The term \u2018botryoid\u2019 describes an intrapelvic polypoid renal Wilms tumour, either extending from the renal parenchyma or primarily pelvis-based tumour. Both tumours filled the renal pelvis and extended down the proximal ureter, with no intraparenchymal tumour seen. Bilateral intralobar nephrogenic rests were present. Histological examination demonstrated triphasic nephroblastoma, with focal rhabdomyomatous differentiation of the stromal element bilaterally. Postchemotherapy, the patient underwent bilateral nephrectomy. Post complete resection of her bilateral disease, this patient has had an excellent outcome. This is only the third reported case of bilateral botryoid Wilms\u2019 tumour. While the condition is extremely rare, it should be included in the differential diagnosis of a young child with bilateral renal pelvic masses.<\/jats:p>","DOI":"10.1136\/bcr.02.2012.5854","type":"journal-article","created":{"date-parts":[[2012,9,7]],"date-time":"2012-09-07T08:03:33Z","timestamp":1347005013000},"page":"bcr0220125854","source":"Crossref","is-referenced-by-count":3,"title":["Bilateral botryoid nephroblastoma: a rare cause of renal failure"],"prefix":"10.1136","volume":"2012","author":[{"given":"Niamh","family":"Conlon","sequence":"first","affiliation":[{"name":"1Cellular Pathology Department, AMNCH, Tallaght, Dublin, Ireland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chia Wei","family":"Teoh","sequence":"additional","affiliation":[{"name":"2Nephrology Department, Our Lady\u2019s Children\u2019s Hospital, Crumlin, Dublin, Ireland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jane","family":"Pears","sequence":"additional","affiliation":[{"name":"3Paediatric Oncology Department, Our Lady\u2019s Children\u2019s Hospital, Crumlin, Dublin, Ireland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maureen","family":"O\u2019Sullivan","sequence":"additional","affiliation":[{"name":"4Histopathology Department, Our Lady\u2019s Hospital, Crumlin, Dublin, Ireland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2012,9,7]]},"reference":[{"key":"2025082804373201000_2012.sep05_2.bcr0220125854.1","doi-asserted-by":"crossref","unstructured":"Murphy WM Grignon DJ .
