Adenocarcinoma in a Female Urethral Diverticulum With Gastric Differentiation: A Case Report.

This report describes a novel case of urethral adenocarcinoma in situ with enteric (gastric-type) differentiation in a 74-year-old female presenting with recurrent urinary tract infections and obstructive urinary symptoms. Magnetic resonance imaging (MRI) revealed a urethral diverticulum (UD), and a diverticulectomy was performed. Pathology from samples obtained during this operation revealed this rare subtype of malignancy. Our case highlights the importance of considering a broad differential diagnosis, even in patients with atypical presentations, and the need for further research to optimize the detection and treatment of this disease.
