RT Journal Article SR Electronic T1 Colon cancer metastasis to the thyroid gland JF Saudi Medical Journal JO Saudi Med J FD Prince Sultan Military Medical City SP 868 OP 871 VO 35 IS 8 A1 Alherabi, Ameen Z. A1 Marglani, Osama A. A1 Gazzaz, Malak J. A1 Abbas, Mohammed M. YR 2014 UL http://smj.org.sa/content/35/8/868.abstract AB Thyroid metastasis originating from colon cancer is an uncommon clinical entity. We present a case of a 40-year-old Saudi male patient that was known to have metastatic adenocarcinoma of the colon, and who presented initially with hoarseness of voice. A left thyroid lesion was found and fine-needle aspiration biopsy showed that it was a colon cancer metastasis. His condition later deteriorated with development of stridor. Tracheostomy was performed and the diagnosis was confirmed by biopsy. A high index of suspicion is required to consider colorectal carcinoma metastatic to the thyroid.
