Localized amyloidosis of the ureter is a relatively rare condition. We report a case of primary localized ureteral amyloidosis. A 66-year-old man was referred to our hospital complaining of right flank pain and gross hematuria. From the right hydronephrosis and irregular margin of the right lower ureter seen on the anterograde pyelography, we could not rule out a right ureteral malignancy. Total nephroureterectomy was performed and histologic examination showed ureteral amyloidosis. Amyloid was classified immunohistochemically as Alambda type. After all examinations for secondary or systemic amyloidosis were negative, primary localized amyloidosis of the ureter was confirmed.

A 46-year-old female was referred to our hospital with a complaint of left flank pain. Ultrasongraphy and computed tomography demonstrated a left hydronephroureter due to stenosis with a ureteral mass in the left lower ureter. Retrograde pyelography revealed severe stricture of left lower ureter and brushing cytology showed papanicolaou class III. Ureteral tumor was suspected and left nephroureterectomy with partial cystectomy was performed. Histopathological diagnosis was amyloidosis of the left ureter. There was no evidence of secondary or systemic amyloidosis. Finally, we diagnosed her with localized amyloidosis of the left ureter. Localized amyloidosis of the ureter is a relatively rare condition, and this is the 55th case reported in the Japanese literature.

Amyloidosis is a rare disease defined by accumulation of extracellular amyloid systemically or within a specific organ. Localized amyloidosis of the genitourinary system is extremely rare, with the predominate location being the bladder. The imaging findings are often nonspecific and mimic urothelial carcinoma. We present a 49-year-old woman with a chief complaint of flank pain. A filling defect was discovered on radiological imaging. The defect was subsequently biopsied and proven to be a primary amyloidosis of the renal pelvis. We then review the radiological findings of amyloidosis of the genitourinary system.

Localised amyloidosis in the urinary tract is a rare and often benign condition, which is usually clinically mistaken for malignancy. I this case report, a 48-year-old man was referred to the hospital with left flank pain, and CT-urography showed a tumour with calcification in the distal ureter. During transurethral procedure, the tumour was resected macroscopically. Histology revealed the diagnosis of amyloidosis. Follow-up was without signs of systemic involvement or recurrence. This case underlines the significance of preoperative diagnostic biopsy, thus saving the patient from unnecessary major surgery.
