© 2004, Institute of Oncology Sremska Kamenica,Serbia and Montenegro 71 Case report UDC: 616-006.44:616.831-002 INTRODUCTION araneoplastic neurological syndromes (PNSs) present as remote neurological effects of cancer in which nervous system dysfunction develops without evidence of direct invasion of tumor into neural tissue or of infectious or vascular complica- tions. PNSs occur in about 1% to 6% of all cancer patients. Almost all tumor types may be associates with PNSs, but small cell lung cancer (SCLC), thymoma, ovary and breast cancer are by far the most common. Testicular carcinoma, melanoma, and lymphoma are less likely to trigger the PNSs. Paraneoplastic limbic encephalitis (PLE) is a rare disorder char- acterized by psychiatric symptoms, seizures, and short-term memory loss. Symptoms may precede the tumor diagnosis by some months. At least half of the patients harbor ...

Abstract An unusual case of stage D Burkitt’s lymphoma in a 24 year old Nigerian female undergraduate is reported. There was a four month history of left lower lip paraesthesia followed three months later by a slowly progressive ‘pimple-sized’ nodular mandibular swelling arising from the mental foramen region. A full-blown, rapidly developing abdominal mass manifested only three weeks after a biopsy of the mandibular swelling. Aspiration of the latter and a histologic report of the mandibular mass confirmed Burkitt’s lymphoma . The patient responded very well to appropriate chemotherapy. Clinicians should not overlook insidious jaw swellings in any adult residing in the endemic zone of Burkitt’s lymphoma , in view of the fact that successful therapy is dependent on early diagnosis. Mental nerve paraesthesia is very rarely seen in Burkitt’s lymphoma . Key words: ...

      PDF [93,7 KB]  From [www.aans.org]  Last viewed: 30.07.2004
Neoplasms of the sacrum are relatively uncommon, representing 1 to 2% of all musculoskeletal tumors. 2 They can be classified as primary or metastatic lesions, the for- mer being either benign or malignant. The most common malignancy of the sacrum is metastatic disease, whereas the most common primary sacral tumor is chordoma. Other sacral malignant lesions include Ewing sarcoma, myeloma, osteosarcoma, neurofibrosarcoma, angiosarco- ma, chondrosarcoma, and rarely lymphoma . Referred pain in the leg or buttock is the typical presenting symptom of sacral tumors. Neurological signs are rarely seen, and their manifestation is often late. We describe two rare cases in which diffuse large B-cell lymphomas presented as pri- mary malignant sacral tumors. CASE REPORTS Case 1 History. This 52-year-old man presented with a 3-week history of increasing back pain radiating down ...

elderly patients with AML less is more . Many patients, surprisingly including the group with the most favor- able prognosis, did not profit from standard induction therapy and had a comparable outcome with palliative therapy. However, in some patients, such as those with a high white cell count, standard induction therapy may be superior to palliative therapy. Clearly, further studies to evaluate risk factors, molecular biology and detailed quality of life aspects of the elderly patients with AML are needed. If we learn more about the diversity of AML in the elderly, we will be able to cre- ate differential treatment strategies with better risk- benefit ratios for the individual patient and responsi- ble use of existing resources. This could result in a gen- eral improvement of the unfavorable outcome of eld- erly AML patients, which has remained almost un- changed sinche the 1980s. ...

  [1631] Molecular insight into the diagnosis of lymphoma
      PDF [89,7 KB]  From [147.52.72.117]  Last viewed: 30.07.2004
Abstract. Malignant lymphoma may be very difficult to diagnose with routine histopathological methods because they may recapitulate benign architecture or contain benign infiltrates. The best method of diagnosis is to establish the clonal profile of the lymphocyte population, since a mono- clonal proliferation is highly suggestive of neoplasia. By means of a PCR (polymerase chain reaction) method it is possible to detect the immunoglobulin heavy chain (IgH) gene rearrangement and therefore establish the lymphocyte clonality. PCR with primers complementary to relatively conserved regions called frameworks (FR1-FR3) laying among hyper variable regions (CDR1-CDR3) of IgH gene unable us to detect monoclonal versus polyclonal B-cell population. The length of the PCR product with these primers is unique if we deal with a monoclonal population. On the contrary, a polyclonal population gives PCR products ...

Abstract. Undifferentiated carcinoma of the nasopharyngeal type (UCNT) that histologically mimics Hodgkin's lymphoma (HL) (‘Hodgkin's lymphoma -like UCNT’ - HL-like UCNT) is known as a diagnostic pitfall. Using immunohistochemistry, Western blot and cDNA array technology, we wanted to document its phenotypical and molecular characteristics. We report herein 5 cases of UCNT that morphologically mimic HL and 3 classical UCNT cases. We compared the expression profiles of a thousand selected genes in HL-like UCNT and in classical UCNT cases. No difference in the profile of EBV infection was noted between the HL-like UCNT and control cases. Significant differences were detected in the expression of genes involved in the matrix modelling, angiogenesis, apoptosis and regulation of the Th-2 interleukins. The eosinophil chemoattractant eotaxin was expressed in the stroma of HL-like UCNT, but not ...

Journal of the National Cancer Institute 78(2): 247–252 (Feb., 1987). Grain workers’ mortality rates from particular causes of death were studied using union insur- ance records. Information concerning pesticide use was also gathered. The authors found that pesticides used in the grain industry include aluminum phosphide (phosphine), carbon disul - fide, carbon tetrachloride, ethylene dibromide, ethylene dichloride, Malathion, and methyl bro- mide. In this study of the deaths of 1,114 white males, findings indicated increased risk of lym- phoma among grain mill workers (prompting a later study — see below).

© 2003, Institute of Oncology Sremska Kamenica,Serbia and Montenegro 21 Case report UDC: 616-006.44:616.8-009.86 INTRODUCTION ntravascular lymphoma (IVL) is a very rare form of non- Hodgkin's lymphoma , characterized by widespread intravascular proliferation of malignant lymphoid cells often pre- senting with nonspecific clinical features and extremely poor prognosis. The terminology used to describe this entity is variable and suggests endothelial origin of neoplastic cells. The most used term is neoplastic (malignant) angioendotheliomatosis or angioendotheliosis. However, there is conclusive evidence that this tumor represents a special form of malignant lymphoma (1- 4) and therefore intravascular lymphoma is the most appropriate name for this disease. Although not specifically recognized by the Revised European-American Classification of Lymphoid neo- plasms, ...

Abstract. Whether a common and a single clone present, or not, among follicles of follicular lymphoma (FL) was examined in 12 cases with FL. Histologic grade was I in 6 cases, II in 3, and III in 3. DNA was selectively extracted from the neoplastic follicles of paraffin-embedded samples with use of laser capture microdissection method, and used for PCR-based analysis of rearrangement of immunoglobulin heavy chain variable region gene. Three different follicles in each case of FL were microdissected. Semi-nested PCR was performed using two sets of primers (Fr2A and Fr3A). In PCR with Fr2A primers, nine of 12 cases showed a common band among neoplastic follicles. The remaining three cases showed no PCR products. With Fr3A primers, eight of 12 cases showed a common band among follicles of the same case. The other four cases showed oligoclonal bands, among them presence of a common band was difficult ...

Abstract. The aim of the study was to investigate the incidence of thyroid abnormalities in neck irradiated lymphoma patients. Of the 298 patients who had irradiation to the neck for lymphoma between 1966-1988, 174 were found to be alive and free of disease. These patients were invited to participate in the study. From the 174, 93 were able to participate (group 1). Two control groups were recruited; both were sex and aged matched. One group (group 2) consisted of lymphoma patients who were treated with chemotherapy (n=39) or irradiation to areas other than the neck (n=16). The other group (group 3) consisting of healthy volunteers (n=35) recruited from hospital staff and minor surgery attendees, had never had lymphoma or radiotherapy. All participants were required to complete a past medical history and thyroid symptom questionnaire, had blood taken for assays of thyroid stimulating ...

Abstract. High-grade B-cell non-Hodgkin's lymphoma (NHL), a diagnostic disease for the acquired immunodeficiency syndrome (AIDS), is a late manifestation of HIV infection and is generally related to severe lymphopenia. We reviewed the main clinico-pathological features of this disease and analysed its pathogenetic mechanisms with potential therapeutic implications. Contents 1. Introduction 2. Pathogenetic mechanisms 3. Molecular and histopathological characteristics 4. Clinical aspects 5. Diagnosis and staging evaluation 6. Prognosis 7. Therapy 8. Conclusion 1. Introduction High-grade B-cell NHL is, together with Kaposi's sarcoma (KS) and invasive cervix cancer, an AIDS-defining disease (1). It occurs late in the natural history of HIV infection and is generally associated with severe lymphocytopenia. Though representing the cause of death in 12-16% of HIV ...

Abstract. Reduced apoptosis is associated to cancer development. Agents able to restore the programmed cell death responsiveness of cancer cells are foreseen as potential effective cancer therapies. In this study, we report that a glutathione-S-derivative, S-acetyl-glutathione (Sag), induces significant apoptosis in three human lymphoma cell lines, including Daudi, Raji and Jurkat cells while it had no or little effect on either Hut-78 lymphoma cells or the normal BT lymphocytes. We used Annexin-V FACS analysis and DNA laddering to demonstrate that Sag activated apoptosis in the three sensitive cell lines in a dose- and time-dependent- fashion. Using mercury orange staining and FACS analysis, we showed that Sag generated an intracellular GSH depletion in Daudi, Raji and Jurkat cells but not in Hut-78 or the normal BT cells. These data provide direct evidence that Sag specifically activates ...

eprosy is an ancient disease, and although the treatment for leprosy has been available for several decades, the number of cases of lep- rosy worldwide was recently estimated to be approximately 5.5 million. 1 Most cases of leprosy occur in tropical countries. In the United States, indigenous transmission has been recorded in Hawaii, Pacific island territories, and sporadically along the Gulf Coast. 2 Generally, patients with leprosy do not experience increased morbidity as a result of viral, fungal, or pro- tozoal infections, for which cellular immunity is an important defense mechanism. Mycobacterium leprae infection has not been shown to predispose patients to an increased risk for neoplasia, 2 and Hodgkin’s lymphoma has rarely been reported in a patient with leprosy. 3 In contrast, several cases of leprosy have been ...

Acta Nephrologica Primary renal lymphoma 147 INTRODUCTION Systemic non-Hodgkin lymphoma with renal in- volvement is not an uncommon clinical presentation 1 . In contrast, primary renal lymphoma is an extremely rare tumor. To our knowledge, only about 39 cases have been reported since 1926 2-5 .
