Low-grade appendiceal mucinous neoplasms (LAMNs) make up a small portion of these neoplasms. We present a rare case of a patient with a slow-growing LAMN causing urinary retention and constipation. The mass was initially found incidentally 25\u00a0years prior, but the patient declined further workup since he was asymptomatic at that time. The patient experienced progressively worsening abdominal discomfort related to urinary retention and difficulty in evacuating his bowels. Imaging identified a large abdominal mass (19.3\u2009\u00d7\u20098.7\u2009\u00d7\u200913.5\u00a0cm). The mass was surgically resected. Pathology was consistent with a LAMN. In general, an incidental finding of an abdominal mass should be further investigated regardless of symptomology. Patients should be educated about the potential of malignancy and the need for a major abdominal surgery in the future if they choose not to have a mass further evaluated.<\/jats:p>","DOI":"10.1093\/jscr\/rjac111","type":"journal-article","created":{"date-parts":[[2022,3,10]],"date-time":"2022-03-10T12:08:37Z","timestamp":1646914117000},"source":"Crossref","is-referenced-by-count":1,"title":["A
