[Renal tumors in children, excluding Wilms' tumor. Apropos of 29 cases]

Abstract

The authors present a multisource study of 29 kidneys tumors (Wilms excepted) in children. The most common types (18 cases) are tumors from metanephrogen blastema (congenital mesoblastic nephroma, nephroblastomatosis and nodular renal blastema, multilocular cystic nephromas. Mature kidney tumors are much more rare in childhood (8 cases): they are epithelial tumors (adenoma or adenocarcinoma) or mesenchymal neoplasms. In one case, histological study don't permit to list a malignant tumor to one of previous categories. Finely, among secondary tumors, two localisations of hemopathy are reported. After a limited exposure of cases and review of the literatures the authors emphasize the anatomo-clinical aspects, the value of paraclinical exams and the treatment of each type of tumor.
