ABSTRACT

Conclusion:

Lymphoma of genital tract should be kept in mind in the case of difficulty to clarify the differential diagnosis of uterine bleeding or mass. Especially if uterine lymphoma infiltrated to the uterine wall deeply, preoperative histological analysis could not reveal the real pathology.

Case report:

A-62 years old woman presented with postmenoposal bleeding. All the imaging studies [transvaginal ultrasonography (USG), Doppler USG, magnetic resonance imaging (MRI)] showed only enlarged uterus with a mass lesion orginated from uterine wall. The histopathologic analysis of fractionated cervical and uterine curettage were not diagnostic for postmenoposal bleeding and uterine mass lesion. To clarify the diagnosis, total abdominal hysterectomy (TAH), bilateral salpingooferectomy (BSO), peritoneal cytology sampling and frozen were carried out. While the frozen was reported in favour of malign pathology, the operation was continued with bilateral pelvic and paraaortic lymph node dissection (BPPLND) and omentectomy.
Routine pathology demonstrated diffuse large B cell lymphoma infiltrating myometrial wall. Bone marrow examination was normal. Flourodeoxyglucose positron emission tomography / computered tomography (FDG-PET/CT) showed no FDG-avid area in favour of lymphoma on whole body scan. She was considered as primary uterine lymphoma and received rituximab, cyclophosphamide,adriamycin, vincristine ve prednisolone (R-CHOP) chemotherapy by hematology clinical follow up. She remains in complete clinical and radiological remission 6 months after the treatment.

Background:

Lymphoma of primary genital tract is uncommon. The similarity of its symptoms (vaginal bleeding, pelvic pain,etc..) with other genital system diseases, presence of nonspesific symptoms on histologic and imaging examinations may make the diagnosis delayed and may cause overtreatment.
