Invasive Squamous Carcinoma and Adenocarcinoma of an Unreconstructed Exstrophic Bladder with HPV Infection.

Bladder exstrophy is a complex abnormality and is traditionally treated within the early years of life. It is associated with an increased risk of bladder cancer, with 95% of the arising tumors being adenocarcinomas and 3 to 5% being squamous cell carcinomas. HPV infections are also associated with an increased risk of bladder cancer. This case represents a patient with bladder exstrophy that gave rise to coinciding squamous cell carcinoma and adenocarcinoma. Final pathology results showed an infection with HPV. We presented the management of the case and discussed the diagnosis and treatment methods for this patient.
