The most common histological subtype of PLFGT is diffuse large B-cell lymphoma (DLBCL), which most commonly arises from the ovary, cervix, uterus or vagina. It is rarer still for DLBCL to arise from the fallopian tube, and therefore, we present the second case ever reported. A woman in her 30s presented with abdominal pain and a pelvic mass on CT. The mass was laparoscopically excised, which allowed the histological diagnosis to be made, and the patient was subsequently treated with chemotherapy. This report aims to contribute to existing knowledge of this rare condition because, although unusual, PLFGT is a potential diagnosis to consider when managing pelvic masses.<\/jats:p>","DOI":"10.1136\/bcr-2025-269103","type":"journal-article","created":{"date-parts":[[2026,1,29]],"date-time":"2026-01-29T14:40:28Z","timestamp":1769697628000},"page":"e269103","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Rare diagnosis: the second documented report of primary diffuse large B-cell lymphoma of the fallopian tube"],"prefix":"10.1136","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1561-2523","authenticated-orcid":false,"given":"Emma Jacqueline","family":"Lane","sequence":"first","affiliation":[{"name":"Obstetrics and Gynaecology, Bundaberg Base Hospital, Queensland Health, Brisbane, Queensland, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sven","family":"Watmore","sequence":"additional","affiliation":[{"name":"Obstetrics and Gynaecology, Bundaberg Base Hospital, Queensland Health, Brisbane, Queensland, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2026,1,29]]},"reference":[{"key":"2026012906401390000_19.1.e269103.1","unstructured":"Australian Institute of Health and Welfare .
