Multiloculated Cystic Renal Tumors of Childhood: Has the Final Word Been Spoken.

Background:Multicystic renal tumors which include cystic nephroma, cystic partially differentiated nephroblastoma (CPDN) and cystic Wilms tumor has been a diagnostic and therapeutic challenge. Histopathological examination has been the only reliable differentiating method. Management of these tumors is still riddled with controversy as a definitive preoperative differentiation between the three has not been possible.Methods:A retrospective evaluation was performed of the treatment strategies employed with nine cases of multicystic renal tumors treated from 2005 to 2015.Results:The median age at presentation was 12 months with all except one being boys. All except two children underwent primary surgery. The median follow-up was 50 months with six children having long-term survival. One child succumbed to the disease process, one died due to an unrelated cause and another was lost to follow-up. Although there was no ambiguity with cases of cystic nephroma (CN) and cystic Wilms tumor, three of the four cases of CPDN had problems.Conclusion:Primary surgery for multicystic renal tumors is safe and should be seriously considered as it prevents overtreatment in cases of CN and early stage CPDN. Further studies are needed to fully understand the biological behavior of CPDN.

Adult benign multicystic nephroma: A diagnostic dilemma

Cystic nephroma, also called multilocular cystic nephroma, is a relatively rare, non-genetic, benign, unilateral renal multicystic lesion. The non-specific clinical findings and the paucity of information from imaging techniques make the preoperative dilemma from othercystic renal neoplasia; thus nephrectomy seems to be the most preferable treatment. We report a case of cystic nephroma in forty years male patient presented with asymptomatic lump in abdomen.

Nefroma cistico multiloculare

The authors review two cases of cystic nephroma, highlighting the present preoperative diagnostic possibilities and feasible choices of conservative surgery, even with foci of adenoma and nephroblastoma.

A Case of Cystic Nephroma

The authors describe an uncommon case of cystic nephroma. They define the histologic characteristics which lead to correct diagnosis, while showing how difficult preoperative diagnosis is (ultrasound, CT, angiography). They discuss treatment and affirm that nephrectomy is still the choice operation in relation to the potential malignity of the lesion.

Cystic nephroma

The clinical and pathologic findings of four cases of cystic nephroma (so-called "renal multilocular cyst") in four infants nephrectomized with the diagnosis of Wilms' tumor are presented. Each lesion consisted of an encapsulated mass composed of cysts separated by thin septa. Histologically the cysts were lined by epithelium, and the septa contained foci of immature metanephric blastema (abundant in one case and sparse in another). rhabdomyocytes and mature tubules. Neither embryonic ducts nor cartilage were seen. One cystic lesion was adjacent to a nephroblastoma which formed a separate nodule. No recurrences of metastases developed, and the only death was due to postoperative sepsis. These lesions are considered by some authors to be dysplasia, while others interpret them as benign neoplasms. Our findings and a review of the literature probably represent the differentiated counterpart of nephroblastoma.
