Plasma col1 leukemia with motility-related morphological behavior is rarely studied. The plasma cells have variable degrees of cytoplasmic morphologies as dairy Projections, long extensions and pseudopods. These morphological evidences show the papa bility of wide spread and dissemination of disease itself. We present a case of a 38 year old woman who had back pain for 4 months and was diagnosed as a solitary plasmacytoma of the third lumbar vertebra. In spite of resection of the tumor and chemotherapy, the plasmacytoma was disseminated into both breasts and ovaries within less than a year. On her blood examination, we counted 34% of plasma cells in peripheral blood and 91.6% of plasma cells in bone marrow aspiration. Most of them resealed hairy projections and pseudopods of the cytoplasm.

BACKGROUND: The purpose of our study was to evaluate the functional and radiologic outcomes of additive augmentation sutures through rotator cuff for proximal humeral fractures stabilized locking plate in elderly patients. METHODS: We enrolled 74 patients over the age of 60 years who received internal fixation using locking plates for proximal humeral fractures. Of these, 50 patients had additive augmentation sutures through rotator cuff. The mean age at the time of surgery was 72.1 years (range, 60-89 years), and the mean follow-up period was 17.5 months (range, 12-62 months). The humeral neck-shaft angle and humeral head height were used as radiological markers to assess the effect of additive augmentation sutures through rotator cuff. We allocated the patients who received additive augmentation sutures into group A and those who did not into group B. RESULTS: At the final follow-up, the mean Korean Showlder Society score and Constant scores were 88.96 +/- 12.1 and 86.6 +/- 11.9, respectively, in group A and 86.21 +/- 11.8 and 85.3 +/- 11.7, respectively, in group B (p=0.368, 0.271). At the final follow-up, the mean loss in humeral neck-shaft angle from the time of immediate postoperative measurement was 1.6degrees in group A and 4.8degrees in group B, whereas the mean loss in humeral head height was 0.82 mm in group A and 0.52 mm in group B (p=0.029, 0.178). CONCLUSIONS: The surgical outcomes of internal fixation using locking plates for proximal humeral fractures were clinically and radiologically good in elderly patients over the age of 60 years without any observable complications. Further, the loss of humeral head shaft angle at the final follow-up from its initial postoperative measurement was significantly smaller in patients who received an additive augmentation suture than in those who did not. Thus, we conclude that augmentation sutures are a beneficial option for elderly patients that clinicians can consider at the time of surgical decision making.

PURPOSE: We compared the contrast enhancement patterns of hepatocellular carcinomas(HCC), hemangiomas, and metastasis on two phase imagings to determine the value of two phase dynamic CT in the differential diagnosis. MATERIALS AND METHODS: Two phases spiral volumetric CT scan were obtained 45 seconds and 6 minutes after bolus injection of contrast material in 106 patients. A bolus of 100 mL of nonionic contrast material was administered intravenously at a injection rate of 2 mL/sec. RESULT:In Hepatocollular carcinoma, 47% were totally hyperdense and 30% were totally hypodense in early phase, and 82% were totally hypodense in late phase. In hemangioma, 90% were peripherally hyperdense in early phase, 52% were isodense and 27% were totally hyperdense in late phase. In metastatic liver malignancies, 65% were hypodense and 32% were peripherally hyperdense in early phase, and 79% were hypodense in late phase. CONCLUSION: Two phases spiral volumetric CT scaning is considered to be heplful in the differential diagnosis of hepatic tumors.

PURPOSE: It's well known that the Epstein-Barr virus (EBV) is associated with endemic Burkitt's lymphoma and B cell lymphomas in immunocompromised individuals, and undifferentiated carcinoma of the nasopharynx. A clonotypic proliferation of EBV has been demonstrated in the neoplastic cells of these malignancies, suggesting a causative role of EBV in the tumorigenesis. More recently, it was identified that EBV has been linked to Hodgkin's disease and B or T-cell non-Hodgkin's lymphomas (NHLs) without preexisting immunodeficiency. MATERIAL AND METHOD: To determine the immunophenotype and incidence of EBV infection in sporadic NHLs of Korea, We investigated 90 cases of NHLs through immunohistochemistry and polymerase chain reaction, respectively. RESULTS: Sixty-nine of 90 (77%) of NHLs are of B-cell type, 18 of 90 (20%) of NHLs are of T-cell type and 3 out of 90 (3%) of NHLs are undefined lineage by immunohistochemistry. EBV genome was detected in 7 out of 69 (10%) B-cell lymphomas, 5 out of 18 (28%) T-cell lymphomas and 1 out of 3 (33%) non-B and non-T cell lymphomas by polymerase chain reaction. The male/female ratio of EBV-positive NHLs was 2.25:1. There are no prominent differences in age distribution and tumor localization between EBV- positive groups and negative groups. CONCLUSION: EBV positivity in T-cell NHLs is rather higher than in B-cell NHLs and this finding suggests that there is inter-relation association between EBV and T-cell NHLs, although the exact nature of this association remains to be established.

PURPOSE: Transforming growth factor beta1 (TGF-beta1) inhibits the growth of bladder cancer cells and this effect is prominent and constant in 253J bladder cancer cells. We performed a microarray analysis to search for genes that were altered after TGF-beta1 treatment to understand the growth inhibitory action of TGF-beta1. MATERIALS AND METHODS: 253J bladder cancer cells were exposed to TGF-beta1 and total RNA was extracted at 6, 24, and 48 hours after exposure. The RNA was hybridized onto a human 22K oligonucleotide microarray and the data were analyzed by using GeneSpring 7.1. RESULTS: In the microarray analysis, a total of 1,974 genes showing changes of more than 2.0 fold were selected. The selected genes were further subdivided into five highly cohesive clusters with high probability according to the time-dependent expression pattern. A total of 310 genes showing changes of more than 2.0 fold in repeated arrays were identified by use of simple t-tests. Of these genes, those having a known function were listed according to clusters. Microarray analysis showed increased expression of molecules known to be related to Smad-dependent signal transduction, such as SARA and Smad4, and also those known to be related to the mitogen-activated protein kinase (MAPK) pathway, such as MAPKK1 and MAPKK4. CONCLUSIONS: A list of genes showing significantly altered expression profiles after TGF-beta1 treatment was made according to five highly cohesive clusters. The data suggest that the growth inhibitory effect of TGF-beta1 in bladder cancer may occur through the Smad-dependent pathway, possibly via activation of the extracellular signal-related kinase 1 and Jun amino-terminal kinases Mitogen-activated protein kinase pathway.

PURPOSE: Transforming growth factor-beta1 (TGF-beta1) plays a dual role in apoptosis and in proapoptotic responses in the support of survival in a variety of cells. The aim of this study was to determine the function of TGF-beta1 in bladder cancer cells. MATERIALS AND METHODS: The role of TGF-beta1 in bladder cancer cells was examined by observing cell viability by using the tetrazolium dye (MTT) assay after treating the bladder cancer cell lines 253J, 5637, T24, J82, HT1197, and HT1376 with TGF-beta1. Among these cell lines, the 253J and T24 cell lines were coincubated with TGF-beta1 and the pan anti-TGF-beta antibody. Fluorescence-activated cell sorter (FACS) analysis was performed to determine the mechanism involved after TGF-beta1 treatment in 253J cells. RESULTS: All six cell lines showed inhibited cellular growth after TGF-beta1 treatment. Although the T24 and J82 cell lines also showed inhibited cellular growth, the growth inhibition was less than that observed in the other 4 cell lines. The addition of pan anti-TGF-beta antibodies to the culture media restored the growth properties that had been inhibited by TGF-beta1. FACS analysis was performed in the 253J cells and the 253J cells with TGF-beta1. There were no significant differences in the cell cycle between the two treatments. However, there were more apoptotic cells in the TGF-beta1-treated 253J cells. CONCLUSIONS: TGF-beta1 did not stimulate cellular proliferation but was a growth inhibitory factor in bladder cancer cells. However, the pattern of its effects depended on the cell line. TGF-beta1 achieved growth inhibition by enhancing the level of apoptosis.

PURPOSE: To evaluate the CT features of abdominal tuberculosis by the pattern anaylsis. MATERIALS AND METHODS: We retrosepctively reviewed the CT findings of confirmed abdominal tuberculosis in 16 patients. Of the 16 patients, 1 was man and the remaining 15 were women with an average age of 34.1 years and the highest incidence in the twenties of age. Intravenous and oral contrast agents were used in all patients. The amount and location of ascites and the changes in the omenturn, mesentery, bowel wall, and peritoneum were analyzed. The morphologic feature, size and main compartment of involvement were also evaluated in the cases with lymphadenopathy as well as other changes in intraabdominal organs. RESULTS: The abdominal tuberculosis was more common in the female(15/16, 93.8%) and could be classified into 3 patterns on their CT findings;Complex ascitic, lymphadenopathy, or abscess forms. The complex ascitic form(10/16, 62.5%) was most commonly seen and characterized by uneven distribution and Ioculation of intraperitoneal fluid collection and marked changes of the omenturn and mesentery. The lymphadenopathy form(3/16, 18.8%) was characterized by central low density and peripheral rim enhancement on postcontrast CT with common involvements of porta hepatis and upper abdominal and paraaortic lymph nodes. The abscess form(3/16, 18.8%) was mainly related to the pelvic abscesses. CONCLUSION: CT was valuable in analyzing the patterns of the lesions and making a diagnosis of abdominal tuberculosis.
