A rare case report of primary uterine and vaginal lymphoma in the elderly

Abstract

Uterine lymphoma is rare and usually occurs in middle-aged women. The clinical symptoms lack any specific characteristics. Imaging characteristics usually include uterine enlargement with density and uniform signal soft tissue masses. Magnetic resonance T2 weighted imaging, enhanced scanning, diffusion weighted imaging and apparent diffusion coefficient values have certain characteristics. The gold standard for diagnosis remains a pathological examination of a biopsy specimen. The special feature of this current case was that the uterine lymphoma occurred in an 83-year-old female patient that presented with a pelvic mass for more than 1 month. Based on the imaging findings, a primary uterine lymphoma was considered, but her advanced age of onset did not match the disease. After pathological confirmation, the patient was diagnosed with uterine lymphoma and she received eight cycles of R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, prednisolone) plus local radiotherapy for the large masses. The patients achieved good results. Follow-up enhanced computed tomography imaging showed that the uterine volume had significantly reduced compared with before treatment. The diagnosis of elderly patients with uterine lymphoma can provide a more accurate plan for subsequent treatment.
