A woman in her late 30s presented with a painful lump beneath her caesarean section skin scar, worsening during menstruation. Despite a previous incision and drainage procedure for a \u2018scar abscess\u2019, the symptoms persisted. Ultrasound imaging revealed a cystic lesion beneath the scar. A diagnosis of scar endometriosis was made, and surgical excision was performed. The patient remained symptom-free at 2-year follow-up postsurgery. Histopathology confirmed the presence of endometrial glands and stroma within the scar tissue. This case demonstrates that a reliable diagnosis of caesarean section endometriosis could be made with a triad of symptoms of a cyclic painful mass at the site of a caesarean section scar. Imaging is helpful in excluding other differential diagnoses. Diagnosis can be confirmed with histopathology and treated with complete surgical excision.<\/jats:p>","DOI":"10.1136\/bcr-2024-261053","type":"journal-article","created":{"date-parts":[[2024,11,2]],"date-time":"2024-11-02T23:05:20Z","timestamp":1730588720000},"page":"e261053","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":1,"title":["Caesarean scar endometriosis: how to make an accurate diagnosis"],"prefix":"10.1136","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3214-4415","authenticated-orcid":false,"given":"Senapathige Nilan Kalidasa","family":"Rodrigo","sequence":"first","affiliation":[{"name":"Clinical Sciences, General Sir John Kotelawala Defence University Faculty of Medicine, Ratmalana, Sri Lanka"},{"name":"Obstetrics and Gynaecology, Navy General Hospital Colombo, Puttalam, Sri Lanka"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Iranthi","family":"Kumarasinghe","sequence":"additional","affiliation":[{"name":"Clinical Sciences, General Sir John Kotelawala Defence University Faculty of Medicine, Ratmalana, Sri Lanka"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eranda Diyagama","family":"Gunasekera","sequence":"additional","affiliation":[{"name":"Clinical Sciences, General Sir John Kotelawala Defence University Faculty of Medicine, Ratmalana, Sri Lanka"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2024,11,2]]},"reference":[{"key":"2025082704001363000_17.11.e261053.1","doi-asserted-by":"crossref","first-page":"42","DOI":"10.1016\/S1028-4559(08)60053-4","article-title":"Abdominal wall endometriosis: an overlooked but possibly preventable complication","volume":"47","author":"Teng","year":"2008","journal-title":"Taiwan J Obstet Gynecol"},{"key":"2025082704001363000_17.11.e261053.2","doi-asserted-by":"publisher","DOI":"10.1016\/j.amjsurg.2007.07.035"},{"key":"2025082704001363000_17.11.e261053.3","first-page":"223","article-title":"Scar endometriosis, a tricky diagnosis.
