We report the case of a 48\u2010year\u2010old man in whom a retrorectal mass was incidentally detected on abdominal and pelvic computed tomography. Magnetic resonance imaging demonstrated a cystic lesion measuring 32\u2009\u00d7\u200912\u2009\u00d7\u200920\u2009mm, with low signal intensity on T1\u2010weighted and high signal intensity on T2\u2010weighted images. Given the difficulty of establishing a definitive diagnosis and the potential risk of infection or tumor seeding with biopsy, primary surgical resection was selected. A combined laparoscopic transabdominal and trans\u2010sacral approach enabled precise dissection under enhanced visualization of the pelvic anatomy, ensuring safe and complete tumor excision. The patient's postoperative course was uneventful, and he remained recurrence\u2010free at the 1\u2010year follow\u2010up. This case highlights the pivotal role of laparoscopy in facilitating the safe resection of retrorectal tumors.<\/jats:p>","DOI":"10.1111\/ases.70068","type":"journal-article","created":{"date-parts":[[2025,4,24]],"date-time":"2025-04-24T01:47:28Z","timestamp":1745459248000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["A Case of Epidermal Cyst in the Retrorectum Safely Resected by a Combined Laparoscopic Approach"],"prefix":"10.1111","volume":"18","author":[{"given":"Yusuke","family":"Tanaka","sequence":"first","affiliation":[{"name":"Department of Gastroenterological Surgery Osaka Metropolitan University Graduate School of Medicine  Osaka Japan"},{"name":"Department of Gastroenterological Surgery Tsukazaki Hospital  Himeji Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5234-4030","authenticated-orcid":false,"given":"Hiroaki","family":"Kasashima","sequence":"additional","affiliation":[{"name":"Department of Gastroenterological Surgery Osaka Metropolitan University Graduate School of Medicine  Osaka Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tatsunari","family":"Fukuoka","sequence":"additional","affiliation":[{"name":"Department of Gastroenterological Surgery Osaka Metropolitan University Graduate School of Medicine  Osaka Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ken","family":"Yonemitsu","sequence":"additional","affiliation":[{"name":"Department of Gastroenterological Surgery Osaka Metropolitan University Graduate School of Medicine  Osaka Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuki","family":"Seki","sequence":"additional","affiliation":[{"name":"Department of Gastroenterological Surgery Osaka Metropolitan University Graduate School of Medicine  Osaka Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kenji","family":"Kuroda","sequence":"additional","affiliation":[{"name":"Department of Gastroenterological Surgery Osaka Metropolitan University Graduate School of Medicine  Osaka Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuichiro","family":"Miki","sequence":"additional","affiliation":[{"name":"Department of Gastroenterological Surgery Osaka Metropolitan University Graduate School of Medicine  Osaka Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mami","family":"Yoshii","sequence":"additional","affiliation":[{"name":"Department of Gastroenterological Surgery Osaka Metropolitan University Graduate School of Medicine  Osaka Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tatsuro","family":"Tamura","sequence":"additional","affiliation":[{"name":"Department of Gastroenterological Surgery Osaka Metropolitan University Graduate School of Medicine  Osaka Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masatsune","family":"Shibutani","sequence":"additional","affiliation":[{"name":"Department of Gastroenterological Surgery Osaka Metropolitan University Graduate School of Medicine  Osaka Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takahiro","family":"Toyokawa","sequence":"additional","affiliation":[{"name":"Department of Gastroenterological Surgery Osaka Metropolitan University Graduate School of Medicine  Osaka Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shigeru","family":"Ree","sequence":"additional","affiliation":[{"name":"Department of Gastroenterological Surgery Osaka Metropolitan University Graduate School of Medicine  Osaka Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kiyoshi","family":"Maeda","sequence":"additional","affiliation":[{"name":"Department of Gastroenterological Surgery Osaka Metropolitan University Graduate School of Medicine  Osaka Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,4,23]]},"reference":[{"key":"e_1_2_11_2_1","first-page":"449","article-title":"Surgical Management of Precoccygeal Cysts","volume":"115","author":"Spencer R.
