TUMOR MIOFIBROBLASTICO DE VEJIGA El tumor miofibroblásticos es un tumor mesenquimal benigno de carácter excepcional, siendo su localización mas habitual es el pulmón; mientras que su aparición en la vejiga, es excepcional, no existiendo mas de 100 casos publicados, de este tipo de tumor en la vejiga. Este tipo de tumor queclínica y radiológicamente, se comporta como un tumor maligno. El diagnóstico patológico es complejo, debido a su similitud con los sarcomas, siendo necesario recurrir a la inmunohistoquímica para un diagnostico de certeza.El tratamiento mediante resección amplia suele ser suficiente no existiendo en la actualidad ningún caso de metástasis a distancia, ni de malignizacion. Presentamos un nuevo caso de este tumor, realizando una amplia revisión bibliográfica.Palabras clave: Pseudotumor inflamatorio. Pseudosarcoma vesical. ABSTRACT MIOFIBROBLASTIC TUMOR OF BLADDERThe miofibroblastic tumor, is a mesenchimal benign tumor of exceptional character, being its localization but habitual it is the lung; while its appearance in the bladder, is exceptional, not existing but of 100 published cases, of this tumor type in the bladder. This tumor type that clinic and radiologics, behave as a wicked tumor. The pathological diagnosis is complex, due to its similarity with the sarcomas, being necessary to appeal to the inmunohistoquimics for a I diagnose of certainty.The treatment by means of wide resection is usually enough not existing any case of metastasis at the present time at distance, neither of malignization. We present a new case of this neoplasm, carrying out a wide bibliographical revision.

The primary bladder amiloidosis is an uncommon pathology, not existing in the world more than 150 published cases, being even more exceptional the secondary bladder amiloidosis being described around 25 cases. The secondary bladder amiloidosis associates in most from the patients to arthritis reumatoide of long evolution. The diagnoses clinical it is difficult, being necessary the differential diagnosis with the bladder tumour. The pathological study and inmunohistochemics, confirm the diagnosis. We present the case of a patient that I debut with frank hematuria, hemodynamic uncertainty and renal inadequacy that it required combined treatment, doctor and surgical for the resolution of their square.

The aim of this article is to report our experience in setting up a laparoscopic radical prostatectomy programme. We believe that knowledge of the difficulties we faced at the start will be useful for those who wish to implement a programme like ours. We hope that by explaining the steps we took as well as our conclusions and recommendations this difficult task can be made easier.

RESUMENHEMATURIA Y FRACASO RENAL AGUDO COMO DEBUT DE AMILOIDOSIS VESICAL SECUNDARIA.PRESENTACIÓN DE UN NUEVO CASO Y REVISIÓN DE LA LITERATURA La amiloidosis vesical primaria es una patología infrecuente, no existiendo en el mundo más de 150 casos publicados, siendo aun más excepcional la amiloidosis vesical secundaria estando descritos alrededor de 25 casos. La amiloidosis vesical secundaria se asocia en la mayor parte de los pacientes a artritis reumatoide de larga evolución. El diagnostico clínico es difícil, siendo necesario el diagnós-tico diferencial con los tumores vesicales. El estudio patológico e inmunohistoquímico, confirma el diagnóstico. Presentamos el caso de una paciente que debuto con hematuria franca, inestabilidad hemodinámica e insuficiencia renal, que requirió tratamiento combinado, médico y quirúrgico para la resolución de su cuadro.Palabras clave: Amiloidosis Vesical. Pseudotumor vesical. ABSTRACT HEMATURIA AND SHARP RENAL FAILURE AS DEBUT OF SECONDARY BLADDER AMILOIDOSIS.PRESENTATION OF A NEW CASE AND REVISION OF THE LITERATURE The primary bladder amiloidosis is an uncommon pathology, not existing in the world more than 150 published cases, being even more exceptional the secondary bladder amiloidosis being described around 25 cases. The secondary bladder amiloidosis associates in most from the patients to arthritis reumatoide of long evolution.
