The patient presented with non\u2010bloody diarrhea, abdominal pain, and weight loss. A colonoscopy revealed a cecal polypoid mass that required laparoscopic surgery. The residual appendix was dilated with myxoglobulosis and histopathology confirmed the diagnosis of a low\u2010grade appendiceal mucinous neoplasm staged pT3Nx. The potential risk of pseudomyxoma peritonei is a serious complication of these tumors. Surveillance plans include computed tomography abdomen and pelvis, and tumor markers every 6 months for the next 2 years. This case highlights the importance of considering appendiceal malignancy in patients with abdominal pain and weight loss, despite the rarity of the disease. It also emphasizes the need for careful monitoring due to the possible complications associated with these tumors. Treatment and prognosis for appendiceal neoplasms depend on the histopathologic characteristics, tumor\u2010nodes\u2010metastasis stage, tumor grade, and presence of peritoneal disease.<\/jats:p>","DOI":"10.1002\/jpr3.12017","type":"journal-article","created":{"date-parts":[[2023,12,27]],"date-time":"2023-12-27T11:59:06Z","timestamp":1703678346000},"page":"66-69","source":"Crossref","is-referenced-by-count":2,"title":["Appendiceal
