Malignant fibrous histiocytoma of the bone is relatively rare than that affecting the soft tissue. The authors have first experienced a case of malignant fibrous histiocytoma affecting the distal tibia of thirty-two years old woman in Korea. We obtained good results from free vascularized fibular graft after radical resection in stead of amputation. A case of malignant fibrous histiocytoma of the bone is reported with brief review of literature.

The present study was intended to define the relationship of radiological findings and pathological types ofprimary lung cancer. The 85 cases were selected after confirmation of the cell types by bronchoscopic biopsy,cervical lymph node or thoracotomy biopsy and lung resection. Results of the study were presented below. 1.Primary lung cancer is frequently developed after 4th decade and males were affected more frequently than femaleswith ratio of 2 to 1. 2. The frequencies of pathologic cell types of lung cancer were presented as follows.Squamous cell carcinoma 40% Adenocarcinoma 25% Undifferentiated cell carcinoma 30% Alveolar cell carcinoma 5% 3.The findings of plain chest radiograph were presented as follows. In squamous cell carcinoma, hilar enlargement orhilar mass is the most frequent finding (53%) with atelectasis(26%) or obstructive pneumonitis(26%). Inadenocarcinoma, pleural effusion is accompained about half of cases (53%). In undifferentiated cell carcinoma,hilar mass with mediastinal widening and pleural effusion is frequent finding.

We managed the two cases of small cell carcinoma of prostate, which has been reported only 20 cases in the world literature. It has not been reported in our country. It`s prognosis is very poor and it may have neurosecretory manifestation. Small cell carcinoma of the prostate combined with adenocarcinoma or previous history of adenocarcinoma is found in 50% cases. The diagnosis was established by pathologic findings with special stain (neuron specific enolase) and electromicroscopic examination.

Incidence of adenocarcinoma of the kidney in long-term hemodialysis is higher than in the general group. Although renal cancers occuring in dialysis patients are often small and asymptomatic, some patients present with cutaneous, visceral, or skeletal metastasis. We report a case of adenocarcinoma of the kidney in chronic hemodialysis patient. A 36-year-old male was diagnosed as chronic renal failure 6 years ago and then had been recieving hemodialysis. Renal tumor and multiple renal cysts were incidentally found in right kidney by renal ultrasonography and abdominal CT scanning. Radical nephrectomy was done and pathologic diagnosis was renal cell carcinoma and multiple simple renal cysts.

Eosinophilic cystitis is characterized by an eosinophilic infiltration usually of all layers of the bladder wall, ranges from a mild form of cystitis to a chronic recurrent relentless inflammation which even may progress to the point of damaging the upper urinary tracts with deterioration of the renal function. The etiology remains unclear, and there is no specific therapy available. The tumoral form of eosinophilic cystitis is a rare phenomenon and characterized by an extensive bladder wall infiltration, that may clinically imitate an invasive bladder cancer. We report a case of eosinophilic cystitis appeared to be an invasive bladder cancer extending to the pelvic side wall in a 37-year-old female, who was treated with transurethral resection.

Testicular tumors were reported sporadically in Korea. Seminomatous germ cell tumor is the most frequent tumor in the testis and it is treated highly effectively with irradiation and/or chemotherapy according to stage. Herein we report a relatively rare case of seminoma developed in abdominal cryptorchid testis of 28 years old male. which was treated with PVB chemotherapy after cytoreductive surgery. Histopathological examination revealed seminoma of stage II B(T3N2MO) by M.D. Anderson hospital classification Postoperative PVB chemotherapy was performed and the tumor was completely remitted at follow up study for 4 years.

A few delayed epistaxis was reported, and it is an unusual complication of closed head injury. We experienced 2 cases of delayed epistaxis and monoocular blindness by cavernous vascular lesions(traumatic aneurysm and C. C. F.). We confirmed the vascular lesions by carotid angiography and Brain C. T. They were treated by carotid ligation and carotid ligation with embolization, and we mer with good results. We present 2 cases of the delayed epistaxis complicated by traumatic lesions of cavernous internal carotid artery, and also the literatures were reviewed.

Cyclosporine nephropathy was induced by intraperitoneal injection of cyclosporine 25 mg/kg in Sprague-Dawley rats daily for 1, 4, 8, and 12 weeks to clarify the relationship between cyclosporine nephropathy and the expression of TGF-beta1 with extracellular matrix deposition. On light microscopic examination, the kidneys in the 12 week cyclosporine-treated rats showed focal or striped fibrosis, vacuolization of tubular cells, and injury of endothelial cells. Immunohistochemically, TGF-beta1 protein was strongly expressed in the cyclosporine-treated rat kidneys, especially in the glomerular endothelial cells, interstitial endothelial cells, tubular epithelial cells, and parietal cells in the Bowman's capsule of the glomerulus as well as the periglomerular arterioles. The amount of TGF-beta1 expression was correlated with the morphological change in the cyclosporine-treated rats. Extracellular matrix, such as fibronectin and collagen IV, was also expressed in the endothelial cells of the glomerulus and the interstitium. It can be concluded, therefore that TGF-beta1 protein is probably involved in the early stage of fibrogenesis in cyclosporine nephropathy. It can be postulated that cyclosporine nephropathy results from the accumulation of extracellular matrix associated with the increase of TGF-beta1 transcription. Therefore, these results could be used in reducing fibrosis in cyclosporine nephropathy.
