title: [Primary lymphoma of the vagina].
abstract: Primary vaginal non-Hodgkin's lymphomas (NHL) are rare, and are clinically difficult to differentiate from inflammatory diseases or vaginal cancer. Here, we present such a case in a 74-year-old woman complaining of fever and difficulty with urination. Pelvic examination revealed a tumor involving most of the vaginal wall, and pelvic MRI demonstrated vaginal wall thickening. A biopsy of this lesion confirmed NHL (diffuse large B-cell lymphoma), and the patient was admitted. Abdominal CT and MRI detected a vaginal tumor, and Ga scintigraphy confirmed accumulation in the pelvis, but no abnormalities were seen in other areas. Therefore, the patient was diagnosed as having NHL at clinical stage IB with low-intermediate risk (international prognosis index) (LDH 1,309 IU/L). The patient underwent three courses of CHOP therapy followed by radiotherapy, and complete remission was achieved. Primary vaginal NHL often affects women younger than 50 years of age, and abnormal hemorrhage is the initial symptom in many cases. There have been a number of reports of long-term survival following appropriate early chemotherapy and radiation therapy, suggesting that early diagnosis and treatment based on vaginal biopsy findings greatly influence the prognosis.
