Primary bone marrow lymphomata are infrequent; most of them are of B-cell origin, and those of a T-cell lineage produce mainly both hypercalcemia and osteolytic lesions apparently due to abnormal production of osteoclast-activating factor. We report a 15-year old patient with a primary bone marrow lymphoma: 85% of his infiltrating malignant lymphocytes displayed cytoplasmic mu-chains compatible with a pre-B phenotype. The cells failed to display the CALLA/CD 10 antigen. Serum calcium was 7.5 mEq/L (range 4-5 mEq/L); the bone biopsy of an osteolytic lesion disclosed a large-cell, diffuse non-Hodgkin's lymphoma. No malignant cells were found in the peripheral blood and there were no enlarged lymph nodes. The patient was treated with 6 courses of chemotherapy: hydroxyldaunorubicin, vincristine and prednisone (HOP). Complete remission was achieved and the patient was placed on continuation chemotherapy with daily six-mercaptopurine and weekly methotrexate, together with HOP pulses every three months. The hypercalcemia disappeared together with the fever and the bone pain: the patient has been followed 6 months. Data on this case are discussed together with those previously published in regard to the low prevalence of bone lesions in primary B-cell lymphomas of the bone marrow, and to the similarity of this B-cell malignancy to others that produce both hypercalcemia and bone lesions, i.e. multiple myeloma.

Non-Hodgkin's lymphomas uncommonly present as bone lesions. Most of these tumors are diffuse large B-cell lymphomas. Anaplastic large cell lymphoma (ALCL) presented as bone lesions is exceedingly rare. In this study, we describe six cases of ALCL that presented as solitary or multiple bone lesions. The average patient age was 33 years (range, 4 to 63 years) and the male to female ratio was 2:1. Fever and localized bone pain were the most frequent presenting symptoms. Radiologic examinations revealed osteolytic lesions in all cases, with three (50%) being multiple lesions and five (83%) involving the axial bones. All patients were initially assessed to have only bone involvement. Staging studies revealed mild cervical lymphadenopathy in one patient and no evidence of extraskeletal disease in the other five patients. Histologically, there was diffuse infiltration of one or more bones by large pleomorphic lymphoma cells. Immunohistochemical studies showed all six neoplasms were positive for CD30, EMA, and granzyme B. One case was of T-cell lineage, positive for CD3. One case was positive for the T-cell-associated antigen CD4. The remaining four cases were of null-cell type. In-situ hybridization for EBV was performed in five cases; all were negative. Despite the relatively low International Prognostic Index (IPI) of these patients (mean, 1.67; range, 1 to 3), the overall prognosis was relatively poor: three of six died of disease within 2 years of diagnosis, and two of six were alive with evidence of disease (follow-up, 6 mo to 2 years). Thus, compared to their nodal counterparts, ALCLs that present as bone lesions are distinguished by their uniform expression of EMA and granzyme B, and a relatively poor clinical outcome. Our results also suggest that ALK-1 expression in this clinical setting is not a favorable prognostic indicator.

Primary non-Hodgkin's lymphoma of bone (PLB) is a rare disorder representing less than 1% of all non-Hodgkin's lymphomas and has rarely been reported in Taiwan. A retrospective clinicopathological study was performed according to the 2002 World Health Organization criteria and identified 14 cases during a 13-year period in 2 medical centers in southern Taiwan. There was male predominance (M:F = 6:1) with a median age of 42 and bone pain (6 patients, 43%) as the most common symptom. Half of the patients had monostotic and the other half polyostotic lesions. Axial skeletons (10 cases, 71%) were the most frequent sites of involvement. The staging results were stage I (9 patients, 64%), stage II (2, 14%) and stage IV (3, 21%). Eight cases (57%) were of B-cell phenotype and the remaining 6 (43%), T-cell. Histologically, 7 (50%) were diffuse large B-cell lymphomas (DLBCLs) and 5 (36%) anaplastic large cell lymphomas. Seven patients received chemotherapy and radiotherapy; 4 chemotherapy and 3 radiotherapy alone. Of the 11 patients with follow-up information, 6 (55%) died of disease within 1 year including 5 with T-cell lymphomas, while all the 5 patients surviving over 1 year were of B-cell phenotype. The overall 1-year survival rate was 45%. The survival of B-cell lymphomas was significantly better than T-cell tumors (p = 0.016, log-rank test). In summary, this study reported the largest series of PBL in Taiwan and confirmed that the majority was DLBCL and B-cell tumors had more favorable prognosis. As compared to the Western series, the cases showed a striking male predominance, higher percentage of axial skeleton involvement, higher relative frequency of T-lineage tumors and poorer prognosis.

Primary lymphomas of bone are uncommon malignancies. The vast majority of them are non-Hodgkin lymphoma (NHL), whereas primary Hodgkin lymphoma (HL) of bone is extremely rare. Patients with primary NHL of bone commonly present with local bone pain, soft tissue swelling, and a mass or a pathological fracture. There is a slight male preponderance, and most patients are over 45-50 years of age. Primary NHL of bone can arise in any part of the skeleton, but long bones (femurs, tibia) are the most common sites of presentation. Comprehensive immunohistochemical studies are required to establish an accurate histological diagnosis of primary NHL of bone. Most cases of primary NHL of bone are classified as diffuse large B-cell lymphomas (DLBCL) in the World Health Organisation (WHO) classification of hematological malignancies. On full staging evaluation, most patients have disease of stage IE or IIE according to the Ann Arbor system. Several studies indicate that patients with primary NHL of bone have a favorable outcome, especially when treated by combined modality therapy. A number of studies reported that clinical stage is the most important prognostic variable in predicting overall survival. Interestingly, the rare occurrence of primary lymphoma of bone is in contrast with the frequency of plasma cell tumors in bone. This could be due to the fact that, during normal B-cell differentiation, the bone marrow is the normal site of homing of plasma cells which are terminally-differentiated, immunoglobulin-secreting post-germinal center B-cells. In this respect, there is circumstancial evidence that primary NHL of bone may represent tumors of post-germinal center B-cells. The present review summarizes data on the histogenesis of primary NHL of bone in view of the recent histogenetic classification of DLBCL on the basis of the B-cell differentiation gene expression profiles (germinal center vs. post-germinal center B-cell differentiation).

Primary bone lymphomas are rare, even though secondary involvement of the bone marrow is a common event in systemic lymphomas. Most primary bone lymphomas are primary bone diffuse large B-cell lymphomas (PBDLBCLs) with a rare occurrence of follicular, marginal zone, anaplastic large cell, Hodgkin, and T-cell lymphomas. The PBDLBCL affects the middle-aged to elderly population, with a slight predominance in men. The patients present with bone pain, palpable mass, fractures, or neurologic symptoms. The metaphysis of bones is a common location of PBDLBCL. Morphologically, the lymphoma consists of a polymorphous mixture of small to large cells with multilobated nuclei, fine chromatin, and inconspicuous to prominent nucleoli. Differential diagnoses for PBDLBCL include chronic osteomyelitis, primary bone sarcoma, leukemic infiltrate, Ewing sarcoma, metastatic sarcomas, and carcinoma. Most PBDLBCLs are treated with combined radiotherapy and chemotherapy with good prognosis.

The purpose of this study was to investigate the clinical signs and therapy of primary lymphoma of bone (PLB). One primary lymphoma of bone is described, and review of the pertinent literature is introduced. The patient achieved complete remission with no evidence of local recurrence. PLB are uncommon malignancies. Patients with PLB commonly present with local bone pain, soft tissue swelling and a mass or a pathological fracture. Most cases of PLB are classified as diffuse large B-cell lymphomas in the WHO classification of hematological malignancies. Comprehensive immunohistochemical studies are required to establish an accurate histological diagnosis of PLB. Early diagnosis and active treatment can improve the prognosis.

Non-hodgkin`s lymphoma (NHL) is the most common haematological malignancy which is seen in HIV infected patients. Among NHLs, immunoblastic lymphomas are most common and a majority of these are diffuse large B-cell lymphomas. Multiple myeloma is a disease of the elderly. It is extremely rare below 30 years of age. On the other hand, in HIV infected individuals, the average age of presentation with plasma cell disorders is 33 years, which is far younger than the average age of presentation in general population. The incidence of AIDS defining malignancies has declined markedly, whereas non-AIDS defining cancers are being increasingly diagnosed in patients with HIV infection during the HAART-era and they may be the presenting manifestations of AIDS. Multiple myeloma, however, usually is not a first presenting feature of AIDS. The usual clinical presentation of multiple myeloma is bone pain and pallor. Pancytopaenia is a rare presenting feature of multiple myeloma. Here, we are reporting a case of pancytopaenia which occurred in a 28-year-old, newly diagnosed, HIV-1 positive female, who with the help of bone marrow examination and further investigations, was subsequently diagnosed as multiple myeloma.
