Failure to recognize this anomaly may result in incomplete thyroidectomy, particularly in patients with thyroid malignancy. We report two consecutive cases of double PL identified intraoperatively within a 2-day interval at a single center. The index case was a 51-year-old woman operated on for a suspicious thyroid nodule, with final pathology revealing classic variant papillary thyroid carcinoma (2.3\u00a0cm) with central lymph node metastases (pT2N1a, AJCC 8th edition). Two distinct PLs arising from the isthmus were identified and completely excised. Two days later, a 55-year-old man with multinodular goiter and a history of asthma underwent thyroidectomy, during which an identical double PL configuration was detected and removed. In both cases, preoperative ultrasonography failed to identify the PLs. The occurrence of two consecutive cases suggests that double PL may be underrecognized rather than truly exceptional. Systematic exploration of the prelaryngeal region is essential to ensure complete thyroidectomy and optimal oncologic outcomes.<\/jats:p>","DOI":"10.1093\/jscr\/rjag049","type":"journal-article","created":{"date-parts":[[2026,1,20]],"date-time":"2026-01-20T12:27:47Z","timestamp":1768912067000},"source":"Crossref","is-referenced-by-count":2,"title":["Double pyramidal lobe of the thyroid gland: report of two consecutive cases with surgical and oncologic implications"],"prefix":"10.1093","volume":"2026","author":[{"given":"Enver Tansu","family":"A\u011far","sequence":"first","affiliation":[{"name":"Department of Surgical Oncology, University of Health Sciences Mersin Training and Research Hospital , Korukent Mah. 96015 Sok., Mersin Entegre Sa\u011fl\u0131k Kamp\u00fcs\u00fc, 33240 Toroslar, Mersin ,","place":["T\u00fcrkiye"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0997-0268","authenticated-orcid":false,"given":"Cemil","family":"Y\u00fcksel","sequence":"additional","affiliation":[{"name":"Department of Surgical Oncology, University of Health Sciences Mersin Training and Research Hospital , Korukent Mah. 96015 Sok., Mersin Entegre Sa\u011fl\u0131k Kamp\u00fcs\u00fc, 33240 Toroslar, Mersin ,","place":["T\u00fcrkiye"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2026,2,8]]},"reference":[{"key":"2026020807412882500_ref1","doi-asserted-by":"crossref","first-page":"41","DOI":"10.4103\/0022-3859.48440","article-title":"Double pyramidal thyroid lobe","volume":"55","author":"Ignjatovi\u0107","year":"2009","journal-title":"J Postgrad Med"},{"key":"2026020807412882500_ref2","doi-asserted-by":"publisher","first-page":"384148","DOI":"10.1155\/2015\/384148","article-title":"Pyramidal lobe of the thyroid gland: surgical anatomy in patients undergoing total thyroi-dectomy","volume":"2015","author":"Gurleyik","year":"2015","journal-title":"Anat Res Int"},{"key":"2026020807412882500_ref3","doi-asserted-by":"publisher","first-page":"309","DOI":"10.1159\/000430894","article-title":"Pyramidal lobe of the thyroid: anatomical considerations of importance in thyroid cancer surgery","volume":"38","author":"Sinos","year":"2015","journal-title":"Oncol Res Treat"},{"key":"2026020807412882500_ref4","doi-asserted-by":"publisher","first-page":"32","DOI":"10.4274\/Mirt.09719","article-title":"Scintigraphic evaluation of thyroid pyramidal lobe","volume":"22","author":"Cengiz","year":"2013","journal-title":"Mol Imaging Radionucl Ther"},{"key":"2026020807412882500_ref5","first-page":"110","article-title":"Surgical anatomy of the pyramidal lobe and its significance in thyroid surgery","volume":"49","author":"Zivic","year":"2011","journal-title":"S Afr J Surg"},{"key":"2026020807412882500_ref6","first-page":"171","article-title":"Why does the patient with Graves\u2019 disease remain euthyroid\/mildly hyperthyroid following total thyroidectomy\u2014the role of thyrotropin receptor antibodies (TRAb) and vestigial remnants of the thyroglossal tract","volume":"47","author":"Cigrovski-Berkovic","year":"2008","journal-title":"Acta Clin Croat"}],"container-title":["Journal of Surgical Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/academic.oup.com\/jscr\/article-pdf\/2026\/2\/rjag049\/66803651\/rjag049.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"syndication"},{"URL":"https:\/\/academic.oup.com\/jscr\/article-pdf\/2026\/2\/rjag049\/66803651\/rjag049.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,2,8]],"date-time":"2026-02-08T12:41:35Z","timestamp":1770554495000},"score":1,"resource":{"primary":{"URL":"https:\/\/academic.oup.com\/jscr\/article\/doi\/10.1093\/jscr\/rjag049\/8467068"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,1,31]]},"references-count":6,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2026,1,31]]}},"URL":"https:\/\/doi.org\/10.1093\/jscr\/rjag049","relation":{},"ISSN":["2042-8812"],"issn-type":[{"value":"2042-8812","type":"electronic"}],"subject":[],"published-other":{"date-parts":[[2026,2]]},"published":{"date-parts":[[2026,1,31]]},"article-number":"rjag049"}}
