Multiple biopsies were negative for malignancy and CT\/MRI scans showed no malignant mass. A provisional diagnosis of prolapsed haemorrhoids was made and the mass was treated with sugar and charcoal dressings. There was a dramatic resolution of the mass with this treatment and the patient was discharged 1 month post-admission. The patient then underwent an elective haemorrhoidectomy by which time the mass had decreased to a perianal skin tag. The only clues in this case were the acute presentation of the mass, the fact that the mass had appeared post-defecation and that the patient had been diagnosed with haemorrhoids 2 years previously on colonoscopy. This case highlights the importance of evaluating all investigations and considering all differential diagnoses before embarking on definitive management.<\/jats:p>","DOI":"10.1136\/bcr.01.2012.5667","type":"journal-article","created":{"date-parts":[[2012,7,17]],"date-time":"2012-07-17T10:48:08Z","timestamp":1342522088000},"page":"bcr0120125667","source":"Crossref","is-referenced-by-count":0,"title":["Obstructive perianal lesion in a 75-year-old man"],"prefix":"10.1136","volume":"2012","author":[{"given":"Rudra Krishna","family":"Maitra","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Thomas","family":"Pinkney","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sriram","family":"Subramonia","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Austin G","family":"Acheson","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2012,7,16]]},"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr.01.2012.5667","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,28]],"date-time":"2025-08-28T12:29:38Z","timestamp":1756384178000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr.01.2012.5667"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2012,7,16]]},"references-count":0,"alternative-id":["10.1136\/bcr.01.2012.5667"],"URL":"https:\/\/doi.org\/10.1136\/bcr.01.2012.5667","relation":{},"ISSN":["1757-790X"],"issn-type":[{"type":"electronic","value":"1757-790X"}],"subject":[],"published":{"date-parts":[[2012,7,16]]}}}
