The mass was associated with cyclical pain coinciding with menses. Her abnormal bleeding failed conservative management with an intrauterine device and oral contraceptive pills. Physical examination revealed a Pfannenstiel scar with a 4\u00d76 cm midline mass with overlying discolouration. The patient subsequently underwent surgical excision of the caesarean scar endometrioma with resection of the involved tissue and abdominal wall reconstruction using advancement skin flaps. Histopathologic evaluation confirmed extensive endometriosis within the caesarean scar. Surgical scar endometriosis is a rare but recognised complication of caesarean delivery, one of the most frequently performed surgical procedures in the USA. Definitive treatment involves complete surgical excision and, when necessary, abdominal wall reconstruction.<\/jats:p>","DOI":"10.1136\/bcr-2025-268827","type":"journal-article","created":{"date-parts":[[2026,1,12]],"date-time":"2026-01-12T15:30:40Z","timestamp":1768231840000},"page":"e268827","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Abdominal wall endometriosis in a caesarean section scar"],"prefix":"10.1136","volume":"19","author":[{"given":"Alyssa","family":"Galloway","sequence":"first","affiliation":[{"name":"Department of OB\/Gyn, Hackensack Meridian Jersey Shore University Medical Center, Neptune City, New Jersey, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6106-5324","authenticated-orcid":false,"given":"Nicole","family":"Cumbo","sequence":"additional","affiliation":[{"name":"Department of OB\/Gyn, Hackensack Meridian Jersey Shore University Medical Center, Neptune City, New Jersey, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiu","family":"Sun","sequence":"additional","affiliation":[{"name":"Department of Pathology, Hackensack Meridian Health Jersey Shore University Medical Center, Neptune, NJ, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3182-0808","authenticated-orcid":false,"given":"Karim","family":"ElSahwi","sequence":"additional","affiliation":[{"name":"Division of Gynecologic Oncology, Department of OB-GYN, Hackensack Meridian Health Jersey Shore University Medical Center, Neptune, NJ, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2026,1,12]]},"reference":[{"key":"2026011207301542000_19.1.e268827.1","doi-asserted-by":"crossref","DOI":"10.3390\/jcm11040995","article-title":"Umbilical Endometriosis: A Systematic Literature Review and Pathogenic Theory Proposal","volume":"11","author":"Dridi","year":"2022","journal-title":"J Clin Med"},{"key":"2026011207301542000_19.1.e268827.2","doi-asserted-by":"publisher","DOI":"10.1002\/rmb2.12340"},{"key":"2026011207301542000_19.1.e268827.3","doi-asserted-by":"crossref","first-page":"64","DOI":"10.3892\/br.2020.1371","article-title":"Cases of abdominal wall endometriosis distinguished from soft tissue tumors: A report of three cases","volume":"13","author":"Hagi","year":"2020","journal-title":"Biomed Rep"},{"key":"2026011207301542000_19.1.e268827.4","doi-asserted-by":"crossref","DOI":"10.1136\/bcr-2024-262465","article-title":"Surgical management of umbilical endometrioma within an umbilical hernia","volume":"18","author":"Cumbo","year":"2025","journal-title":"BMJ Case Rep"},{"key":"2026011207301542000_19.1.e268827.5","article-title":"Skin Endometriosis at the Caesarean Section Scar: A Case Report and Review of the Literature","volume":"10","author":"Alnafisah","year":"2018","journal-title":"Cureus"},{"key":"2026011207301542000_19.1.e268827.6","doi-asserted-by":"publisher","DOI":"10.7150\/ijms.38679"},{"key":"2026011207301542000_19.1.e268827.7","doi-asserted-by":"crossref","DOI":"10.1177\/2050313X241237333","article-title":"Abdominal wall endometriosis in cesarean scar: A case report","volume":"12","author":"Kyejo","year":"2024","journal-title":"SAGE Open Med Case Rep"},{"key":"2026011207301542000_19.1.e268827.8","doi-asserted-by":"crossref","first-page":"14","DOI":"10.1186\/s12905-019-0711-8","article-title":"Cesarean scar endometriosis: presentation of 198 cases and literature review","volume":"19","author":"Zhang","year":"2019","journal-title":"BMC Womens Health"},{"key":"2026011207301542000_19.1.e268827.9","doi-asserted-by":"crossref","unstructured":"Radswiki T , Elfeky M , Amer M , et al .
