The vast majority of the human experience with viral infections is associated with acute symptoms, such as malaise, fever, chills, rhinitis and diarrhea. With this acute or lytic phase, the immune system mounts a response and eliminates the viral agent while acquiring antibodies to that specific viral subtype. With latent or chronic infections, the viral agent becomes incorporated into the human genome. Viral agents capable of integration into the host's genetic material are particularly dangerous and may commandeer the host's ability to regulate normal cell growth and proliferation. The oncogenic viruses may immortalize the host cell, and facilitate malignant transformation. Cell growth and proliferation may be enhanced by viral interference with tumor suppressor gene function (p53 and pRb). Viruses may act as vectors for mutated proto-oncogenes (oncogenes). Overexpression of these oncogenes in viral-infected cells interferes with normal cell function and allows unregulated cell growth and proliferation, which may lead to malignant transformation and tumour formation. Development of oral neoplasms, both benign and malignant, has been linked to several viruses. Epstein-Barr virus is associated with oral hairy leukoplakia, lymphoproliferative disease, lymphoepithelial carcinoma, B-cell lymphomas, and nasopharyngeal carcinoma. Human herpesvirus-8 has been implicated in all forms of Kaposi's sarcoma, primary effusion lymphomas, multiple myeloma, angioimmunoblastic lymphadenopathy, and Castleman's disease. Human herpesvirus-6 has been detected in lymphoproliferative disease, lymphomas, Hodgkin's disease, and oral squamous cell carcinoma. The role of human papillomavirus in benign (squamous papilloma, focal epithelial hyperplasia, condyloma acuminatum, verruca vulgaris), premalignant (oral epithelial dysplasia), and malignant (squamous cell carcinoma) neoplasms within the oral cavity is well recognized. Herpes simplex virus may participate as a cofactor in oral squamous cell carcinoma development by enhancing activation, amplification, and overexpression of pre-existing oncogenes within neoplastic tissues. Because of the integral role of viruses in malignant transformation of host cells, innovative antiviral therapy may prevent tumour development, involute neoplastic proliferations, or arrest malignant progression.

POEMS syndrome is a rare condition with cutaneous manifestations commonly including angiomas, hypertrichosis, hyperpigmentation, and thickening of the skin. We describe a male patient with a 2-year history of cervical lymphadenopathy, erythematous thickening of the skin on the neck, and progressive walking difficulties. The patient had an occipital erythema with scarring alopecia and sparse follicular pustules at the edge of the lesion. Further investigation revealed symmetric polyneuropathy, hepatosplenomegaly, monoclonal gammopathy, subclinical thyreopathy, and an osteolytic bone lesion of the skull. Histologically, a plasmacytoma with lambda cell restriction was found. The overlying skin showed marked fibrosis, with loss of hair follicles, and a plasma cell infiltrate of polyclonal origin. The cervical lymph nodes showed histologic characteristics of multicentric Castleman's disease, and the skin of the neck showed thickening and vasoproliferation. There was no evidence of further plamacytomas. After excision of the plasmacytoma and postoperative irradiation, the symptoms gradually resolved within a few months. A cicatricial lesion remained on the occiput without further folliculitis or hair loss on the rest of the scalp. This case illustrates the reactive character of POEMS syndrome as a paraneoplastic syndrome in myeloma patients.

We report a case of erythema elevatum diutinum (EED) in association with malignant B-cell lymphoma. A 62-year-old man developed EED with an unusual distribution involving the palms, soles and nails. Treatment with dapsone was effective for his skin and nails until he developed generalized lymphadenopathy which turned out to be malignant lymphoma. Many haematological diseases, e.g. IgA paraproteinaemia and myeloma, have been reported in association with EED, but not malignant lymphoma. Even though it may just be a coincidence, we would like to add malignant lymphoma as one of the diseases associated with EED because the activity of EED and malignant lymphoma fluctuated in parallel.

Waldenstrom's macroglobulinemia (WM) is an uncommon B cell malignancy that resembles other B cell malignancies, such as multiple myeloma and chronic lymphocytic leukemia. WM's clinical course varies widely, with survival ranging from 1-16 years. WM is diagnosed when a bone marrow biopsy reveals malignant B-lymphocytes arrested at the plasmacytoid lymphocytic stage of the maturation process and when high levels of IgM are found in the serum blood. Common clinical features include anemia, abnormal bleeding, and hyperviscosity, and 20%-40% of patients present with lymphadenopathy or splenomegaly. Alkylating agents have been the most common chemotherapy agents used to treat WM. However, nucleoside analogues are being used more frequently with promising results. Nursing care includes educating the patient about the disease trajectory, providing symptom management, and monitoring the patient's response to treatment.

Adult T-cell leukemia (ATL) is endemic in southwestern Japan, in the Caribbean islands, and in central Africa. Human T-cell lymphotropic virus type I (HTLV-I) is the etiologic agent of ATL. The clinical characteristics are (1) onset in adulthood, (2) subacute or chronic leukemia with rapidly progressive terminal course, (3) frequent skin lesions, (4) lymphadenopathy that characteristically spares the mediastinum, (5) hepatosplenomegaly, (6) hypercalcemia, and (7) a tendency toward geographical clustering. Although hypercalcemia and osteoclastic activity due to parathyroid hormone-related peptide are frequently reported histologically, radiographic abnormalities of bone are not common. Two major patterns of osteolytic lesions observed in ATL are "punched-out" lesions resembling multiple myeloma and osteolytic metastasis and subperiosteal bone resorptions similar to those in hyperparathyroidism.

Multicentric Castleman's disease (MCD) is a lymphoproliferative disorder characterized by systemic lymphadenopathy and hypergammaglobulinemia. Recently, a French group reported that human herpesvirus 8 (HHV8) DNA was detected in tissue samples of MCD patients. The detection rate was especially high in human immunodeficiency virus (HIV)-positive MCD patients. Thus, HHV8 infection seems to be closely related to HIV infection. In Japan, the HIV infection rate in the general population is very low. To examine whether HHV8 is actually related to MCD in Japan, we performed nested polymerase chain reaction for the HHV8 genome using DNA samples from 7 patients with MCD and 23 patients with related diseases such as POEMS syndrome, amyloidosis, myeloma and lymphoma. They were all HIV-negative Japanese. Three of 7 MCD patients were positive for HHV8. There were no clear differences in clinical characteristics between HHV8-positive patients and negative ones. All other patients were negative for HHV8. Thus, we have shown that some MCD patients in Japan are also infected with HHV8.

A 75-year-old woman was referred to us because of cough, high fever and skin erythema in April 1999. Malignant lymphoma (diffuse mixed cell type) was previously diagnosed in 1990 and she achieved complete remission after treatment with a series of CHOP regimen treatments. In 1998, multiple myeloma (IgG lambda type) was diagnosed and she was treated with a combination of melphalan and prednisolone. On physical examination, superficial lymphadenopathy and skin erythema were noted. Biclonal gammopathy (IgG kappa/lambda) was shown in serum, and Bence Jones protein in urine. Computed tomography showed pleural effusion and swelling of paraaortic lymph nodes. The bone marrow examination showed an increased number of abnormal plasma cells (19.2%) and no evidence of lymphoma. Left axillary lymph node biopsy revealed that she had non-Hodgkin's lymphoma (immunoblastic lymphadenopathy-like T cell lymphoma). She was treated with the CHOP regimen at reduced doses for both diseases. The lymphoadenopathy reduced after 6 courses of CHOP and 4 courses of CHOPE (CHOP + VP16), however, she had bone pain on November 1999 and received treatment with MCNU-VMP (MCNU + VDS + L-PAM + PSL). Her rib pain improved, but she died of systemic infection of herpes zoster virus. We report here a rare case of malignant lymphoma concomitant with multiple myeloma.

We describe the establishment and characterization of a new multiple myeloma (MM) cell line, KYdelta-1, which expressed delta/kappa type immunoglobulin (Ig). The patient was a 65-year-old woman with MM, who presented extramedullary dissemination, lymphadenopathy and short survival. The KYdelta-1 cell line was derived from the pleural fluid obtained in the terminal phase of the disease. The cells expressed delta/kappa Ig in the cytoplasm, and CD10, CD29, CD33, CD38, CD44, CD54, and HLA-DR antigens on the cell surface. Chromosomal analysis revealed two independent translocations, t(3;14)(p21;q32) and t(3;11)(p21;q13), which were confirmed by fluorescence in situ hybridization using chromosome painting probes. Reverse transcriptase-mediated polymerase chain reaction (PCR) and Northern blot analyses demonstrated overexpression of the CCND1 gene, suggesting alteration of the BCL1-CCND1 locus. We thus performed long-distance inverse PCR using nested primers for the Calpha constant region of immunoglobulin heavy chain gene (IGH) and obtained a clone that encompassed the 11q13/IGH fusion. Nucleotide sequencing determined that the fusion occurred at the Salpha2 switch region and at the centromeric side of the major translocation cluster of BCL1. The other IGH allele consisted of a VDJ complex that was adjacent to the Cdelta constant gene, indicating that a class switch-like mechanism from the C(mu) to Cdelta was involved in the production of the Ig delta heavy chain. Point mutations within the P53 and N-RAS genes were presumably related to the rapidly progressive disease in this particular MM patient.

In a 52-year-old man with general malaise, muscle stiffness and weakness, POEMS-syndrome was diagnosed based on polyneuropathy, splenomegaly, lymphadenopathy, subclinical hypothyroidism and the presence of a monoclonal paraprotein with osteosclerotic lesions and an indurated skin (POEMS is an acronym for Polyneuropathy, Organomegaly, Endocrinopathy, Monoclonal protein, Skin changes). This is a rare systemic disease from the clinical spectrum of plasma cell dyscrasias with polyneuropathy. The clinical picture is broader and more pleomorphic than the acronym suggests. The possibility of a POEMS syndrome should be considered in the differential diagnosis of polyneuropathy in association with monoclonal gammopathy. Quite often it is associated with osteosclerotic myeloma or mixed osteoscleroticlytic lesions. The patient described was treated with high dose corticosteroids which were gradually decreased over the next three months, upon which a marked improvement could be seen. The general malaise subsided, as did the splenomegaly, and the skin became supple again.

We report three cases of post-transplant lymphoproliferative disorder (PTLD) in the context of autologous stem cell transplantation (ASCT) for multiple myeloma (MM) and non-Hodgkin's lymphoma. The first two cases received ASCT for MM, one with a CD34-selected autograft and the other with an unmanipulated autograft. Both these cases of PTLD achieved a complete response following treatment with IVIG, gancyclovir, solumedrol and interferon (IFN). The third case received ASCT with an unmanipulated autograft for relapsed angioimmunoblastic lymphoma. He also achieved a complete response but only after rituximab was added to IVIG, gancyclovir, solumedrol and IFN. None of these patients experienced a relapse of their PTLD with follow-up ranging from 1.5 to 5 years. These cases highlight the importance of considering PTLD in the differential diagnosis of lymphadenopathy and fever post ASCT. They also demonstrate the possibility of durable complete remission of post-ASCT PTLD following antiviral and immune modulating therapy.
