ABSTRACT
El leiomiosarcoma es un tumor que puede localizarse en tejidos blandos o en órganos. El tratamiento consiste en la resección quirúrgica completa del tumor. El pronóstico es difícil de predecir y después de un largo período sin enfermedad pueden aparecer metástasis a distancia. Las metástasis pulmonares son frecuentes, pero su localización en bronquios principales con atelectasia pulmonar es muy rara. Presentamos 2 casos de atelectasia pulmonar y neumonitis obstructiva secundaria a metástasis en bronquios principales de un leiomiosarcoma de útero y de un leiomiosarcoma de muslo, respectivamente, que tratamos con resección endoscópica. Analizamos el papel del tratamiento endoscópico con láser para paliar los síntomas y como ayuda previa a la realización de otro tipo de tratamiento oncológico(AU)
Leiomyosarcoma is a cancer that can affect the soft tissues or organs. The standard treatment is complete tumor resection. Prognosis is difficult to predict and distant metastases can occur after a long disease-free period. Lung metastases are common but metastasis to the main bronchi with pulmonary atelectasis is very rare. We describe 2 cases of pulmonary atelectasis and obstructive pneumonitis due to metastasis to the main bronchi from leiomyosarcoma of the uterus in one of the patients and leiomyosarcoma of the thigh in the other. Both patients were treated with endoscopic resection. We discuss the role of endoscopic laser treatment in the palliation of symptoms and as an initial procedure before other cancer treatments are started(AU)
