title: Diffuse large B-cell non-Hodgkin's lymphoma presenting as a vaginal mass in a patient with a history of intestinal mucosa-associated lymphoid tissue (MALT) lymphoma.
abstract: Vaginal involvement in non-Hodgkin's lymphoma is uncommon and is often secondary to disseminated disease. Primary disease at this site is quite rare. We present here an unusual case of a patient who developed a diffuse large B-cell lymphoma presenting as a vaginal mass after having been treated for primary intestinal mucosa-associated lymphoid tissue (MALT) lymphoma 4 years earlier. Combined chemotherapy and radiation therapy for the intestinal MALT lymphoma produced complete remission that lasted for 2 years. Chemotherapy given for the diffuse large B-cell lymphoma with secondary vaginal involvement produced a second complete remission. The second remission was consolidated with high-dose chemotherapy and autologous bone marrow transplantation. Although the patient died from complications related to the transplant procedure, the disease was in complete remission at the time of her death. Given the rarity of primary intestinal MALT lymphoma and primary vaginal lymphoma, no standard treatment has been established. Treatment options have included chemotherapy, radiation therapy, or surgery, given alone or in combination.
