Primary appendiceal lymphoma is extremely rare, with symptoms usually mimicking those of acute appendicitis. Here, we present a rare case of primary appendiceal non-Hodgkin lymphoma with ileocecal valve involvement and coexistence of Schistosoma eggs. The patient was initially diagnosed with acute perforation appendicitis. Following laparoscopic appendectomy, the patient developed an enterocutaneous fistula, which was addressed surgically after the failure of conservative management. Adjuvant chemotherapy with R-CHOP regimen was further planned for the patient.<\/jats:p>","DOI":"10.1093\/jscr\/rjaf274","type":"journal-article","created":{"date-parts":[[2025,5,8]],"date-time":"2025-05-08T04:17:22Z","timestamp":1746677842000},"source":"Crossref","is-referenced-by-count":0,"title":["Rare
