PURPOSE: In vitro sonography of lymph nodes was performed to ascertain the differential point between benignancy and malignancy. MATERIALS AND METHODS: Ninty-one lymph nodes were obtained at gastric cancer surgery and pathologically proved as benignancy in 68 and malignancy in 23 cases. Sohographic and pathologic correlation of resected ninty one lymph nodes was done in terms of size, the ratio of longest diameter versus shortest diameter, central hyperechogenicity, and peripheral cortical echo. RESULTS: Sonographic findings of benign lymph node were small size, oval shape(85%), narrow central high echogenicity(44%), and symmetric cortical thickening(41%). Sonographic findings of malignant lymph node were large size, round contour(39%), loss of central high echogenicity(82%), and diffuse increase of cortical thickness(82%). CONCLUSION: The most reliable sonographic criterion for differentiation of benignancy from malignancy was size of a lymphnode.

Leydig cell tumor of the ovary is a very rare tumor which usually occurs in the postmenopausal age, and which is frequently associated with virilization. It has been classified as a lipid cell tumor due to the presence of intracytoplasmic lipids. However, since up to 25% of these tumors contain little or no lipid, the new term "steroid cell tumor" is proposed for this type of neoplasm. We report a case of Leydig cell tumor of the ovary in a 16 year old girl. The patient exhibited recently recognized hirsuitism and secondary amenorrhea. Physical examination revealed moderate obesity with moderate amounts of coarse hair over the whole body and a deepening of the voice. Testosterone and dehydroepiandrosterone sulfate levels were markedly elevated in the peripheral blood. Pelvic ultrasonography revealed a right ovarian tumor. The resected ovary showed a well demarcated, golden yellow to orange colored solid mass, measuring 7 cm on the cut surface. Microscopically, the tumor was composed of solid and diffuse sheets of tumor cells having abundant eosinophilic cytoplasm, and large round nuclei with frequent crystalloids of Reinke in the cytoplasm. To our knowledge this is the first case of Leydig cell tumor of the ovary in a young girl in the Korean literature.

The infantile polycystic kidney disease is rare fetal urinary tract anomaly. It is inherited with an autosomal recessive pattern and recurrence rate is 25%. The gene locus is on chromosome 6p. The pathogenesis of infantile polycystic kidney is the primary defect of the collecting ducts. The ultrasonographic finding of infantile polycystic kidney is oligohydramnios, bilaterally symmetrical enlarged kidneys with maintenance of their reinform shape. The differential diagnosis with adult polycystic kidney disease is important. The massive enlargement of the kidneys is rarely seen in adult polycystic kidney disease and the examination of the parents and other members of the family is helpful to confirm the adult polycystic kidney disease. If there is severe renal involvements, stillbirth or neonatal death secondary to pulmonary hypoplasia would be developed. If it were diagnosed before viability, termination of pregnancy is recommended. In a fetus at risk, diagnosed after viability, pregnancy termination is also recommended since this condition is uniformly fatal. We present a case of infantile polycystic kidney.

Transitional cell carcinoma(TCC) of the urinary bladder shows marked heterogeneity in biological behaviors. Evidence has accumulated that biological markers may provide significant information to predict the potential aggressiveness of TCC. We have assessed the expression of the epidermal growth factor receptor (EGF-R), c-erbB-2 and p53 proteins in 56 cases of TCC to investigate the prognostic significance of differential expression of these oncoproteins using an immunohistochemical method. We analysed the expression patterns of these oncoproteins according to tumor stage and grade. And we assessed the probability of progression-free survival in stage T1 tumors according to their expressions. Positive rates of EGF-R (>+3 staining intensity), c-erbB-2 (intense membrane staining) and p53 proteins (>20% positive cells) were 73.2%, 37.5% and 42.9%, respectively. Invasive tumors had significantly higher positive rates of all three factors than did superficial tumors (p<0.005 for EGF-R and c-erbB-2, p<0.05 for p53). High grade tumors had significantly higher positive rates of c-erbB-2 and p53 proteins (p<0.005). In superficial tumors, T1 tumors had higher positive rate of p53 protein compared with Ta tumors (p<0.05). Twelve cases of superficial tumors (34.3%) were positive for EGF-R and negative for c-erbB-2 and p53 proteins. Nine cases of superficial tumors(25.7%) were negative for all three factors. In invasive tumors, however, 42.5% of the cases were positive for all three factors. The overexpression of p53 protein was the only useful marker to predict the rapid progression in stage T1 tumors (p<0.05, log-rank test). These results suggest that the differential overexpression of EGF-R, c-erbB-2 and p53 proteins could be useful to depict tumor aggressiveness of TCC of the urinary bladder. And, the overexpression of a p53 protein may be a useful marker to predict the possibility of rapid progression in stage T1 tumors.
