Thyroid papillary carcinoma coexisted with chondrosarcoma originated from cricoid cartilage

Abstract

The patient was a 62-year-old man who presented with a 5-year history of hoarseness; he visited us at the NTT Medical Center Tokyo in March 2011. Bilateral vocal cord paralysis and a solid anterior neck mass were found. Fine needle aspiration cytology from his neck mass showed papillary carcinoma. He was diagnosed as thyroid cancer with gross laryngeal invasion, and was hospitalized in April 2011 for surgery. Total laryngectomy, total thyroidectomy, and bilateral neck dissection were performed. Histological diagnosis was thyroid papillary carcinoma co-existing with chondrosarcoma originating from cricoid cartilage. Laryngeal chondrosarcoma is a rare entity and to our knowledge this is the first case report of laryngeal chondrosarcoma co-existing with another malignant neoplasm.
