Malignant lymphoma of the uterine cervix presumptively diagnosed by Pap smear: A case report.

Malignant lymphoma of the uterine cervix is exceedingly rare and is difficult to diagnose by cervical cytology. The current study presents a case of malignant lymphoma of the uterine cervix that was presumptively diagnosed by cervical cancer screening in which the patient had no clinical symptoms. The anterior lip of the uterine cervix was occupied by a macroscopic hemorrhagic tumor. The obtained tumor cells exhibited typical cytological features of malignant lymphoma and were positive for CD20. The final diagnosis was diffuse large B cell lymphoma of the uterine cervix, stage IIEA (Ann Arbor classification). The patient received 6 courses of R-CHOP chemotherapy and achieved complete remission. Despite its rarity, the possibility of malignant lymphoma should be considered while screening for cervical cancers using Pap smears. The Pap test screening may be useful for the early diagnosis of malignant lymphoma of the uterine cervix in certain cases. By reaching a rapid and accurate diagnosis, immediate treatment may be initiated and surgery may be avoided.
