Most AMBs were located between the tip and cecal limit, 7 at the tip, and 1 at the cecal limit of the appendectomy specimen. Associated appendix lesions were: acute appendicitis, neuroma, mesoappendix cyst, muscle hiatus, and diverticulae (60,6,2,45, and 1, respectively). In 24 appendices, the AMB developed from the perihiatus muscle. Two microscopy types of AMBs were detected: muscle\u2010AMB and mesoappendix\u2010AMB.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>AMB may be detected incidentally at microscopy of appendectomy specimens. Acute appendicitis was associated in most cases, independently on the microscopy type of AMB. Appendix abnormalities as neuroma, mesoappendix cyst, muscle hiatus, and diverticulae can be associated to AMBs.<\/jats:p><\/jats:sec>","DOI":"10.1002\/ca.23689","type":"journal-article","created":{"date-parts":[[2020,9,29]],"date-time":"2020-09-29T13:00:49Z","timestamp":1601384449000},"page":"673-677","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Appendix muscle bands, a forgotten entity"],"prefix":"10.1002","volume":"34","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3816-058X","authenticated-orcid":false,"given":"Adriana","family":"Handra\u2010Luca","sequence":"first","affiliation":[{"name":"Service d'Anatomie pathologique, APHP GHU Avicenne Universite Paris Nord Sorbonne Cite  Bobigny France"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2020,10,9]]},"reference":[{"doi-asserted-by":"publisher","key":"e_1_2_9_2_1","DOI":"10.1002\/ca.980080312"},{"doi-asserted-by":"publisher","key":"e_1_2_9_3_1","DOI":"10.1002\/ca.22269"},{"doi-asserted-by":"publisher","key":"e_1_2_9_4_1","DOI":"10.4293\/108680810X12785289144881"},{"doi-asserted-by":"publisher","key":"e_1_2_9_5_1","DOI":"10.5152\/eurasianjmed.2017.17218"},{"doi-asserted-by":"publisher","key":"e_1_2_9_6_1","DOI":"10.1097\/00000658-194201000-00004"},{"doi-asserted-by":"publisher","key":"e_1_2_9_7_1","DOI":"10.1097\/00000658-191507000-00007"},{"doi-asserted-by":"publisher","key":"e_1_2_9_8_1","DOI":"10.1002\/ca.20587"},{"doi-asserted-by":"publisher","key":"e_1_2_9_9_1","DOI":"10.1002\/ca.23474"},{"doi-asserted-by":"publisher","key":"e_1_2_9_10_1","DOI":"10.1007\/s00595-004-2821-6"},{"doi-asserted-by":"publisher","key":"e_1_2_9_11_1","DOI":"10.1177\/000313481207800424"},{"key":"e_1_2_9_12_1","first-page":"2892","volume-title":"Rosai and Ackerman's surgical pathology","author":"Rosai J.","year":"2011"},{"issue":"1","key":"e_1_2_9_13_1","first-page":"23","article-title":"Unusual entities of appendix mimicking appendicitis clinically\u2014emphasis on diagnosis and treatment","volume":"12","author":"Singal R.","year":"2017","journal-title":"Maedica (Buchar)"}],"container-title":["Clinical Anatomy"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/ca.23689","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/full-xml\/10.1002\/ca.23689","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/ca.23689","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,8,30]],"date-time":"2023-08-30T17:47:41Z","timestamp":1693417661000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/ca.23689"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2020,10,9]]},"references-count":12,"journal-issue":{"issue":"5","published-print":{"date-parts":[[2021,7]]}},"alternative-id":["10.1002\/ca.23689"],"URL":"https:\/\/doi.org\/10.1002\/ca.23689","archive":["Portico"],"relation":{},"ISSN":["0897-3806","1098-2353"],"issn-type":[{"type":"print","value":"0897-3806"},{"type":"electronic","value":"1098-2353"}],"subject":[],"published":{"date-parts":[[2020,10,9]]},"assertion":[{"value":"2020-05-26","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2020-09-19","order":1,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2020-10-09","order":2,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
