title: Botryoid Wilms' tumor: a case report and review of the literature.
abstract: Here, we report a new case of botryoid Wilms' tumor, a 4-year-old boy, who was referred to us with a chief complaint of dysuria and gross hematuria. The computed tomography and radical nephroureterectomy showed that a botryoid sarcoma-like appearance occupied the right renal pelvis and extended into the bladder. Histologic examination further confirmed this case was a mixed type of Wilms' tumor. In a word, we demonstrated a rare case of botryoid Wilms' tumor, which extended from the renal pelvis into the ureter and bladder, then some degenerative and necrotic tissue with calcification discharged from urethra. Postoperative adjuvant chemotherapy was executed. At 24-month follow-up, there was no evidence of recurrence.
