NK/T-cell lymphomas which are characterized by the biphenotype of the NK-cell and the T-cell are divided into nasal and non-nasal NK/T-cell lymphoma, non-nasal NK/T-cell lymphoma is then further subdivided into primary cutaneous and 4 subtypes of secondary cutaneous lymphoma such as nasal type, aggressive, blastic(blastoid), and other specific NK-like T-cell lymphoma. Primary cutaneous NK/T-cell lymphoma is a very rare condition and defined as a lack of extracutaneous disease for at least 6 months from the time of diagnosis. We herein report a case of non-nasal NK/T-cell lymphoma, which is consistent with primary cutaneous type.

Determine immuno-phenotip of non-Hodgkin's malignant lymphomas, it might perform on paraffin embedded specimen on research 28 cases according to histological method suggested that cell B lymphomas is highest rate (54,17%), second cell T lymphomas (25%), other kinds had low rate. Cell B lymphomas is higher two fold than cell T lymphomas. Some cases of high level maligent lymphomas were tested immunohistochemistry to determine EBV antigen or EBV genom, but results still is negative

PURPOSE: The authors evaluated the usefulness of the positron emission tomography (PET) with fluorine-18-tluorodeoxyglucose (8F-FDG) in initial staging, reevaluation after radical therapy and diagnosis of recurrence for non-Hodgkin's lymphoma, compaired to conventional imaging studies. MATERIALS AND METHODS: FDG-PET (ECAT Exact 47, Siemens) and conventional chest X-ray and computerized tomography (CT) were studied in patients with non-Hodgkins lymphoma. RESULTS: There were 17 patients (13 male, 4 female). Age was ranged from 18 to 62 years (median 49). By histological subgroup, diffuse large cell were 8 cases, peripheral T cell were 2 cases, diffuse mixed was 1 case, follicular mixed was 1 case, Burkitt's lymphoma was 1 case, Hodgkin's disease were 3 cases. The aims for PET were the initial staging work-up in 7 cases, the reevaluation of residual disease after radical therapy in 7 cases, the diagnosis of recurrence after complete remission in 3 cases. Between PET image and the conventional image, there were 3 cases with discrepancy, 1 case for initial staging work-up and 2 cases for the reevaluation of residual disease after radical therapy. Among the 3 cases with discrepancy, the 2 cases for the reevaluation of residual disease after radical therapy revealed that PET image reflects the involvement of lymphoma more accurately than the conventional image. CONCLUSION: The visual analysis of FDG-PET would be helpful in determining the residual disease of lymphoma after radical therapy.

Lymphoproliferative disorders of the lung consist of a spectrum of several entities from malignant lymphoma to variable non-lymphomatous lymphoproliferative disorders. While an entity may be histologically benign and can be cured without treatment or by surgical removal, malignancy may evolve, and aggressive treatment may thus be required. Radiographic and pathologic findings of an entity may overlap, but differential diagnosis of lymphoproliferative disorders of the lung is nonetheless important. In this paper we illustrate a variety of lymphoproliferative diseases of the lung that have been pathologically proven during the last ten years, and discuss their radiographic and pathologic characteristics.

Extranodal NK/T-cell lymphoma (NTCL), nasal type is rare and highly fatal malignant neoplasm. Early diagnosis and establishing treatment plan are very difficult. Furthermore, NTCL in the mandible is an extremely rare condition. The clinical significance of presented case is the very rare location of NTCL. To the best of author's knowledge, this is the first reported case of NTCL of the mandible in the literature.

Heterotopic panereas is pancreactie tissue occuring outside its normal anatomical location and without any connection and normal pancreas and it is a developmental anormaly. The most commen site is stomach(esp. greater curvature of the antrum), duodenum and jejunum, In majority of cases heterotopic pancreas does not produce symptoms. When it produces complications, the symptoms depend on the site of lesion and the size of mass. Pathologically, the heterotopic pancreatic tissue is subject to all the lesions found in the normally placed pancreas. Tbe smooth broad base intramural defect with central niche ie typical radiologic fiadings of heterotoPic pancreas. Gastrofiberscopy revealed a small round, submucosal projection with a central umblication. The lesions are frequently confused with polys, lymphoma, in.tramural neoplasm and gastric uleer. Accurate diagnosis may prevent needless surgical procedures. Three cases of heterotopic pancreas of stomach were reported and the pertinent literature were reviewed briefly.
