Malignant fibrous histiocytoma is a rare malignant tumor of probably histiocytic origin. It is more common in soft tissue than bone. Usually it involves metaphysis or diaphysis of long bone. Primary spinal malignant fibrous histiocytoma is exceedingly rare. Authors report a case of primary malignant fibrous histiocytoma which showed rapid spinal cord compression in thoracic spine with review of literatures.

This study represents an attempt to present an analysis of early surgical results in 15 cases of aortic surgery conducted at Chonnam University Hospital between February 1994 to August 1995. The subject, 9 males and 6 females, ranged in age from 32 to 73 years with a mean age of 55.07+/-11.76 years. The patients were treated for dissecting aortic aneurysm in nine, atherosclerotic aneurysm in 4, and traumatic aortic aneurysm in two. There were 9 cases of median sternotomy, 4 cases of posterolateral thoracotomy, and 2 cases of thoracoabdominal incision. Graft replacement of ascending aorta and/or partial or total aortic arch were performed in 9 patients, descending aorta and/or thoracoabdominal aorta in 3 and total aorta in 1. Two traumatic aortic aneurysms were closed directly. Associate procedures were resuspension of aortic valve in three patients and elephant trunk procedure, coronary reimplantation and aortic valve replacement in one patient. Nine patients underwent operation for ascending aorta and/or aortic arch with retrograde cerebral perfusion during deep hypothermia and circulatory arrest. Perfusion pressure was maintained below 25 mmHg and the mean duration of circulatory arrest was 56.67+/-29.25 minutes. Three patients underwent graft replacement of desending thoracic and thoracoabdominal aorta during deep hypothermia and circulatory arrest. Three patients died of traumatic bile peritonitis, multioragn failure, and rupture of residual dissecting aortic aneurysm by malignant hypertension. Postoperative complications included reoperation for bleeding in 4 patients, temporary confusion in 3, pulmonary complication in 3, and pericardial effusion in 1.

Tubulointerstitial nephritis (TIN) is the most common form of renal involvement in IgG4-related disease. It is characterized by a dominant infiltrate of IgG4-positive plasma cells in the interstitium and storiform fibrosis. Demonstration of IgG4-positive plasma cells is essential for diagnosis, but the number of IgG4-positive cells and the ratio of IgG4-positive/IgG-positive plasma cells may vary from case to case and depending on the methods of tissue sampling even in the same case. IgG4-positive plasma cells can be seen in TIN associated with systemic lupus erythematosus, Sjogren syndrome, or anti-neutrophil cytoplasmic antibody-associated vasculitis, which further add diagnostic confusion and difficulties. To have a more clear view of IgG4-TIN and to delineate differential points from other TIN with IgG4-positive plasma cell infiltrates, clinical and histological features of IgG4-TIN and its mimickers were reviewed. In the rear part, cases suggesting overlap of IgG4-TIN and its mimickers and glomerulonephritis associated with IgG4-TIN were briefly described.

PURPOSE: Henoch-Shonlein purpura(HSP) is a systemic vasculitis that involves multiple organs, especially the kidney, which is the most important organ in determining the prognosis of the disease. The morbidity of HSP nephritis in adults is low and there have been little research done on its clinical course so far. Therefore, we have compared the clinical course of HSP nephritis in children and adults in Korea. METHODS: We retrospectively analyzed 81 cases of HSP nephritis in children younger than 15 years of age, and 25 cases of adults older than 15 years of age who were admitted to Yonsei University Medical College Severance Hospital from Jan. 1986 to May 2003. RESULTS: The male to female ratio was 1.5:1 in children and 1.3:1 in adults. The incidence of HSP nephritis for both age groups was found to be increased during the autumn and winter. Infection was the predisposing factor in 39 cases(48.1%) of children, 16 cases(64.0%) of adults, and drugs were the predisposing factor in 8 cases(9.9%) of children and 4 cases (16.0%) of adults. All patients initially presented with microscopic hematuria. Thirteen cases (16.0%) of children and 7 cases(28.0%) of adults initially showed proteinuria of nephrotic range. Thirty four cases(42.0%) of children and 4 cases(16.0%) of adults showed normal urinalysis after treatment. Asymptomatic urinary abnormalities were found in 41 cases(50.6%) of children and 18 cases(72.0%) of adults. Complications such as nephrotic syndrome and hypertension were found in 3 cases(3.7%) of children and 2 cases(8.0%) of adults. Three children(3.7%) and 1(4.0%) adult required dialysis or renal transplantation. Follow-up renal biopsies were performed on 21 children, of whom 10 cases(47.6%) did not show any histologic change, 9 cases(42.9%) showed low grade changes, and 2 cases(9.5%) showed high grade changes. Prognosis was gloomy when proteinuria of nephrotic range and high grade of abnormal histology were present at diagnosis, and there was no significant difference between the two groups(P<0.05) CONCLUSION: This study showed that there was no difference in terms of the clinical features and courses between the children and adults with HSP nephritis. Proteinuria of nephrotic range and the severity of abnormal histologic changes at diagnosis were found to be associated with a bad prognosis, therefore we recommend that patients with these features require long term follow-up and management.
