Congenital unilateral renal agenesis is a rare congenital anomaly. Furthermore, renal agenesis associated with neuroblastoma and cryptorchism is more rare in incidence. Recently we experieced a case of Rt. renal agenesis combined with cryptorchism and neuroblastoma. We diagnosed it with IVP and selective renal angiography and confirmed it with explolaparotomy and biopsy. We reviewed the literatures on renal agenesis, cryptorchism and neuroblastoma, and discussed possible embryological relationships between them and other combined congenital anomalies.

"We retrospectively reviewed the results of 1,850 fine needle aspiration cytology (FNAC) of thyroid nodules performed from 1990 to 1991 in the Department of Pathology, Seoul National University Hospital. Among 1,528 cases and 322 cases aspirated by clinicians and a pathologist, 465 cases (30.4%) and 13 cases (4.0%) of the aspirates were inadequate, respectively. In 227 cases, correlation of the FNAC diagnosis and histologic diagnosis was done. Excluding the inadequate cases, the sensitivity for the detection of neoplasm (malignancy together with follicular adenoma) was 86.4% and the specificity was 70.7%. The overall diagnostic accuracy was 79.0%. There were 16 false-positive cases (7.0%), and 19 false-negative cases (8.4%). The predictive value of each cytologic diagnosis was 92% in papillary carcinoma, and 100% in Hashimoto's thyroiditis. The expectancy of malignancy was 52.8% in ""suspicious malignancy"" and 26.7% in ""atypical lesion""."

In a group of 59 children with nephrotic syndrome who had been admitted to Severance Ho-spital, during the period of 2 years from July of 1978 till June of 1980, the histological picture seen on renal biopsy, the selective protein index, and the response to the steroid therapy were studied. The degree of selective protein index is not related to the total daily amount of urinary protein excretion and selective protein index remains relatively constant over months in the minimal lesion nephrotic syndrom. Those patients with primary renal disease and the nephrotic syndrome who displayed high selectivity types of proteinuria usually responds initially to steroid therapy within 8 weeks. Studies of selective protein index allow the pediatrician to avoid renal biopsy with safety in nephrotic children aged 1 to 5 years, but distinguish any given renal disease with certainty. The mesangial proliferative glomerulonephritis with immune deposits has relatively poor selectivity of proteinuria and without immune deposits, it has high or moder-ate selectivity of proteinuria. Response to treatment of steroid in the Henoch-Sch?lein Purpura was poor and not related with selective protein index.
