“…However, with the adoption of this term for every case exhibiting multiple primary congenital cysts in the substance of one or both kidneys, the following major varieties of polycystic kidneys can be distinguished: [1][2][3][4][5][6][7] Polycystic Kidneys of Infantile Type.\p=m-\ In this well-defined group, multiple and very small cysts which are densely packed together replace the whole renal parenchyma of both kidneys almost completely; the kidneys are greatly enlarged; polycystic disease in other organs such as the liver, the pancreas, and the lungs almost constantly coexists; and patients die within the first few days of postnatal life.…”

Cystic nephroma: a case report and review of the literature

“…Similarly, in adults (as in our case) the order would be CN, multilocular cystic renal cell carcinoma and cystic renal cell carcinoma. Generally, it is believed that CN is malformation that enlarges by fluid accumulation and cystic dilatation of individual locules and present as tumor-like cystic mass [ 12 ]. Some investigators suggested this entity to be classified among the mixed epithelial stromal tumors, while others consider it as a separate entity [ 13 ].…”

Papillary Adenocarcinomatous Degeneration Occurring in a Multilocular Renal Cyst

“…In fact the small number of cystic nephroblastomas reported (Landing, 1958;Uson ei al., 1960;Boggs et al, 1965;Christ, 1967;Fowler, 1971;Behr and Duari, 1975;Datnow and Daniel, 1976) do not show recurrence even without radiotherapy. For this reason some authors have suggested that These facts lead us to consider multilocular cysts as a dysgenetic anomaly of the metanephric blastema and of the mesoderm included in the renal blastema, a true hamartomatous lesion as proposed by Arey (1959).…”
