Exophytic gastric leiomyoma with retroperitoneal growth

Leiomioma gástrico exofítico a crecimiento retroperitoneal

A. Praderi, Luis - Maquieira, Gonzalo - F. Cassinelli, Juan

Resumen:

A rare gastric tumor, the leiomyoma with very large exophitic growth, has the appearence of large retroperitoneal tumors.It is a gastric tumor and presents no symptoms on the viscus on which it is appended; causing only sub-occlusion of colon.Radiologically, it is an opaque tumor, of the retrocavity, corresponding to the area of the body of the pancreas and extends upwards opening the left colic angle, instead of closing it. It is a rare lesional association of a slow-growth gastric tumor and acute lithiasic cholecystitis in the perforative stage, which explains the infectious syndrone and simulates a secondary liver.The patient was informed of the existence of a benign tumor so as to prepare him for the second, more serious, operation.Was treated with two-step surgery; the first, septic; the second with unavoidable colonic resection due to involvement of its nutrional vessels.The tumor is histologically benign but due to is vascular damage (and eventual metastases) it is decided to classify it as a leiomyosarcoma withreserved prognosis.


Es un tumor gástrico poco frecuente, leiómioma a gran crecimiento exofítico, con la apariencia de los grandes tumores retroperitoneales.No da sintomatología sobre la víscera en que asienta,y se traduce por su.boclusión de colon.Radiológicamente es tumor opaco, de la retrocavidad, que corresponde a la zoa del cuerpo del páncreas y que despliega hacia arriba, abriendo el ángulo c'lico izquierdo, en lugar de cerrarlo.Existía una rara asociación de tumor gástrico a crecimiento lento, y colecistitis aguda litiásica en etapa preperforativa que explica el síndrome. infeccioso y simula el hígado secundario.Se planteó al enfermo la existencia de un tumor benigno, para prepararlo a la segund/ intervención de mayor entidad.Se adoptó una conducta quirúrgica en dos tiempos, el primero séptico, el segundo con una resección colónica obligada por compromiso de sus vasos nutricios.El tumor era histológicamente benigno, pero dado el sufrimiento vascular ( eventualmente metastasiante) se decide clasificarlo como leiomiosarcoma de pronóstico reservado.
