Transitional cell carcinoma in a single ectopic ureter opening into the ejaculatory duct

Area of Science:

• Urology
• Oncology
• Medical Genetics

Background:

• Ectopic ureters in males are uncommon congenital anomalies.
• These anomalies frequently present with associated renal dysgenesis and abnormal termination within the male reproductive tract.
• Malignant transformation within these non-functional urothelial systems is exceedingly rare.

Observation:

• This case report describes a male patient with a single ectopic ureter and a dysplastic kidney.
• The ectopic ureter terminated directly into the ejaculatory duct.
• The patient presented with primary transitional cell carcinoma arising from this ectopic ureteral system.

Findings:

• The study identifies the first documented case of transitional cell carcinoma originating in a male ectopic ureter.
• The tumor developed within a dysplastic kidney and a ureter terminating in the ejaculatory duct.
• This highlights a unique pathway for urothelial malignancy in a congenital anomaly.

Implications:

• This finding expands the understanding of rare urological malignancies.
• It suggests that ectopic ureters, even when non-functional, can undergo malignant transformation.
• Further investigation into the oncogenesis of ectopic urothelial tissues may be warranted.
