Many of these lesions are congenital and do not require treatment, if asymptomatic. Special attention is to be paid when imaging findings are not typical. In such cases, definitive diagnostic can require surgical excision. To this day, ectopic thyroid tissue was not part of known differential diagnosis. This is the first reported case of thyroid adenoma found in the perirectal area. Ectopic thyroid gland can progress over time and include malignant transformation, although rare. It needs to be considered when managing these cases, especially in unusual locations. This case report offers a systematic approach to the atypical pararectal tumor. It shares new specific clinical experience in managing a case\u00a0 of pararectal ectopic thyroid adenoma, from both a surgical and a histopathological point of view.<\/jats:p>","DOI":"10.1093\/jscr\/rjad515","type":"journal-article","created":{"date-parts":[[2023,10,1]],"date-time":"2023-10-01T23:59:33Z","timestamp":1696204773000},"source":"Crossref","is-referenced-by-count":0,"title":["En bloc resection of pararectal ectopic thyroid tissue: a case report"],"prefix":"10.1093","volume":"2023","author":[{"ORCID":"https:\/\/orcid.org\/0009-0009-8327-3525","authenticated-orcid":false,"given":"Janyssa","family":"Charbonneau","sequence":"first","affiliation":[{"name":"Surgery Department, Laval University , Quebec City, Quebec, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"V\u00e9ronique","family":"Lefebvre","sequence":"additional","affiliation":[{"name":"Anatomopathology Department, Laval University , Quebec City, Quebec, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Philippe","family":"Bouchard","sequence":"additional","affiliation":[{"name":"Surgery Department, Laval University , Quebec City, Quebec, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2023,9,30]]},"reference":[{"key":"2023100123592590400_ref1","doi-asserted-by":"crossref","first-page":"rjz331","DOI":"10.1093\/jscr\/rjz331","article-title":"Pararectal angiomyxoma: a diagnostic dilemma","volume":"2019","author":"Dalvi","year":"2019","journal-title":"J Surg Case Rep"},{"key":"2023100123592590400_ref2","doi-asserted-by":"crossref","first-page":"824","DOI":"10.1007\/s00261-014-0119-8","article-title":"Benign and malignant tumors of the rectum and perirectal region","volume":"39","author":"Purysko","year":"2014","journal-title":"Abdom Imaging"},{"key":"2023100123592590400_ref3","first-page":"223","article-title":"Management of ectopic thyroid in head and neck: study of 8 cases","volume":"33","author":"Agrawal","year":"2021","journal-title":"Iran J Otorhinolaryngol"},{"key":"2023100123592590400_ref4","doi-asserted-by":"crossref","first-page":"S3","DOI":"10.1016\/j.ijsu.2014.05.076","article-title":"Morphological, diagnostic and surgical features of ectopic thyroid gland: a review of literature","volume":"12","author":"Guerra","year":"2014","journal-title":"Int J Surg"},{"key":"2023100123592590400_ref5","doi-asserted-by":"crossref","first-page":"94","DOI":"10.1016\/j.ijscr.2017.09.008","article-title":"Follicular adenoma in ectopic thyroid.
