Presentation is variable but requires prompt recognition to ensure appropriate specialist management due to risk of malignancy.<\/jats:p>\n               <jats:p>A male in his 40s presented with a 1-day history of sudden onset, non-migratory abdominal pain, worse in the right iliac fossa. He had no significant medical history nor known drug allergies. Examination revealed right iliac fossa peritonism and blood tests revealed raised inflammatory markers. CT scan showed a right-sided abdominal collection. Intraoperatively, a diagnostic laparoscopy was performed, which revealed extensive mucin in the abdominal cavity. This was washed out and a laparoscopic appendectomy was performed; histopathology confirmed PMP from the ruptured appendix.<\/jats:p>","DOI":"10.1136\/bcr-2024-260759","type":"journal-article","created":{"date-parts":[[2024,8,23]],"date-time":"2024-08-23T01:06:10Z","timestamp":1724375170000},"page":"e260759","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":1,"title":["Pseudomyxoma peritonei peritonitis"],"prefix":"10.1136","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0009-0004-8279-7005","authenticated-orcid":false,"given":"Pranathi","family":"Yannamani","sequence":"first","affiliation":[{"name":"Wye Valley NHS Trust, Hereford, Herefordshire, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lillian","family":"Chungu","sequence":"additional","affiliation":[{"name":"Wye Valley NHS Trust, Hereford, Herefordshire, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rajesh","family":"Shetty","sequence":"additional","affiliation":[{"name":"Wye Valley NHS Trust, Hereford, Herefordshire, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7933-0472","authenticated-orcid":false,"given":"Bankole","family":"Oyewole","sequence":"additional","affiliation":[{"name":"Wye Valley NHS Trust, Hereford, Herefordshire, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2024,8,22]]},"reference":[{"key":"2025082700372746000_17.8.e260759.1","doi-asserted-by":"crossref","first-page":"511","DOI":"10.1080\/02656736.2017.1310938","article-title":"Pseudomyxoma peritonei: natural history and treatment","volume":"33","author":"Mittal","year":"2017","journal-title":"Int J Hyperthermia"},{"key":"2025082700372746000_17.8.e260759.2","doi-asserted-by":"crossref","first-page":"44","DOI":"10.4251\/wjgo.v2.i1.44","article-title":"Pseudomyxoma peritonei","volume":"2","author":"Bevan","year":"2010","journal-title":"World J Gastrointest Oncol"},{"key":"2025082700372746000_17.8.e260759.3","doi-asserted-by":"crossref","first-page":"252","DOI":"10.1245\/s10434-020-08655-8","article-title":"Estimating the Prevalence of Pseudomyxoma Peritonei in Europe Using a Novel Statistical Method","volume":"28","author":"Patrick-Brown","year":"2021","journal-title":"Ann Surg Oncol"},{"key":"2025082700372746000_17.8.e260759.4","doi-asserted-by":"crossref","unstructured":"Beaumont O , Miller R , Guy R .
