Medullary thyroid carcinomas (MTC) constitute about 5 to 7 % of thyroid neoplasms. They originate from parafollicular C-cells which can secrete adrenocorticotropic hormone (ACTH) and/or corticotropin-releasing factor (CRF) in abnormally high concentrations, potentially causing paraneoplastic Cushing's Syndrome (CS).
We report on a 42-year-old male patient with a ten year history of metastatic medullary thyroid carcinoma suffering from paraneoplastic Cushing's Syndrome caused by ectopic hypersecretion of ACTH and a simultaneous Cortisol producing adrenal metastasis.
