Med."],"abstract":"<jats:p>Inguinal dermoid cysts are exceedingly rare, with most reported cases arising from the spermatic cord in male patients or the round ligament in female patients. We report a rare case of a inguinal dermoid cyst in a young woman presenting as an irreducible inguinal mass with gradually increasing local discomfort. Preoperative imaging suggested a benign but nonspecific cystic lesion, extending from the preperitoneal plane to the layer beneath the external oblique aponeurosis. The lesion was excised using a combined laparoscopic and open approach. Intraoperative cyst rupture released sebaceous material and hair, prompting reconstruction using a McVay tissue repair. Combined intraoperative and histopathological findings supported the diagnosis of dermoid cyst. This case highlights the need for a broad differential diagnosis of atypical irreducible inguinal masses and carefully integrating clinical, imaging, and intraoperative findings to facilitate accurate diagnosis and guide appropriate surgical management.<\/jats:p>","DOI":"10.3389\/fmed.2026.1857872","type":"journal-article","created":{"date-parts":[[2026,6,12]],"date-time":"2026-06-12T04:42:20Z","timestamp":1781239340000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Inguinal dermoid cyst in Hesselbach\u2019s triangle with diagnostic and surgical decision-making challenges: a case report"],"prefix":"10.3389","volume":"13","author":[{"given":"Tian","family":"Kuang","sequence":"first","affiliation":[{"name":"Department of Gastrointestinal Surgery, Renji Hospital, School of Medicine, Shanghai Jiaotong University","place":["Shanghai, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xin","family":"Qian","sequence":"additional","affiliation":[{"name":"Department of Vascular Surgery, Renji Hospital, School of Medicine, Shanghai Jiaotong University","place":["Shanghai, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yanying","family":"Shen","sequence":"additional","affiliation":[{"name":"Department of Pathology, Renji Hospital, School of Medicine, Shanghai Jiaotong University","place":["Shanghai, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Danping","family":"Shen","sequence":"additional","affiliation":[{"name":"Department of Gastrointestinal Surgery, Renji Hospital, School of Medicine, Shanghai Jiaotong University","place":["Shanghai, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2026,6,12]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","first-page":"343","DOI":"10.1007\/s10029-009-0529-7","article-title":"European hernia society guidelines on the treatment of inguinal hernia in adult patients","volume":"13","author":"Simons","year":"2009","journal-title":"Hernia"},{"key":"ref2","doi-asserted-by":"publisher","first-page":"148","DOI":"10.2214\/ajr.110.1.148","article-title":"Epidermoid and dermoid sequestration cysts","volume":"110","author":"Pear","year":"1970","journal-title":"Am J Roentgenol Radium Therapy, Nucl Med"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.3390\/diagnostics15060712","article-title":"Ruptured intracranial dermoid cyst with fat dissemination: a clinical case mimicking an epidermoid cyst and review of the literature","volume":"15","author":"Verzemnieks","year":"2025","journal-title":"Diagnostics (Basel)"},{"key":"ref4","doi-asserted-by":"publisher","first-page":"1227","DOI":"10.1007\/s00701-008-0152-x","article-title":"Intracranial dermoid cysts: variations of radiological and clinical features","volume":"150","author":"Orakcioglu","year":"2008","journal-title":"Acta Neurochir"},{"key":"ref5","doi-asserted-by":"publisher","first-page":"E29","DOI":"10.5489\/cuaj.1136","article-title":"Dermoid cyst of the spermatic cord: a rare cause of benign inguinal lump","volume":"3","author":"Aslam","year":"2009","journal-title":"Can Urol Assoc J"},{"key":"ref6","doi-asserted-by":"publisher","first-page":"678","DOI":"10.1308\/rcsann.2022.0102","article-title":"A large dermoid cyst of the spermatic cord","volume":"105","author":"Pang","year":"2023","journal-title":"Ann R Coll Surg Engl"},{"key":"ref7","doi-asserted-by":"publisher","first-page":"321","DOI":"10.1007\/s10029-009-0542-x","article-title":"Large dermoid cyst of the spermatic cord presenting as an incarcerated hernia: a rare presentation and literature review","volume":"14","author":"Salemis","year":"2010","journal-title":"Hernia"},{"key":"ref8","first-page":"249","article-title":"Inguinal dermoid cyst of the round ligament.
