Primary female genital system lymphoma complicated by a recurrent mucinous borderline ovarian tumor: a case report and review of the literature

Abstract

Abstract Background Primary female genital system lymphoma (PFGSL) is an infrequent entity. All genital organs may be affected, and most PFGSLs are localized to the cervix, uterine body, and ovaries. The clinical manifestations are nonspecific, which complicates a timely diagnosis. We report an unexpected case of PFGSL and discuss the disease characteristics by reviewing the literature. Case presentation A 48-year-old G3/P2 woman presented to the Department of Gynecology with a physical examination. Ultrasound examination and CT revealed pelvic masses. The woman underwent surgical treatment because of the pelvic masses and underwent a hysterectomy for a recurrent mucinous borderline ovarian tumor. However, the results of the postoperative pathological examination showed diffuse large B-cell lymphoma of the endometrium. After four courses of chemotherapy, the woman was in good condition. The clinical manifestations were nonspecific, which made a timely diagnosis complex. Conclusion This case highlights the importance of the difficulty in detecting early PFGSL early and how easily nonspecific manifestations can be ignored. It may lead to missing the best time for early treatment.
