An unusual cause of postmenopausal bleeding.

Background: Non-Hodgkin lymphoma usually presents with lymphadenopathy, fever, night sweats, and weight loss. Postmenopausal vaginal bleeding is a cardinal symptom of carcinoma of the endometrium or cervix but not one of non-Hodgkin lymphoma. Clinical awareness of this unusual mode of presentation is important.

Case: We report a case of non-Hodgkin lymphoma in a 60-year-old woman, who presented primarily with postmenopausal bleeding. Clinical examination revealed a "thickened" area on the posterior vaginal wall. Repeated vaginal biopsies showed fibrosis and inflammatory tissue only. Immunohistochemistry revealed non-Hodgkin lymphoma. This case highlights the diagnostic challenges such a complex case presents.

Conclusion: This case not only represents a case of non-Hodgkin lymphoma with genital involvement but also highlights the importance of diagnosis and management of such complex cases.
