Secondary amyloidosis of the bladder causing macroscopic hematuria.
Bladder involvement in amyloidosis is unusual. The case of an 80-year-old man with macroscopic hematuria caused by secondary amyloidosis of the bladder is described. Cystoscopic examination revealed only a diffuse edematous area and bleeding. No tumor-like lesions were identified. Transurethral biopsy revealed amyloid deposits. Macroscopic hematuria disappeared spontaneously after cystoscopy and bladder biopsy. The patient has been followed up without treatment and is currently free of symptoms.
