[Transitional cell tumor in a 12-year-old patient]

Area of Science:

• Urology
• Pediatric Oncology
• Pathology

Background:

• Transitional cell papillomas (TCPs) are common adult urinary tract neoplasms but rare in children.
• These epithelial tumors typically occur in the bladder, near ureteric orifices.
• Gross hematuria is the most frequent presenting symptom.

Observation:

• A 12-year-old girl presented with a transitional cell papilloma.
• The tumor was located near the right ureteric orifice.
• This case provides insight into a rare pediatric presentation.

Findings:

• Transitional cell papillomas are histologically low-grade tumors.
• Complete surgical excision is generally curative.
• High recurrence rates and potential for aggressive transformation are noted.

Implications:

• Early diagnosis and management are crucial for pediatric TCPs.
• Understanding the etiopathogenesis may improve treatment strategies.
• This case contributes to the literature on rare pediatric urinary tract neoplasms.
