Introduction/Background Primary Malignant lymphoma of the uterine cervix can be misdiagnosed due to its rarity and distinct clinical presentation. We introduce a case of PCL which was misdiagnosed as an ovarian cyst on ultrasonography.

Methodology A 31-year-old woman with chief complain of abnormal uterine bleeding was referred as a suspicious malignant ovarian mass on sonography. The evaluation demonstrated large cervical mass as clinical staging allocated her to stage IB 2 disease of uterine cervix.

Results After the confirmed diagnosis of non-Hodgkin B-cell lymphoma of cervix, rituximab was added to the systemic CHOP (cyclophosphamide, adriamycin, vincristine, and prednisolone) chemotherapy regimen. Now, the patient is disease-free with no signs of recurrence.

Conclusion In patients with vaginal bleeding and cervical tumor, it is important to consider the possibility of primary cervical lymphoma in the differential diagnosis of cervical cancer due to different treatment and prognosis.
