Bladder Melanosis

This case report describes a rare cystoscopic finding in an octogenarian, presenting initially with nonspecific lower urinary tract symptoms. Physical examination did not reveal any abnormal skin or mucoepi-dermoid pigmentation. Routine ultrasound identified cystic changes in the bladder prompting cystoscopic investigation. Flexible cystoscopy identified melanin deposits within the bladder mucosa, and biopsy subsequently confirmed a diagnosis of bladder melanosis. The authors of this report wish to add to the available literature on this extremely rare finding in the hope a more robust evidence base would allow a protocol to be established for follow-up. The ultrasound findings reported in this study have not been previouslyreported and may benefit future guidelines on diagnosis.
