Cases associated with dysplastic or neoplastic epithelium can rupture and disseminate within the abdominopelvic cavity. Similar lesions in other parts of the colon are exceedingly rare, with only 16 colonic mucoceles having been reported. The first case of a colonic mucinous neoplasm with dysplasia resembling a low-grade appendiceal mucinous neoplasm involving rectal stump was described in 2016. Here, we present the second such case arising in the rectal stump, identified in a 44-year-old male with extensive surgical history. Microscopic examination revealed low-grade dysplastic epithelium lining the cyst and mucin dissecting into the stroma, without evidence of rupture or extramural mucin. The patient was followed for 16 months without recurrence or peritoneal disease. The exact etiology and outcome of these rare lesions remain unknown, requiring close follow-up.<\/jats:p>","DOI":"10.4132\/jptm.2024.12.27","type":"journal-article","created":{"date-parts":[[2025,2,26]],"date-time":"2025-02-26T05:48:32Z","timestamp":1740548912000},"page":"139-146","update-policy":"https:\/\/doi.org\/10.4132\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Mucocele of the rectal stump: mucinous cystic neoplasm with low-grade dysplasia simulating low-grade appendiceal mucinous neoplasm"],"prefix":"10.4132","volume":"59","author":[{"ORCID":"https:\/\/orcid.org\/0009-0000-4737-5107","authenticated-orcid":true,"given":"Hasan Basri","family":"Aydin","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-7303-2484","authenticated-orcid":true,"given":"Maria","family":"Faraz","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-1033-6444","authenticated-orcid":true,"given":"A.
