Abstract

Background: Melanosis vesicae is a rare condition characterized by the deposition of melanin within the bladder urothelium.

Case presentation: We present a case of a 72-year-old male with a history of recurrent urinary retention, bladder diverticula, and concurrent Aerococcus urinary tract infection who presented with left-sided abdominal pain. Cystoscopy revealed diffuse black splotch lesions throughout the bladder and two diverticula. Histopathological examination confirmed the diagnosis of melanosis vesicae. The patient ultimately underwent an open bladder diverticulectomy.

Conclusion: The potential associations between melanosis vesicae, urinary tract malignancies and concurrent conditions such as bladder diverticula and urinary infections warrant further investigation.
