It is often misdiagnosed as eczema, leukoplakia, squamous cell carcinoma, Bowen\u2019s disease, lichen planus, or condylomata acuminata. We report a case of a 63\u2010year\u2010old male who presented to the emergency room (ER) for evaluation of an anal mass that had persisted over 6 months. The patient was found to have a rectal adenocarcinoma with pagetoid spread and underwent neoadjuvant chemoradiation with symptom improvement. However, the patient declined further chemotherapy and the planned abdominal perineal resection with reconstruction, as it would require a permanent colostomy.<\/jats:p>","DOI":"10.1155\/2024\/4952952","type":"journal-article","created":{"date-parts":[[2024,10,21]],"date-time":"2024-10-21T11:20:11Z","timestamp":1729509611000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Rectal Adenocarcinoma With Pagetoid Spread: A Novel Entity"],"prefix":"10.1155","volume":"2024","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2772-6085","authenticated-orcid":false,"given":"Lefika","family":"Bathobakae","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pasha","family":"Shenasan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Aakash","family":"Trivedi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ruhin","family":"Yuridullah","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sohail","family":"Qayyum","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Abraham","family":"El-Sedfy","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2024,10,21]]},"reference":[{"key":"e_1_2_11_1_2","doi-asserted-by":"publisher","DOI":"10.1159\/000256382"},{"key":"e_1_2_11_2_2","doi-asserted-by":"publisher","DOI":"10.1093\/jjco\/28.5.347"},{"key":"e_1_2_11_3_2","doi-asserted-by":"publisher","DOI":"10.1186\/1752-1947-7-162"},{"key":"e_1_2_11_4_2","doi-asserted-by":"publisher","DOI":"10.3393\/ac.2014.30.5.241"},{"key":"e_1_2_11_5_2","doi-asserted-by":"publisher","DOI":"10.1136\/pgmj.53.626.768"},{"key":"e_1_2_11_6_2","doi-asserted-by":"publisher","DOI":"10.1136\/bcr-2013-200504"},{"key":"e_1_2_11_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.amsu.2016.06.012"},{"key":"e_1_2_11_8_2","doi-asserted-by":"publisher","DOI":"10.1186\/s40792-018-0469-5"},{"key":"e_1_2_11_9_2","doi-asserted-by":"publisher","DOI":"10.1177\/014107689709001217"},{"key":"e_1_2_11_10_2","doi-asserted-by":"publisher","DOI":"10.1159\/000363177"},{"key":"e_1_2_11_11_2","doi-asserted-by":"publisher","DOI":"10.1186\/s13000-020-00952-w"},{"key":"e_1_2_11_12_2","doi-asserted-by":"publisher","DOI":"10.1007\/s12262-017-1590-6"},{"key":"e_1_2_11_13_2","doi-asserted-by":"publisher","DOI":"10.1159\/000506832"},{"key":"e_1_2_11_14_2","doi-asserted-by":"publisher","DOI":"10.3390\/cancers15235665"}],"container-title":["Case Reports in Gastrointestinal Medicine"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1155\/2024\/4952952","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,10,21]],"date-time":"2024-10-21T11:20:15Z","timestamp":1729509615000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1155\/2024\/4952952"}},"subtitle":[],"editor":[{"given":"Hirotada","family":"Akiho","sequence":"additional","affiliation":[],"role":[{"role":"editor","vocabulary":"crossref"}]}],"short-title":[],"issued":{"date-parts":[[2024,1]]},"references-count":14,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2024,1]]}},"alternative-id":["10.1155\/2024\/4952952"],"URL":"https:\/\/doi.org\/10.1155\/2024\/4952952","archive":["Portico"],"relation":{},"ISSN":["2090-6528","2090-6536"],"issn-type":[{"value":"2090-6528","type":"print"},{"value":"2090-6536","type":"electronic"}],"subject":[],"published":{"date-parts":[[2024,1]]},"assertion":[{"value":"2024-05-04","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2024-09-21","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2024-10-21","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}],"article-number":"4952952"}}
