ABSTRACT

Los leiomiosarcomas de la cavidad nasal y senos paranasales son neoplasias malignas de baja frecuencia, localmente agresivas. Presentan una alta tendencia a la recurrencia de aproximadamente 55% en nariz y senos paranasales. Están conformados por células musculares lisas. Según diversos autores, aproximadamente el 50% de los pacientes mueren antes del primer año y la supervivencia a los 5 años es del 20%. Anteriormente se pensaba que no poseían potencial metastásico, sin embargo, en series actuales se ha visto que presentan un alto poder metastásico de hasta el 50%. Las metástasis se presentan de forma tardía. El tratamiento recomendado consiste en la resección radical del tumor primario con un amplio margen de tejido normal y la radioterapia es de uso controversial en el manejo.


Leiomyosarcoma of the nasal cavity and paranasal sinuses are malignant, low frequency, locally aggressive neoplasm. They present a high tendency to recurrence of approximately 55% in the nose and paranasal sinuses. They are made up of smooth muscle cells. According to different authors, approximately 50% of patients die before the first year and survival at 5 years is 20%. Previously it was thought that they did not possess metastatic potential, however in current series it has been seen that they have a high metastatic power of up to 50%. Metastases present late. The recommended treatment consists of radical resection of the primary tumor with a wide margin of normal tissue.
