Background: The role of Epstein-Barr virus (EBV) in the appearance of some sort of B-cell neoplasm such as Burkitt's LYMPHOMA has approximately been proved. With respect to the prevalence of Burkitt's LYMPHOMA in Iran and related topics on treatment and prevention, the present study has assessed the association between the EBV and Burkitt's LYMPHOMA.Materials and methods: It was a descriptive study. Paraffin-embedded blocks of 101 samples with the diagnosis of Burkitt's LYMPHOMA were studied using immunohistochemistry and histochemistry techniques in Kiel University in Germany.Results: Of 101 samples, the diagnosis of Burkitt's LYMPHOMA was confirmed in 65 cases (64.5%), among which 3 cases (4.6%) had been infected by EBV.Conclusion: Since there was a weak association between EBV and Burkitt's LYMPHOMA and also with respect to the prevalence of Burkitt in Iran, other possible etiologic factors should be considered.

Primary cutaneous CD30+ T cell LYMPHOMA is a rare LYMPHOMA originally in and confined to the skin. These LYMPHOMAs usually present as a large solitary and often ulcerated nodule. Its prognosis is good and has a good response to radiotherapy. We report a 34-year-old man, who had primary cutaneous CD30+ T cell LYMPHOMA on his face, which presented as an ulcerated nodule.    

In Islamic traditional textbooks modal operators sometimes come before propositions, sometimes before the predicates and sometimes at the end of propositions. This makes the interpretation of modality in each case as de re or de dicto difficult. Given Ibn SVnÏ's discussion of and sensitivity to this distinction, in this paper by examining the position of modality in the contradictories and converses of modal categorical propositions as well as their positions in modal syllogisms I will try to find a reasonable answer to this important issue.

Diffuse normolipemic plane xanthoma is a rare disorder often seen as a para- neoplastic manifestation accompanied with gammopathics and hematologic disorders. In this report, a 44-year-old man IS presented who was referred to us due to developing erythematous papules on the hands and yellow patches on different parts of the body. Based on cell blood count, peripheral blood smear and positive anti HTL VI, the diagnosis of adult T cell LYMPHOMA/leukemia was suggested which confirmed by the biopsy of the hand lesions. The histopathologic evaluation of yellow lesions also confirmed the diagnosis of diffuse xanthoma.

Anaplastic large-cell LYMPHOMA is an aggressive non-Hodgkin LYMPHOMA of T cell/null cell origin. It rarely affects the gastrointestinal tract. We present the case of a 58-year-old patient diagnosed with anaplastic LYMPHOMA of the stomach in association with Kaposi’ s sarcoma of the skin.

Background and Objective- High-dose chemotherapy with stem cell rescue has emerged as the treatment of choice for patients with refractory and relapsed non-Hodgkin’s LYMPHOMA (NHL). To evaluate the efficacy and toxicity of a novel chemotherapy regimen with mesna, Ifosfamide novantrone and etoposide (MINE) in patients with relapsed NHL previously treated with adriamycin-based regimens. Methods-Forty-six patients with relapsed NHL were treated in this study. The median age was 42 years (range 13-65). Twenty-eight patients (60.8%) had high grade, 10 (21.7%) had low grade and the rest had intermediate grade LYMPHOMA. The program utilized cyclic administration of ifosfamide 1.33 gm/m2 day 1-3, mesna 1.33 gm/m2 day 1-3, etoposide 100 mg/msup>2 day 1-3, novantrone 12 mg/m2 day 1. Cycles were repeated every 3 weeks for 6 cycles. Mean while, adequate hydration was also provided. Results-The overall response rate was 65.2% (30 patients). Complete response was achieved in 30.4% (14 patients) and a partial response in 34.8%. The median survival period was 7 months. Grade III neutropenia was seen in 10 patients (21.7%) and grade IV in 1 patient who died of treatment-related toxicity. Conclusion-MINE combination is an effective and well tolerated treatment for patients with relapsed NHL who have no chance for bone marrow transplantation.
