The most common tumors that may be misclassified as papillary RCCs are the following: metanephric adenoma, epithelial-predominant nephroblastoma
, (33) clear cell RCC with prominent papillary growth pattern, clear cell papillary RCC, and translocation RCC.
The differential diagnosis of cystic tumors includes non-neoplastic cystic renal diseases, multilocular cystic RCC, sarcomatoid RCC and nephroblastoma
. In multilocular cystic RCC, clear cell conglomerations are found on the cyst wall and blastema is found in nephroblastoma
Multilocular cyst of the kidney (cystic nephroma) and cystic, partially differentiated nephroblastoma
. Terminology and criteria for diagnosis.

It mainly includes peritoneal mesothelioma, melanoma and nephroblastoma
and majority of tumors are round to oval or subcutaneous masses (Goldsmith and Hendrick, 2002; Donelly, 1975).
Different types of pediatric renal tumors are known, the commonest of which is Wilms tumor or nephroblastoma
, other less common tumors are nephroblastomatosis, rhabdoid malignant tumor, clear cell sarcoma, congenital mesoblastic nephroma and multilocular cystic nephroma3.
Malignant epignathus including a nephroblastoma
component and successful management.
Formalin-fixed paraffin-embedded tissue samples from nine patients with RCC and two patients with nephroblastoma
were subjected to mRNA in situ hybridization and indirect immunofluorescence staining.
This group consists of Ewing sarcoma, PNETs, rhabdomyosarcoma, synovial sarcoma, non-Hodgkin's lymphoma, retinoblastoma, neuroblastoma, hepatoblastoma, nephroblastoma
, small cell osteogenic sarcoma, Wilm's tumor, and desmoplastic small round cell tumor.
Childhood renal neoplasm accounts for approximately 7% of all cancers in childhood and are in the vast majority Wilms' tumor (WT) or nephroblastoma
This pediatric renal tumor (also called Wilms tumor or nephroblastoma
) can be associated with numerous congenital anomalies which can occur as isolated entities or within well-defined syndromes (Beckwith Wiedemann, Denys-Drash, Perlman, Simpson-Golabi-Behmel, and WAGR syndromes) [20-27].
