Physical examination revealed a 4\u00d74\u2009cm thyroid mass, facial plethora and dorsocervical fat pads. Laboratory investigations confirmed hypercortisolism with elevated cortisol and Adrenocorticotropic Hormone(ACTH), with non-suppression on dexamethasone suppression tests. Imaging studies identified a malignant thyroid mass and bulky adrenal glands. Fine-needle aspiration cytology confirmed medullary thyroid carcinoma (MTC) with significantly elevated calcitonin and carcinoembryonic antigen. The patient was diagnosed with ectopic Cushing\u2019s syndrome secondary to MTC and underwent bilateral adrenalectomy followed by total thyroidectomy. Postoperatively, ACTH levels normalised; however, residual tumour was detected, necessitating external beam radiotherapy.<\/jats:p>","DOI":"10.1136\/bcr-2024-262801","type":"journal-article","created":{"date-parts":[[2024,12,4]],"date-time":"2024-12-04T20:35:30Z","timestamp":1733344530000},"page":"e262801","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":3,"title":["Malignant thyroid neoplasm with ectopic Cushing\u2019s syndrome"],"prefix":"10.1136","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7247-5492","authenticated-orcid":false,"given":"Vivek","family":"Jha","sequence":"first","affiliation":[{"name":"Endocrinology, PGIMER, Chandigarh, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0410-8778","authenticated-orcid":false,"given":"Sanjay","family":"Bhadada","sequence":"additional","affiliation":[{"name":"Endocrinology, PGIMER, Chandigarh, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9701-9554","authenticated-orcid":false,"given":"Liza","family":"Das","sequence":"additional","affiliation":[{"name":"Endocrinology, PGIMER, Chandigarh, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Siddhartha","family":"Madhad","sequence":"additional","affiliation":[{"name":"Endocrinology, PGIMER, Chandigarh, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2024,12,4]]},"reference":[{"key":"2025082711562551000_17.12.e262801.1","doi-asserted-by":"publisher","DOI":"10.1210\/er.19.5.647"},{"key":"2025082711562551000_17.12.e262801.2","doi-asserted-by":"publisher","DOI":"10.1016\/j.tem.2007.03.005"},{"key":"2025082711562551000_17.12.e262801.3","doi-asserted-by":"publisher","DOI":"10.1089\/thy.2014.0335"},{"key":"2025082711562551000_17.12.e262801.4","doi-asserted-by":"publisher","DOI":"10.1089\/thy.2005.15.618"},{"key":"2025082711562551000_17.12.e262801.5","doi-asserted-by":"publisher","DOI":"10.1016\/S0889-8529(01)00025-1"},{"key":"2025082711562551000_17.12.e262801.6","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2265.1994.tb02486.x"},{"key":"2025082711562551000_17.12.e262801.7","doi-asserted-by":"publisher","DOI":"10.1007\/s00268-001-0032-5"},{"key":"2025082711562551000_17.12.e262801.8","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM199809243391304"},{"key":"2025082711562551000_17.12.e262801.9","doi-asserted-by":"crossref","first-page":"3055","DOI":"10.1210\/jc.2013-4340","article-title":"Vandetanib successfully controls medullary thyroid cancer-related Cushing syndrome in an adolescent patient","volume":"99","author":"Nella","year":"2014","journal-title":"J Clin Endocrinol Metab"},{"key":"2025082711562551000_17.12.e262801.10","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1097-0142(20000301)88:5<1139::AID-CNCR26>3.0.CO;2-Z"},{"key":"2025082711562551000_17.12.e262801.11","doi-asserted-by":"crossref","first-page":"234","DOI":"10.1002\/jso.25761","article-title":"Outcomes of surgery and postoperative radiation therapy in managing medullary thyroid carcinoma","volume":"121","author":"Groen","year":"2020","journal-title":"J Surg Oncol"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2024-262801","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,27]],"date-time":"2025-08-27T18:56:34Z","timestamp":1756320994000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2024-262801"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2024,12]]},"references-count":11,"journal-issue":{"issue":"12","published-online":{"date-parts":[[2024,12,4]]},"published-print":{"date-parts":[[2024,12]]}},"alternative-id":["10.1136\/bcr-2024-262801"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2024-262801","relation":{},"ISSN":["1757-790X"],"issn-type":[{"value":"1757-790X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2024,12]]}}}
