Tumor estromal intestinal

Los tumores estromales son un tipo de neoplasias de distintas lineas de diferenciacion y de muy diverso comportamiento clinico. Son tumores mesenquimatosos originados en la pared muscular de visceras huecas. Debido a su baja incidencia, existen pocas series publicadas. Tambien es conocida la dificultad de predecir el riesgo de que estos tumores metasticen. Los criterios para determinar el grado de malignidad de los tumores estromales no estan claramente definidos, por lo que el tratamiento quirurgico de estas lesiones es controvertido. Generalmente se recomienda la reseccion completa pero limitada de estos tumores, dada la menor complejidad tecnica, la menor morbilidad y el identico pronostico al de las resecciones mas amplias. Stromal tumors are a type of neoplasias of various lines of differentiation and of very diverse clinical behavior. They are mesenchymatous tumors originated on the muscular wall of hollow viscera. Due to their low incidence, a few series have been published. It is also known the difficulty to predict their risk for metastasizing. The criteria to determine the malignancy degree of the stromal tumors have not been clearly defined. That's why, the surgical treatment of these lesions is controverted. Generally, it is recommended the complete but limited resection of these tumors, taking into account the minor technical complexity, the lower morbidity and the prognosis identical to that of the wider resections.
