CASTRO, ROBERTO C. et al. Carcinoma Sarcomatoide de la glándula tiroides: a propósito de un caso. Rev. venez. oncol. [online]. 2005, vol.17, n.4, pp.217-220. ISSN 0798-0582.

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.
