a patient with AIDS.

Peliosis hepatis is a rare histopathological entity of unknown etiology. We present a case of peliosis hepatis in a 44-year-old man with disseminated tuberculosis and acquired immunodeficiency syndrome. The diagnosis of peliosis hepatis was based on liver biopsy results which were suggestive of tuberculous etiology. Diagnosis of tuberculosis was confirmed by auramine stain, rRNA amplification and culture of Mycobacterium tuberculosis from synovial fluid of the elbow joint. The patient responded favourably to tuberculostatic treatment with four drugs and the early initiation of highly active antiretroviral therapy. Histopathological evidence of peliosis hepatis, without an obvious cause, makes it necessary to rule out tuberculosis, especially in the context of immunodeficiency diseases and immigrants from endemic areas.

Neurotekeoma celular de la conjuntiva bulbar. Caso clínico / Cellular neurothekeoma of the bulbar conjuctiva. Case report

Caso clínico: El neurotekeoma celular es un subtipo de neurotekeoma de histopatogenia confusa. Presentamos un raro caso de neurotekeoma celular de la conjuntiva bulbar en una mujer de 23 años.Discusión: El neurotekeoma o mixoma de la vaina nerviosa es un raro tumor benigno que surge en la infancia o en el inicio de la edad adulta, afectando sobre todo la parte superior del cuerpo (cabeza, cuello y miembros superiores). En nuestro conocimiento, éste es el primer caso descrito en la literatura de neurotekeoma en esta localización. Dado su aspecto se hace necesaria la biopsia para poder establecer el diagnóstico diferencial con respecto a quistes y neoplasias malignas conjuntivales (AU)
