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.

To study the differentiating cytomorphological features of Hodgkin lymphoma (HL) and anaplastic large cell lymphoma (ALCL) using fine needle aspiration cytology (FNAC), cytomorphological features of 16 patients with HL (n=8) or ALCL (n=8) were analyzed. In the initial cytological diagnosis prior to biopsy, HLs were properly diagnosed in 4 out of 8 cases (4 HL, 2 atypical, 2 benign), whereas all ALCL were diagnosed as malignancies. However, correct diagnosis of non-Hodgkin lymphoma (NHL) was made in only two ALCL patients (2 NHL, 1 HL, 1 sarcoma, 4 malignancy without specific type). Overall, the percentage of large abnormal cells ranged from 30% to 90% in ALCL except for one case, whereas it was less than 5% in all 8 HL. A spectrum of atypical cells was more characteristic of ALCL. In contrast, HL showed an sharp difference between reactive lymphoid cells and neoplastic ones (bimorphic pattern). Moreover, the emergence of kidney-shaped abnormal cells or wreath-like multinucleated cells was helpful in diagnosing ALCL. The combination of thesefeatures would be useful in differentiating HL and ALCL. Nevertheless, these two types of lymphomas cannot be definitely distinguished based on cytomorphological features alone. Therefore, the aim of FNAC would be to suggest a specific diagnosis and indicate the need for a biopsy.

Primary colonic lymphoma is a rare disease and open surgical biopsy is usually necessary for hietological confirmation. Despite the submucosal location of the tumors, histological confirmation is frequently made by endoscopic multiple punch biopsies. Recently, three patients were admitted to the hospital with right lower guadrant abdominal pain, mass and abnormalities in the right colon and cecum on the barium enema. We performed colonoscopy and found smooth surfaced polypoid mass with occasional shallow ulcerations without lobulation, so suspected lymphoma endoscopically but failed to confirm histologieal diagnosis by usual punch biopsy. Thereafter, all three cases were undergone to laparntomies, and two were confirmed to be non-Hodgkins lymphoma and the other was Hodgkins disease. Here, we present those three cases of endoscopically found colonic lymphoma with review of literatures.

Burkitt's lymphoma is a type of non-Hodgkin's lymphoma occurring predominantly in children. In some cases, the first manifest site is the jaw, and the disease may be misdiagnosed as an infectious disease. A case of a 12-year-old boy with a painful swelling on the right retromolar triangle area is presented. At the time of the first visit, it was misdiagnosed as an osteomyelitis. Included are several characteristics and differential diagnosis of this disease.

CT findings of 19 kidneys in 12 patients with renal and perirenal non-Hodgkin's lymphoma were retrospectively reviewed to determine distinguishing characteristic and specific findings. CT manifestation of the renal and perirenal lymphoma included multiple nodules in five kidneys(26.3%), trans-capsular infiltration in three kidneys(15.8%). trans-sinus infiltration in nine kidneys(47.4%) and diffuse infiltration in two kidneys(10.5%0. Perirenal changes were thickening of the renal fascia in ten kidneys(52.6%) and crescentic lesion of low attenuation in the subcapsular area in five kidney(26.3%). Retroperitoneal lymphadenopathy was evident in eleven patient(57.9%). Renal calyceal dilatation without renal pelvic dilatation(selective calcelal dilatation) was noted in three kidneys. Familiarity with these CT findings of renal and perirenal lymphoma may be helpful in the diagnosis and management of patient with non-Hodgkin's lymphoma.

A case of primary malignant lymphoma of the brain is described in which lesions seen on computed tomography scans disapperared and clinical remissions occurred by the administration of corticosteroid. In our patient, at least three remissions occurred over a span of about 44 months. The diagnosis was delayed because of easy disappearance and confusion with other conditions. A stereotactic biopsy was performed and diagnosed as Non-Hodgkin's lymphoma, diffuse, large noncleaved cell type, B cell origin by H & E and immunologic marker analysis. We present our case with review of the literatures.
