“…Polypoid protrusions of the tumor into the pelvicaliceal system may occur, but parenchymal masses usually exist. Nine cases of botryoid Wilms tumor have been reported in the literature, including six cases associated with underlying parenchymal lesions [2][3][4][5][6][7]. Botryoid Wilms tumors without parenchymal lesions, similar to our patient, were detected in only three patients.…”

“…An asymptomatic mass is the most-common manifestation of typical Wilms tumor, with other manifestations occurring in less than 25% of cases. However, macroscopic hematuria has been frequently observed in botryoid Wilms tumor and usually assists with the diagnosis [2][3][4][5][6]. We present a patient with botryoid Wilms tumor whose initial laboratory findings were proteinuria and microhematuria.…”

“…Hence the symptom of gross hematuria should raise the suspicion of tumor extending into the collecting system. Passage of tumor per urethra occurs due to dislodged fragment of necrotic tumor tissue [4]. As in our case, it should raise suspicion of tumor extension into the ureter or bladder.…”

“…Intrapelvic Wilms' tumour is extremely rare, and the exact incidence is not known. On rare occasions it arises from the renal pelvis and produces a polypoid growth resembling botryoid sarcoma [22][23][24][25][26], and the diagnosis is almost always made after surgical intervention. To our knowledge, 28 cases of intrarenal pelvic Wilms' tumours, including our case, have been reported to date [22,23,25,27].…”

“…Our patient possessed two anomalies (left esotropia and hypoplasia of the right third rib), which have not been reported previously. The preoperative diagnosis of botryoid Wilms' tumour may be difficult, due to its rare incidence and unusual presentation, since the botryoid tumour is prone to extend into the ureter [25,26,32]. Hydronephrosis with or without infection is likely to be an important presenting manifestation of Wilms' tumour.…”
