We report the case of a 46-year-old man who initially presented with macroscopic haematuria. Although initially concerning for a malignancy in the bladder, histology demonstrated a primary bladder amyloidosis that has remained stable for 6 years since the initial diagnosis. Primary bladder amyloidosis is an important clinical entity that can mimic bladder malignancy on clinical history, radiological investigation and cystoscopic evaluation. Although uncommon, it should not be neglected as a possible diagnosis in patients presenting with haematuria.
