A malignant granular cell tumor (MGCT) occurred in the left shoulder of a 62-year-old man. The patient underwent wide marginal excision followed by chemotherapy and radiotherapy. A metastatic tumor was identified in the axillary lymph node 22 months after the excision of the shoulder mass. The primary tumor was a poorly circumscribed mass measuring 5 5 4 cm. On cut section, it was a solid mass with yellowish tan color. Histologically, both primary and metastatic tumor consisted of polygonal cells with abundant granular cytoplasm and a vesicular nucleus with a prominent nucleolus. Two to three mitotic figures per ten high power fields at 200 were counted. Tumor cells were weakly stained with periodic acid-Schiff (PAS) preparation both before and after diastase digestion, and were positive for S-100 protein, neuron-specific enolase (NSE), and vimentin. By electron microscopy, the cytoplasm was filled with numerous autophagolysosomes containing myelin figures, mitochondria, and fragmented rough endoplasmic reticula. Basal laminae and angulated bodies were also noted. These findings suggest schwannian differentiation of this tumor.

We report a case of renal pelvic calcification and ossification simulating a renal pelvic stone. histopathological examination of resected kidney revealed submucosal calcification in the pelvic and ossified foci in the perivascular area. This is the first report in the Korean literature and have been reported 1 case in the English literature till now. This is very rare entity unrelated to amyloidosis.

We analyzed the results of the prostate biopsies of 64 patients with elevated serum PSA (>4ng/ ml) at Kangbuk Samsung Hospital from March 1993 to February 1996. Of 64 patients, 11 patients (17%) had prostate cancer and 53 patients (83%) were diagnosed as benign prostatic hyperplasia. Among the patients with prostate cancer, 1 patient had serum PSA between 4.1 to 10.0ng/ml, 2 patients between 10.1 to 20.0ng/ml and 8 patients above 20ng/ml The detection rates of prostate cancer in each serum PSA levels were 3%, 15% and 36% respectively. Two of 17 patients with both negative DRE and TRUS were diagnosed as prostate cancer Two of 21 patients with positive TRUS and negative DRE had prostate cancer but none of 8 patients with positive DRE and negative TRUS had prostate cancer. Seven of 18 patients with both positive TRUS and DRE had prostate cancer. The sensitivity, specificity, positive predictive value and overall accuracy of DRE and TRUS in patients with elevated PSA (>4ng/m1) were 64%, 64%, 27%, 64% and 82%, 43%, 23%, 50% respectively in patients with elevated serum PSA (>4ng/ml). In conclusion, these results suggest that prostate biopsy in early diagnosis of prostate cancer would be needed for the patients with elevated serum PSA (>4ng/ml) regardless of the results of DRE and TRUS.

Aortopulmonary fistula is an exceedingly rare vascular malformation. It is commonly derived after chest injuly or from complication of chest operation and aortic dissection and congenital aortopulmonary fistula is only several cases combined with Tetralogy of Fallot or aortic stenosis. But a congenital aortopulmonary fistula without any hemodynamic abnormalities was not reported. A 56-year old man with exertional dyspnea was admitted. In an examination on admission, there were no abnomalities. Aortography showed an aortopulmonary fistula that branches from the ascending aorta adjacent to the right coronary artery, running to the main pulmonary artery. Transcatheter coil embolization was performed and he was discharged 7 day after embolization without complication. Exertional dyspnea disappeared and careful follow up has be performed periodically.

The metastasis of renal cell carcinoma to ureter, urinary bladder and uterus are not common, only a few cases were reported. A 63 years old female was admitted to department of urology, Korea university hospital with intractable hematuria, vaginal bleeding and severe frank pain on left is side with abdominal distension. Herein we are presenting a case of metastatic renal cell carcinoma with review and literature.

A clinical observation was made on 239 cases of benign prostatic hypertrophy, admitted to the Department of Urology, Korea University College of Medicine during the period of 9 years and 8 months from Jan. 1972 to Aug. 1981. Following results were obtained. 1. Amount of residual urine from 10 ml to 1,500 ml with average 304 ml. 2. Hypertension in 35 cases (14.8%)and pulmonary diseases in 29 cases (12.1%)were frequently associated with B.P.H. 3. E.K.G. was performed in 171 cases. Abnormal findings included L.V.H. in 38 cases (22.2%), arrhythmia in 11 cases (6.4%), but normal in 118 cases (69%). 4. In blood chemistry, blood urea nitrogen was elevated in 75 cases (31.4%)and creatinine was elevated in 69 cases (28.9%). 5. The most common endoscopic findings were trabeculation in 214 cases (89.5%), inflammation in 192 cases (80.3%), kissing of lateral lobes in 138 cases (58.7%)and elevated interureteric ridge in 71 cases (29.7%). 6. Methods of operative treatment were T.U.R. in 184 cases, retropubic prostatectomy in 7 cases and suprapubic prostatectomy in 3 cases.

STATEMENT OF PROBLEM: Zirconia-based restorations have the common technical complication of delamination, or porcelain chipping, from the zirconia core. Thus the shear bond strength between the zirconia core and the veneering porcelain requires investigation in order to facilitate the material's clinical use. PURPOSE: The purpose of this study was to evaluate the bonding strength of the porcelain veneer to the zirconia core and to other various metal alloys (high noble metal alloy and base metal alloy). MATERIAL AND METHODS: 15 rectangular (4x4x9mm) specimens each of zirconia (Cercon), base metal alloy (Tillite), high noble metal alloy (Degudent H) were fabricated for the shear bond strength test. The veneering porcelain recommended by the manufacturer for each type of material was fired to the core in thickness of 3mm. After firing, the specimens were embedded in the PTFE mold, placed on a mounting jig, and subjected to shear force in a universal testing machine. Load was applied at a crosshead speed of 0.5mm/min until fracture. The average shear strength (MPa) was analyzed with the one-way ANOVA and the Tukey's test (alpha= .05). The fractured specimens were examined using SEM and EDX to determine the failure pattern. RESULTS: The mean shear strength (+/- SD) in MPa was 25.43 (+/- 3.12) in the zirconia group, 35.87 (+/- 4.23) in the base metal group, 38.00 (+/- 5.23) in the high noble metal group. The ANOVA showed a significant difference among groups, and the Tukey's test presented a significant difference between the zirconia group and the metal group. Microscopic examination showed that the failure primarily occurred near the interface with the residual veneering porcelain remaining on the core. CONCLUSION: There was a significant difference between the metal ceramic and zirconia ceramic group in shear bond strength. There was no significant difference between the base metal alloy and the high noble metal alloy.
