%X El carcinoma sarcomatoide de la gl芍ndula tiroides es un tumor raro, de curso r芍pidamente fatal y que no responde en forma favorable a ning迆n tratamiento conocido. Se presenta el caso de una paciente femenina de 64 a os de edad quien consult車 por disnea, disfagia y disfon赤a progresiva, con aumento de volumen en cuello de 4 meses de evoluci車n posterior a tiroidectom赤a total por tumor tiroideo cuya biopsia report車: leiomioma de tiroides. La revisi車n de las l芍minas histol車gicas del esp谷cimen quir迆rgico report車 carcinoma sarcomatoide. Se realiz車 radiolog赤a y tomograf赤a de cuello y t車rax, fibrobroncoscopia, gammagraf赤a tiroidea, endoscopia digestiva superior, ecograf赤a abdominal y biopsia por trucut. Despu谷s de considerar al tumor como irresecable se inici車 tratamiento con radioterapia, sin obtener una respuesta favorable. La paciente falleci車 a los 38 d赤as posterior a su ingreso. Sarcomatoid carcinoma of the thyroid gland is a rare tumor, with a rapidly fatal course, that does not respond favorably to any known treatment. We present the case of a 64 year old female patient with a 4 month history of dyspnea, dysphagia, and progressive dysphonia, with a neck mass posterior a total thyroidectomy. She had a past history of total thyroidectomy for a thyroid tumor reported as a leiomyoma four months before admission. The histologic slides from the thyroidectomy specimen were reviewed at our institution and findings were consistent with sarcomatoid carcinoma. Bronchoscopy, abdominal ultrasound, computed tomography and tru-cut core biopsy of the neck mass were performed. The patient was considered inoperable and external radiotherapy is initiated without favorable response. Patient dies 38 days after admission.
