A Rare Case of Hematuria; Primary Amyloidosis of the Bladder Neck.

Primary and localized amyloidosis of the urinary tract is considered to be a rare clinical entity with approximately 160 cases documented in the literature. Here we present a case of a 77 year old gentleman with painless visible hematuria. Flexible cystoscopy revealed abnormal and polypoidal bladder mucosa. Transurethral resection of these lesions revealed histology with congo-red staining and positive green-apple birefringence, these findings are consistent with amyloidosis. There has so far been no sign of recurrence in this gentleman, with routine cystoscopic surveillance. Here we present a literature review on the presentation, diagnosis and management of this rare condition.
