Abstract: A case is presented of a 57-year-old man consulting for chronic diarrhea. Based on subsequent findings (thyroid nodule and metastases), the possibility of metastatic medullary thyroid carcinoma (MTC) was raised. Thyroidectomy allowed diagnosing a multicentric left lobe MTC. MTC is a rare cause of diarrhea, but should be considered, especially in the presence of signs or symptoms of alarm or nonresponse to empirical therapy.<br />Competing Interests: Sponsorships or competing interests that may be relevant to content are disclosed at the end of this articleThe authors declare no conflicts of interest.<br /> (Copyright © 2018 The Authors.
