[Pediatric retroperitoneal tumors].
The author has based his work "Retroperitoneals tumors in infancy and childhood" in 65 cases observed at "Hospital Martagao Gesteira", Salvador, Bahia, Brasil. 32 of the retroperitoneals tumors, either intrarenals or extrarenals, observed in infancy and childhood were Wilm's tumor, 22 neuroblastoma, 5 hydronephrosis, 2 multicystic kidney, 1 policystic kidney, 2 pancreatic cyst and 1 biliar cyst. Wilm's tumor had the highest incidence - 32 cases (49,2%); neuroblastoma was in the second place in incidence - 22 (33,8%) of the 65 cases of retroperitoneals tumors studied, were neuroblastoma. As registered by the author in previous paper, the neuroblastoma, on contrary of what is established in the specialized literature, not was: the most frequent abdominal tumors, in infancy and childhood, neither it was also the abdominal pediatric tumor which could match Wilm's tumor in incidence. The plain X ray film of the abdomen, the Excretory Urography, the Cavography and Arteriography, the Radiological Examination of the Stomach and Duodenum, of the Small Intestine and the Colons, contribute in a very important way to establish the topography (retro or intraperitoneal) of the pediatric abdominal tumors. The author emphasizes that the plain X ray film of the abdomen supply important elements for the conclusion concerning the localization of abdominal tumors, from the observation of a simple criterion - the retroperitoneals tumors obliterate the border of kidney, because they are placed in the same plan of the kidney, data which is not pointed out sufficiently by the authors who have studied the subject.
