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.

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.

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.

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.

PURPOSE: Laparoscopy-assisted distal gastrectomy (LADG) has gained wide acceptance for minimally invasive treatment of early gastric cancer (EGC). The aim of this study was to see the relationship between the operative approach of a distal subtotal gastrectomy and food retention of the remnant stomach. METHODS: A retrospective review of the records of 321 consecutive patients with gastric cancer who underwent a distal subtotal gastrectomy between 2001 and 2008 was conducted. A total of 233 patients who revisited the same surgeon's outpatient clinic and received regular endoscopic examination using the same protocol were finally included in this study. Reconstruction was performed using the Billroth I procedure. Mechanical-stapled anastomosis (MSA) was performed in 112 patients and conventional hand-sutured anastomosis (HA) was performed in 121 patients. RESULTS: According to results of multivariate analysis, the anastomosis method (MSA) was the only independent risk factor for accumulation of food residue. At six and 12 months after surgery, the incidence of food retention was higher in patients who had undergone MSA (22.3%, 13.4%) than in those who had undergone HA (9.1%, 2.5%) (p=0.006, p=0.002, respectively). However, the incidence of food residue at 24 months after surgery did not differ statistically between MSA and HA (p=0.266). CONCLUSION: Our results showed that the laparoscopic approach was not influenced on the accumulation of food residue. Mechanical-stapled anastomosis was the only independent risk factor for food retention. During the early postoperative period, although more food retention was observed in patients who underwent MSA than in those who underwent HA, in the long term, this anastomosis method did not influence food retention after a distal gastrectomy.

PURPOSE: We studied 278 men who are over 40 years of age to educate BPH and to evaluate the prevalence of BPH in Busan city of Korea. MATERIALS AND METHODS: Between December 1997 and February 1998, 278 men in Busan city were investigated. The screening tests included urinary symptom questionnaire (IPSS), digital rectal examination (DRE), prostate specific antigen (PSA) and uroflometry. RESULTS: Based on the IPSS, 36.3%, 49.7% and 14.0% of the men were mild (1-7), moderately (8-19) and severely (20-35) symptomatic. The mean maximal flow rate and PSA for men 40 to 49, 50 to 59, 50 to 69 and over 70 years old were 18.4 ml/sec, 14.2 ml/sec, 12.9 ml/sec, 10.6 ml/sec and 1.081 ng/ml, 1.195 ng/ml, 1.527 ng/ml, 2.352 ng/ml respectively. CONCLUSIONS: The prevalence rate of clinical BPH(IPSS>7 and peak urinary flow rate<10 ml/sec) in community-based study of 278 men was 25.5%.
