We herein report a rare case of a 29-year-old female, presented with a history of watering in the right eye associated with a rapidly progressive mass for 4 months near the medial canthus. Further clinical examination revealed firm, non-tender mass occupying the lacrimal sac fossa extending above the medial canthus. The systemic examination was unremarkable, with a palpable right submandibular lymph node palpable. Contrast-enhanced computerized tomography (CECT) orbit revealed a well-defined mass at the medial canthus extending into the osseous nasolacrimal canal. An excision biopsy was performed, and histopathology revealed a poorly differentiated sebaceous carcinoma of the lacrimal sac. The oncologist advised CECT chest, face, and neck post-surgery, which revealed malignant neoplastic changes at the right lacrimal sac region and lacrimal duct with metastasis at right nodes I b, II, V, and left nodes I b and II. Five-month follow-up showed no signs of recurrence. <\/jats:p>","DOI":"10.1177\/2050313x241271787","type":"journal-article","created":{"date-parts":[[2024,11,16]],"date-time":"2024-11-16T09:44:28Z","timestamp":1731750268000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Poorly differentiated sebaceous carcinoma of the lacrimal sac in a young adult: A case report"],"prefix":"10.1177","volume":"12","author":[{"given":"Sandeep","family":"Pal","sequence":"first","affiliation":[{"name":"Department of Orbit and Oculoplasty, Sadguru Netra Chikitsalaya, Chitrakoot, Uttar Pradesh, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4452-6971","authenticated-orcid":false,"given":"Narendra","family":"Patidar","sequence":"additional","affiliation":[{"name":"Department of Orbit and Oculoplasty, Sadguru Netra Chikitsalaya, Chitrakoot, Uttar Pradesh, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ashik","family":"R","sequence":"additional","affiliation":[{"name":"Department of Orbit and Oculoplasty, Sadguru Netra Chikitsalaya, Chitrakoot, Uttar Pradesh, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Poonam","family":"Arora Agrawal","sequence":"additional","affiliation":[{"name":"Department of Pathology, Central Laboratory, Indore, Madhya Pradesh, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dev Kumar","family":"Tekam","sequence":"additional","affiliation":[{"name":"Department of Orbit and Oculoplasty, Sadguru Netra Chikitsalaya, Chitrakoot, Uttar Pradesh, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2024,11,16]]},"reference":[{"key":"bibr1-2050313X241271787","doi-asserted-by":"publisher","DOI":"10.1080\/01676830.2020.1769684"},{"key":"bibr2-2050313X241271787","doi-asserted-by":"publisher","DOI":"10.4103\/meajo.MEAJO_275_19"},{"volume-title":"Principles and practice of ophthalmology","year":"2008","author":"Jakobiec FA","key":"bibr3-2050313X241271787"},{"key":"bibr4-2050313X241271787","doi-asserted-by":"publisher","DOI":"10.1016\/j.survophthal.2004.12.008"},{"key":"bibr5-2050313X241271787","doi-asserted-by":"publisher","DOI":"10.1097\/IOP.0b013e31829f3a73"},{"issue":"6","key":"bibr6-2050313X241271787","first-page":"499","volume":"43","author":"Bi Y-W","year":"2007","journal-title":"Zhonghua Yan Ke Za Zhi"},{"key":"bibr7-2050313X241271787","doi-asserted-by":"publisher","DOI":"10.3109\/01676830903071182"},{"key":"bibr8-2050313X241271787","doi-asserted-by":"publisher","DOI":"10.1097\/IOP.0000000000001386"},{"key":"bibr9-2050313X241271787","doi-asserted-by":"publisher","DOI":"10.1080\/01676830.2019.1700282"},{"key":"bibr10-2050313X241271787","doi-asserted-by":"publisher","DOI":"10.1097\/00002341-198912000-00001"},{"key":"bibr11-2050313X241271787","doi-asserted-by":"publisher","DOI":"10.1016\/S0161-6420(92)31988-8"}],"container-title":["SAGE Open Medical Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/2050313X241271787","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/2050313X241271787","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/2050313X241271787","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,3,2]],"date-time":"2025-03-02T22:42:15Z","timestamp":1740955335000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/2050313X241271787"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2024,1]]},"references-count":11,"alternative-id":["10.1177\/2050313X241271787"],"URL":"https:\/\/doi.org\/10.1177\/2050313x241271787","relation":{},"ISSN":["2050-313X","2050-313X"],"issn-type":[{"type":"print","value":"2050-313X"},{"type":"electronic","value":"2050-313X"}],"subject":[],"published":{"date-parts":[[2024,1]]},"article-number":"2050313X241271787"}}
