title: [Primary diffuse large B-cell lymphoma of the uterine cervix successfully treated with rituximabplus cyclophosphamide, doxorubicin, vincristine, and prednisone chemotherapy-a case report].
abstract: Primary malignant lymphoma of the uterine cervix is a rare disease, and the therapeutic strategy has not been clearly established. A 45-year old woman presented with vaginal bleeding and hypermenorrhea in January 2012. Physical examination revealed a mass in the pelvic cavity approximately the size of a neonate's head. Pelvic magnetic resonance imaging(MRI) showed a solid mass 11 cm in size in the uterine cervix with homogeneous low intensity on T1-weighted images, iso-high intensity on T2-weighted images, and heterogeneous iso-high intensity on gadolinium-diethylenetriaminepentaacetate(Gd- DTPA)-enhanced images. Multiple lymphadenopathy were also detected in the pelvis. The Papanicolaou smear indicated class 5 cervical cytology, and a subsequent histological examination by a punch biopsy of the cervix showed diffuse infiltration of medium- to large-sized mononuclear cells that stained positive for CD20 and CD79a and negative for CD3, CD5, and EBER. Bone marrow biopsy revealed no abnormality. Positron emission tomography-computed tomography(PET-CT)showed strong fluorodeoxyglucose(FDG)accumulation in the uterine cervix mass, and in the pelvic and right inguinal lymphadenopathy. The patient was diagnosed with diffuse large B-cell lymphoma of the uterine cervix, Ann Arbor stage II AE. She was successfully treated with 8 courses of rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone(R-CHOP) chemotherapy, and maintains a complete remission.
