ABSTRACT
Introducción: El cáncer vesical es el noveno cáncer más común a nivel mundial. La finalidad de la RTUv en los tumores Ta y T1 es hacer un diagnóstico completo y correcto, y una resección terapéutica. Objetivo: Determinar el porcentaje de muestras con tejido muscular de las RTUv. Materiales y métodos: Estudio retrospectivo, longitudinal y descriptivo. Incluidos todos los informes del Servicio de Anatomía Patológica del HPSB desde el 2001 hasta Julio de 2012, informados como muestra de vejiga o cáncer vesical. Resultados: 122 casos cumplieron todos los criterios. 87.7 por ciento presentaban tejido muscular. De las muestras con diagnóstico de cáncer, 28.6 por ciento presentaban in¬ ltración, 32.4 por ciento eran de alto grado y 67.6 por ciento de bajo grado. Conclusión: cerca del 88 por ciento de las RTUv que se han realizado en los últimos 10 años en nuestra unidad y que están indicadas por el diagnóstico o sospecha de cáncer vesical, tienen tejido muscular y por lo tanto están correctamente realizadas.
Introduction: Bladder cancer is the ninth most common cancer worldwide. The purpose of TURB in Ta and T1 stage tumors is to make a complete and accurate diagnosis, and therapeutic resection. Objective: To determine the percentage of samples with muscle tissue of TURB. Materials and Methods: Retrospective, longitudinal and descriptive study. Including all Service reports HPSB Pathology from 2001 until July 2012, reported as a bladder sample or bladder cancer. Results: 122 cases met all the criteria. 87.7 percent had muscle tissue. Of the samples with cancer diagnosis, 28.6 percent had infiltration, 32.4 percent were high grade and 67.6 percent low grade. Conclusion: About 88 percent of the TURB that have been made in the last 10 years in our unit and are indicated by the diagnosis or suspected bladder cancer have muscle tissue and therefore were made correctly.

Post transplant lymphoproliferative disorder (PTLD) is the commonest form of post transplant malignancy in children. The incidence in renal transplant recipients varies between 2 percent-4 percent. They are characterized by uncontrolled B lymphocyte proliferation, in most cases driven by Epstein Barr virus (EBV). They are more common in younger children, EBV seronegative patients and those who receive aggressive immunosuppression. PTLD commonly presents in an unspecific form and it requires high suspicion rate for its diagnosis, especially in children with risk factors. We report a twelve year-old girl who developed fever, sore throat and lymph node enlargement, six months after receiving a renal allograft. Laboratory assessment and imaging studies were compatible with PTLD, which was confirmed by biopsy. Treatment was reduction of immunosuppression and surveillance. The patient had a favorable evolution.
