ABSTRACT

RESUMEN Los Schwannomas son tumores de origen neural, corresponden al 1 por ciento de los tumores de retroperitoneo. En la mayoría de las ocasiones, son tumores de comportamiento benigno, encontrando que solo del 5 - 18 por ciento son malignos y aún menos frecuente es que sean de alto grado en su histología. Se trata de una paciente de 46 años de edad sin antecedentes crónico degenerativos. Con diagnóstico conocido de neurofibromatosis tipo I. Inició su padecimiento actual tres años previos a su ingreso en 2013, al presentar artralgia de rodilla derecha la cual se asocia a mialgias de forma ipsilateral. Se le solicitó como apoyo diagnostico una resonancia magnética de columna dorsal y lumbar, en la que se reporta una tumoración en la región del retroperitoneo de lado derecho con medidas de 10 x 17 cm con aparente origen espinal en L2 y L3. A pesar de ser masas de origen neural benignas la mayoría de las veces, no es infrecuente su malignización encontrando una cavidad con estructuras vecinas tomada por el tumor. En estos casos, es de vital importancia el manejo preoperatorio de manera multidisciplinaria tanto en la preparación preoperatoria, así como durante el procedimiento quirúrgico(AU)


ABSTRACT Schwannomas are tumors of neural origin and account for 1 percent of retroperitoneal tumors. In many times, they are benign tumors and just 5 to 8 percent are malignant; high degree is even less frequent in its histology. This is a male patient aged 46 years with no history of chronic degenerative problems and diagnosis of type I neurofibromatosis. The disease appeared three years before his admission to hospital in 2013 because of right knee arthralgia associated to myalgias on the same side. Diagnostic support was requested in terms of performance of magnetic resonance of dorsal and lumbar spine; this test reported the presence of a tumor in the right side of the retroperitoneal region, it measured 10 x 17 cm with apparent spinal origin in L2 and L3. Although they are often masses of benign neural origin, their malignization is not rare. There was a cavity with adjoining structures affected by the tumor. In this type of cases, the preoperative management with multidisciplinary involvement both in the preoperative preparation and during the surgical procedure is of vital importance(AU)

ABSTRACT

The case was an 18-year-old female with progressive crampy abdominal pain, nausea and vomiting, initiated from 4 months ago, Who had 4-5 Kg weight loss in this period. In physical examination, an ill-defined mass with mild tenderness in periumblical region palpation was detected. In upper GI endoscopy, bulging folds with a necrotic mass in D2- D3 were detected. In small bowel series study, cut off of barium in D2-D3 portions was seen. For better evaluation spiral CT was performedin which a large mass with extension to small bowel in retroperitoneum was seen. In Pathologic study, classification granuloma compatible with tuberculosis was reported. This finding was confirmed with Ziel Neelsen staining and PCR

ABSTRACT

Se presentan 30 casos de tumores primarios retroperitoneales de origen mesenquimático, en un período de 11 años, correspondiendo 17 al sexo femenino y 13 al masculino. Los síntomas y signos tuvieron un promedio de 10,8 meses desde su inicio hasta el momento del diagnóstico. Fueron 21 tumores malignos y 9 benignos, siendo los liposarcomas y neurilemomas los más frecuentes respectivamente. Todos fueron intervenidos quirúrgicamente realizándose extirpación completa en 21, parcial en 4 y sólo biopsia en 5. Se analizan las intervenciones agregadas y sus resultados en cuanto a mortalidad intraoperatoria y global. Se presentan los tratamientos coadyudantes como quimioterapia y radioterapia, mostrando los esquemas usados en cada uno de ellos
