Diagnostic concerns include its deceptively benign appearance in some cases and the difficulty in differentiating it from secondary mucinous carcinoma of skin metastasising from a primary source elsewhere. A case of a 75-year-old man is reported who presented with a slowly growing painless mass near the lateral canthus of the right eye for about 2\u2009years. Clinically, a diagnosis of basal cell carcinoma was made whereas histopathology revealed mucinous carcinoma of the skin. The primary source of the tumour could not be found on detailed physical examination and laboratory investigations. Immunohistochemistry, performed later, was consistent with primary cutaneous mucinous carcinoma.<\/jats:p>","DOI":"10.1136\/bcr-2017-222546","type":"journal-article","created":{"date-parts":[[2018,1,19]],"date-time":"2018-01-19T00:25:23Z","timestamp":1516321523000},"page":"bcr-2017-222546","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":10,"title":["Unusual skin mass (primary cutaneous mucinous carcinoma)"],"prefix":"10.1136","volume":"2018","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6873-1024","authenticated-orcid":false,"given":"Hussnain","family":"Javaid","sequence":"first","affiliation":[{"name":"Military Hospital Rawalpindi, Rawalpindi, Pakistan"},{"name":"Queen Alexandra Hospital, Portsmouth, Hampshire, United Kingdom"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Naeem","family":"Raza","sequence":"additional","affiliation":[{"name":"Department of Dermatology, Military Hospital Rawalpindi, Rawalpindi, Pakistan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Urwa","family":"Ejaz","sequence":"additional","affiliation":[{"name":"Army Medical College, Rawalpindi, Pakistan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tariq","family":"Sarfraz","sequence":"additional","affiliation":[{"name":"Department of Pathology, Army Medical College, Rawalpindi, Pakistan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2018,1,18]]},"reference":[{"key":"2025082802455162000_2018.jan18_1.bcr-2017-222546.1","doi-asserted-by":"publisher","DOI":"10.1097\/DAD.0b013e318158d878"},{"key":"2025082802455162000_2018.jan18_1.bcr-2017-222546.2","doi-asserted-by":"crossref","first-page":"380","DOI":"10.1001\/jamadermatol.2013.6006","article-title":"Primary cutaneous mucinous carcinoma: a systematic review and meta-analysis of outcomes after surgery","volume":"150","author":"Kamalpour","year":"2014","journal-title":"JAMA Dermatol"},{"key":"2025082802455162000_2018.jan18_1.bcr-2017-222546.3","doi-asserted-by":"publisher","DOI":"10.1002\/1097-0142(197911)44:5<1757::AID-CNCR2820440533>3.0.CO;2-8"},{"key":"2025082802455162000_2018.jan18_1.bcr-2017-222546.4","first-page":"79","article-title":"Recurrent mucinous carcinoma of skin mimicking primary mucinous carcinoma of parotid gland: a diagnostic pitfall","volume":"45","author":"Laco","year":"2009","journal-title":"Cesk Patol"},{"key":"2025082802455162000_2018.jan18_1.bcr-2017-222546.5","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-0560.2009.01436.x"},{"key":"2025082802455162000_2018.jan18_1.bcr-2017-222546.6","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-0560.2006.00644.x"},{"key":"2025082802455162000_2018.jan18_1.bcr-2017-222546.7","doi-asserted-by":"publisher","DOI":"10.1097\/01.pas.0000159104.02985.6b"},{"key":"2025082802455162000_2018.jan18_1.bcr-2017-222546.8","doi-asserted-by":"crossref","first-page":"82","DOI":"10.4103\/2229-5178.85997","article-title":"Primary cutaneous mucinous carcinoma: a rare entity","volume":"2","author":"Mardi","year":"2011","journal-title":"Indian Dermatol Online J"},{"key":"2025082802455162000_2018.jan18_1.bcr-2017-222546.9","doi-asserted-by":"crossref","first-page":"241","DOI":"10.1016\/j.ijscr.2015.02.006","article-title":"Primary mucinous adenocarcinoma of the scalp: a case report and literature review","volume":"10","author":"Beteddini","year":"2015","journal-title":"Int J Surg Case Rep"},{"key":"2025082802455162000_2018.jan18_1.bcr-2017-222546.10","doi-asserted-by":"publisher","DOI":"10.1001\/archophthalmol.2010.177"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2017-222546","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,28]],"date-time":"2025-08-28T09:45:58Z","timestamp":1756374358000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2017-222546"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2018,1,18]]},"references-count":10,"alternative-id":["10.1136\/bcr-2017-222546"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2017-222546","relation":{},"ISSN":["1757-790X"],"issn-type":[{"value":"1757-790X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2018,1,18]]}}}
