We report a 42-year-old female patient who presented to a tertiary care hospital in Muscat, Oman, in 2023 due to a 7-year history of chronic diarrhoea associated with progressive abdominal distension over the past 2 years. Her assessment was significant for ascites. No neoplastic lesions were found on the upper and lower gastrointestinal scopes. A diagnostic ascitic tapping revealed a free flow of gel-like thick, yellowish fluid. A diagnostic laparoscopy showed a perforated appendicular mass with diffuse peritoneal nodules and mucin ascites. Subsequently, the patient underwent cytoreductive surgery with heated intraperitoneal chemotherapy. On follow-up, the patient's abdominal distension and diarrhoea had resolved. This case reports an unusual presentation of a very rare disorder and highlights the challenge of diagnosing PMP.<\/jats:p>","DOI":"10.18295\/2075-0528.2822","type":"journal-article","created":{"date-parts":[[2025,5,3]],"date-time":"2025-05-03T05:39:46Z","timestamp":1746250786000},"page":"276-281","source":"Crossref","is-referenced-by-count":1,"title":["Pseudomyxoma Peritonei: &lt;em&gt;Exploring an unusual clinical presentation \u2013 A case report&lt;\/em&gt;"],"prefix":"10.18295","volume":"25","author":[{"given":"Mallak Al","family":"Naabi","sequence":"first","affiliation":[{"name":"Internal Medicine Residency Program, Oman Medical Specialty Board, Muscat, Oman"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Salim Al","family":"Busaidi","sequence":"additional","affiliation":[{"name":"Department of Medicine, Sultan Qaboos University Hospital, University Medical City, Muscat, Oman"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Amwaj Al","family":"Shahi","sequence":"additional","affiliation":[{"name":"Internal Medicine Residency Program, Oman Medical Specialty Board, Muscat, Oman"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maha Al","family":"Shaibi","sequence":"additional","affiliation":[{"name":"Department of Surgery, Sultan Qaboos Comprehensive Cancer Care and Research Centre, University Medical City, Muscat, Oman"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Khalid Al","family":"Shamousi","sequence":"additional","affiliation":[{"name":"Department of Medicine, Sultan Qaboos University Hospital, University Medical City, Muscat, Oman"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Abdullah Al","family":"Alawi","sequence":"additional","affiliation":[{"name":"Internal Medicine Residency Program, Oman Medical Specialty Board, Muscat, Oman AND Department of Medicine, Sultan Qaboos University Hospital, University Medical City, Muscat, Oman"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohammed Al","family":"Hosni","sequence":"additional","affiliation":[{"name":"Department of Surgery, Sultan Qaboos Comprehensive Cancer Care and Research Centre, University Medical City, Muscat, Oman"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"7681","published-online":{"date-parts":[[2025,5,2]]},"container-title":["Sultan Qaboos University Medical Journal"],"original-title":[],"language":"en","deposited":{"date-parts":[[2026,10,27]],"date-time":"2026-10-27T14:24:46Z","timestamp":1793111086000},"score":1,"resource":{"primary":{"URL":"https:\/\/mjournal.squ.edu.om\/home\/vol25\/iss1\/37"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,5,2]]},"references-count":0,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2025,5,2]]}},"URL":"https:\/\/doi.org\/10.18295\/2075-0528.2822","relation":{},"ISSN":["2075-0528"],"issn-type":[{"value":"2075-0528","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,5,2]]}}}
