title: [Early relapse in the central nervous system-after achieving complete response in primary vaginal lymphoma].
abstract: A 76-year-old woman presented with vaginal bleeding and discharge in September 2009. She was admitted to our hospital because a tumor of 5 cm in diameter was found in the vagina in a nearby clinic. She was diagnosed with primary vaginal diffuse large B-cell lymphoma (DLBCL) on biopsy of the tumor because CT, MRI and FDG-PET showed no area of lymphomatous involvement other than the vagina and direct involvement into the bladder. She achieved complete response (CR) after chemotherapy followed by localized radiation therapy, but she had a relapse in the central nervous system (CNS) two months after CR. A study of 57 reported cases of primary vaginal lymphoma suggested that the most common histologic type was DLBCL, and most of patients were in a localized stage and responded well to combination of chemotherapy and radiation therapy. To date, two cases of primary vaginal lymphoma with a relapse in the CNS have been reported. We presumed that direct involvement into the bladder of vaginal lymphoma contributed to the relapse in the CNS in this case.
