Genetic alterations in the p107 gene, a close relative of the retinoblastoma tumor suppressor gene, have never been identified in human malignancies. When we searched for such alterations in human hematologic malignancies by Southern blot analysis, 2 of 21 cell lines and 1 of 88 primary disorders had genomic alterations within the gene. Particularly, an altered p107 gene in a diffuse-large B-cell lymphoma cell line, KAL-1, harbored an intragenic deletion of about 15 kbp leading to the expression of an altered p107 mRNA devoid of 819 nucleotides of the coding sequences, which predicts to encode an approximately 87-kDa protein. This cell line was found to express solely a p107 derivative of 84 kDa by immunoblotting analysis. These results suggest that alterations in the p107 gene are probably related to a limited subset of human hematologic malignancies.

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.
