Clinically, these lesions are mistaken for lymph node swelling or metastatic tumour. Primary carcinoma in lateral aberrant ectopic thyroid with normal active native thyroid is very uncommon. We report a case of papillary carcinoma in lateral aberrant ectopic thyroid tissue, with a completely normal native thyroid gland in a 53-year-old man, who presented with a massive swelling in the lateral aspect of the neck clinically and radiologically diagnosed as a malignant soft tissue tumour with differential diagnosis of malignant lymphoma. Fine needle aspiration cytology revealed metastatic papillary carcinoma. In toto excision of the soft tissue mass along with subtotal thyroidectomy was performed. Histology of the mass revealed papillary carcinoma of lateral aberrant ectopic thyroid, while the thyroid gland did not show evidence of malignancy. The postsurgical period was uneventful, and the patient underwent radioiodine ablation.<\/jats:p>","DOI":"10.1136\/bcr-2020-241451","type":"journal-article","created":{"date-parts":[[2021,5,11]],"date-time":"2021-05-11T12:42:02Z","timestamp":1620736922000},"page":"e241451","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":8,"title":["Massive lateral neck mass: aberrant ectopic thyroid malignancy"],"prefix":"10.1136","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2162-1709","authenticated-orcid":false,"given":"Vartika","family":"Singh","sequence":"first","affiliation":[{"name":"Department of Pathology, Nitte University K S Hegde Medical Academy, Mangalore, Karnataka, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Teerthanath","family":"Srinivas","sequence":"additional","affiliation":[{"name":"Department of Pathology, Nitte University K S Hegde Medical Academy, Mangalore, Karnataka, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shubha","family":"Bhat","sequence":"additional","affiliation":[{"name":"Department of Pathology, Nitte University K S Hegde Medical Academy, Mangalore, Karnataka, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shreya","family":"Goel","sequence":"additional","affiliation":[{"name":"Department of Pathology, Nitte University K S Hegde Medical Academy, Mangalore, Karnataka, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2021,5,11]]},"reference":[{"key":"2025082801412453000_14.5.e241451.1","doi-asserted-by":"publisher","DOI":"10.1530\/EJE-11-0461"},{"key":"2025082801412453000_14.5.e241451.2","doi-asserted-by":"publisher","DOI":"10.3346\/jkms.2008.23.3.548"},{"key":"2025082801412453000_14.5.e241451.3","article-title":"Papillary thyroid carcinoma: ectopic malignancy versus metastatic disease","volume":"2017","author":"Agosto-Vargas","year":"2017","journal-title":"Case Rep Endocrinol"},{"key":"2025082801412453000_14.5.e241451.4","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1155\/2019\/9172942","article-title":"Ectopic papillary carcinoma in the midline neck accompanied by a benign thyroid gland","volume":"2019","author":"Evans","year":"2019","journal-title":"Case Rep Otolaryngol"},{"key":"2025082801412453000_14.5.e241451.5","doi-asserted-by":"crossref","DOI":"10.1136\/bcr.02.2012.5783","article-title":"Papillary carcinoma of thyroid arising from ectopic thyroid tissue inside branchial cleft cyst: a rare case","volume":"2012","author":"Kushwaha","year":"2012","journal-title":"BMJ Case Rep"},{"key":"2025082801412453000_14.5.e241451.6","doi-asserted-by":"crossref","first-page":"59","DOI":"10.1007\/s12262-011-0308-4","article-title":"Ectopic thyroid tissue masquerading as a lateral neck mass: a case report","volume":"75","author":"Ravishankaran","year":"2013","journal-title":"Indian J Surg"},{"key":"2025082801412453000_14.5.e241451.7","first-page":"349","article-title":"A case of branchial cyst with an ectopic thyroid papillary carcinoma","volume":"75","author":"Cappellani","year":"2004","journal-title":"Ann Ital Chir"},{"key":"2025082801412453000_14.5.e241451.8","doi-asserted-by":"publisher","DOI":"10.1016\/S1726-4901(10)70046-0"},{"key":"2025082801412453000_14.5.e241451.9","doi-asserted-by":"crossref","first-page":"12","DOI":"10.1016\/S0196-0709(96)90036-8","article-title":"Evolution and evaluation of lateral cystic neck masses containing thyroid tissue: \"lateral aberrant thyroid\" revisited","volume":"17","author":"Rabinov","year":"1996","journal-title":"Am J Otolaryngol"},{"key":"2025082801412453000_14.5.e241451.10","article-title":"Cervical lymphadenopathy: metastasis of papillary carcinoma or ectopic thyroid tissue?","volume":"2012","author":"Simion","year":"2012","journal-title":"BMJ Case Rep"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2020-241451","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,28]],"date-time":"2025-08-28T08:41:36Z","timestamp":1756370496000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2020-241451"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2021,5]]},"references-count":10,"journal-issue":{"issue":"5","published-online":{"date-parts":[[2021,5,11]]},"published-print":{"date-parts":[[2021,5]]}},"alternative-id":["10.1136\/bcr-2020-241451"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2020-241451","relation":{},"ISSN":["1757-790X"],"issn-type":[{"value":"1757-790X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2021,5]]}}}
