There are currently no published case reports of low-grade appendiceal mucinous neoplasms (LAMNs) mimicking perforated diverticulitis. LAMNs are a heterogenous group of tumours, with no consensus treatment algorithm based on stage and histology. In this case report, we discuss a patient who presented emergently with generalized peritonism, with a diagnosis of perforated diverticulitis made on computed tomography scan. At laparotomy, a perforated appendix was identified, with histopathology identifying a perforated LAMN. This case highlights the importance of considering this rare but increasing incidence tumour when operative management is being planned.<\/jats:p>","DOI":"10.1093\/jscr\/rjac014","type":"journal-article","created":{"date-parts":[[2022,1,11]],"date-time":"2022-01-11T12:08:13Z","timestamp":1641902893000},"source":"Crossref","is-referenced-by-count":0,"title":["Low-grade
