We describe a case of Cushing's syndrome caused by a medullary thyroid carcinoma (MCT) secreting corticotropin-releasing-hormone (CRH) in a young woman presenting mucosal neuromas located on the top of the tongue and eyelid areas. Laboratory studies showed, basally and after dexamethasone suppression test, serum cortisol and plasma pituitary corticotrophin (ACTH) levels agreed with an ectopic Cushing's syndrome. Immunohistochemical studies of the MCT tissue revealed a production of CRH and scattered cells containing vasopressin but not ACTH peptides. This is the first demonstrated case of a CRH-secreting tumor in multiple endocrine neoplasia (MEN IIB) syndrome.

A 31 year old woman was diagnosed with multiple endocrine neoplasia (MEN) 2B at 10 years old. Dark pigmentation gradually developed on her skin and her serum adrenocorticotropic hormone (ACTH) was high, suggesting concurrent ectopic ACTH syndrome (EAS). Corticotropin-releasing hormone (CRH) loading test ruled out Cushing's disease and supported the diagnosis of EAS. Multiple low attenuation mass in the liver was observed in a computed tomography (CT) scan, and was suspected as ectopic ACTH-secreting metastatic tumor from medullary thyroid carcinoma (MTC). ACTH production by MTC is relatively rare, particularly in patients with MEN; patients with ectopic ACTH-secreting liver metastatic tumor from MTC in MEN 2B have never been reported previously.
