Primary Diffuse B-cell Lymphoma of Uterine Cervix: A Case Report

Primary diffuse large B-cell lymphoma (DLBCL) of the female genital tract is a rare case. It is hard to diagnose DLBCL of the uterine cervix before surgery because it is often misdiagnosed as cervical myoma or cervical squamous cell carcinoma. Here, we report a case of cervical DLBCL misdiagnosed as a cervical myoma. A 48-year-old premenopausal woman was referred to the gynecology department due to abnormal uterine bleeding with a normal Papanicolaou smear. The initial diagnosis according to ultrasound and computed tomography was a cervical myoma. She had undergone a hysterectomy with bilateral salpingectomy. The final diagnosis was cervical DLBCL and she was referred to the department of hematology for treatment with Rituximab combined chemotherapy. After six courses of chemotherapy, complete remission was reached. At a 2-year follow-up, the patient is alive without interval change.
