Capillary hemangioma of the bladder in a pediatric patient.

We report a case of a bladder hemangioma in a pediatric patient. A 2-year-old Caucasian female presented with intermittent gross hematuria and protrusion of beefy red tissue near the vaginal introitus when straining. On cystoscopy, we discovered a wide-based vermiform mass. Transurethral resection of the bladder mass was performed. Based on the histological findings of the tissue resected, a diagnosis of capillary hemangioma of the bladder was made. Despite their rarity, bladder hemangiomas should be considered in the differential in children with gross hematuria.

Pedunculated and obstructive Wilms' tumor: A rare presentation in a 2 year-old male.

Wilms' tumor manifesting as an obstructing ureteral mass is extremely rare. Herein, we report an unusual case in which a child presented with a clinical picture concerning for and suggestive of ureteropelvic junction obstruction (UPJO), but was instead found to have an intrapelvic pedunculated Wilms' tumor with extension into the proximal ureter. We discuss the patient's diagnostic workup, radiographic, operative and pathologic findings, as well as important lessons learned from this unusual case.
