Thyroid carcinosarcoma, a rare and aggressive histotype: A case report

Abstract

Thyroid carcinosarcoma is a rare and aggressive thyroid tumor. Histological examination of a tumor showed the characteristic of epithelial carcinoma and mesenchymal differentiation. We retrospectively analyzed the course of the patient and reviewed the literature in which only 19 other cases are described. Carcinosarcoma of the thyroid is a very aggressive tumor with a clinical course similar to anaplastic thyroid carcinoma. Survival is very short despite aggressive multimodal treatment.
