Rare diagnosis: the second documented report of primary diffuse large B-cell lymphoma of the fallopian tube

Article Text Abstract Primary non-Hodgkin’s lymphoma is a highly prevalent haematologic malignancy but contrarily, primary lymphoma of the female genital tract (PLFGT) is extremely rare. 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. - Gynecological cancer - Obstetrics and gynaecology - Cancer - see Oncology - Haematology (incl blood transfusion) Statistics from Altmetric.com Footnotes Contributors The following author was responsible for drafting the text, sourcing and editing clinical images, investigating results, drawing original diagrams and algorithms, and critically revising important intellectual content: EJL.
