| pubmed-article:219577 | pubmed:abstractText | A renal tumour in a 4-year old girl morphologically appeared as both a nephroblastoma and, in parts, as a sarcoma botryoides of the renal pelvis. The histogenesis of this dysontogenetic tumour is most probably due to a disturbance of growth and differentiation both of the metanephrogenic blastema as well as partly of the urethral bud. This type of dysontogenetic tumour is extremely rare. Problems of diagnosis and operative therapy and the possibility of postoperative radiation therapy and cystostatic treatment are discussed. | lld:pubmed |
