Almost all Wilms’ tumor(9 cases, 82%) and all of neuroblastoma were found to occur under 6 years of age. In sex incidence, male and female ratie 1.5:1. 4)The incidence of malignant tumor was 67.5% (23 cases). 5)The other tumor were gastrointestinal polyposis, teratoma and hydronephrosis(3 cases in each), lymphosarcoma and adrenal tumor(2 cases in each) and hepatoblastoma, gastric cyst, pancreatic cyst, and ureterocele respectivaly. 6)The tumors of urogenital origin were 15 cases〔44%), adrenals 8 cases C23%)» gastrointestinal tract 6 cases, ovaries 2 cases, and sympathetics, omentum, liver and pancreas one respectively. 7)The cardinal symptoms and signs were abdominal masses (83%) and pain (40%). 8)Of the 26 retroperitonial tumors, the left site involvement was 15 cases, as compared to 9cases of right site and the remaining one was bilateral involvement.
