Transitional cell papillary bladder neoplasm in a girl: an unusual presentation

Area of Science:

• Pediatric Oncology
• Urological Pathology

Background:

• Transitional cell papillary bladder carcinoma is rare in children.
• Typical presentations involve urinary tract symptoms, often hematuria.

Observation:

• An 8-year-old girl presented with symptoms suggestive of acute appendicitis.
• Despite a normal appendix, abdominal pain persisted.
• No urinary symptoms or infections were detected.

Findings:

• Ultrasound revealed an intravesical tumor.
• Histology confirmed a low-grade, transitional cell papillary bladder carcinoma.
• This case represents an atypical presentation of pediatric bladder cancer.

Implications:

• Highlights the importance of considering rare diagnoses in pediatric abdominal pain.
• Suggests that bladder tumors can present without urinary symptoms.
• Underscores the need for comprehensive diagnostic workups in persistent abdominal pain.
