Leiomiosarcoma pulmonar primario: presentación de un caso / Primary pulmonary leiomyosarcoma - A case report

Los sarcomas son tumores mesenquimatosos que tienen su origen en los componentes de estroma de la pared bronquial o en el intersticio del parénquima pulmonar. Las neoplasias sarcomatosas pulmonares son un grupo de tumores muy poco frecuentes y difíciles de diagnosticar. Constituyen tan solo el 0,2-0,5% del total de enfermedades malignas primarias del pulmón. Los leiomiosarcomas pulmonares primarios se subdividen en los que se originan en el parénquima pulmonar, los derivados del árbol bronquial y los que proceden de arterias pulmonares. Presentamos aquí el caso de una mujer afroamericana de 43 años que presentaba tos crónica, fatiga y pérdida de peso. La detección temprana es la clave del tratamiento eficaz de estos pacientes. La opción de tratamiento existente es la resección completa del tumor. Estos casos proporcionan una yuxtaposición interesante con el tratamiento del cáncer de pulmón habitual(AU)

Sarcomas are mesenchymal tumors that originate from the stromal elements of the bronchial wall or from interstices of lung parenchyma. Pulmonary sarcomatous neoplasms are a rare and diagnostically challenging group of tumors. They constitute only 0.2%-0.5% of all primary lung malignancies. Primary pulmonary leiomyosarcomas are subdivided into those originating from pulmonary parenchyma, bronchial tree or pulmonary arteries. Here we present a case of 43-year-old African-American female who with chronic cough, fatigue and weight loss. Early detection is the key to the successful management of these patients. The available treatment option is complete resection of tumor. These cases provide an interesting juxtaposition to the management of typical lung cancer(AU)
