Long-term recurrence of primary amyloidosis of the bladder

An 84-year-old man presented to our department with a recurrence of a primary amyloidosis of the bladder 14 years after the first diagnosis. Follow-up had been stopped 5 years after the first procedure because no cystoscopic anomalies were noted. General evaluation confirmed the diagnosis of primary amyloidosis. The lesions were endoscopically resected. At the 3-year follow-up, the patient was free of symptoms and had remained cystoscopically free of disease. However, stable amyloidosis deposits have always been noted on the computed tomography scans. This case emphasizes the necessity of a longer follow-up, including computed tomography of the pelvis, during the 10 to 15 years after the first occurrence of the disease.
