Low-grade appendiceal mucinous neoplasms with bowel obstruction

Background Perforation of low-grade appendiceal mucinous neoplasms (LAMN) is characterized by its potential to spread mucin into peritoneal cavity, giving rise to pseudomyxoma peritonei, commonly treated with cytoreductive surgery and hyperthermic intraperitoneal chemotherapy. Symptoms of intestinal obstruction and appendiceal infection are rare at early stages of the disease, while abdominal distension are observed in the later stages due to mucin spread.
