Summary
This report details a rare case of localized amyloidosis of the urinary bladder in an 82-year-old woman. Diagnosis was confirmed via biopsy, revealing amyloid deposition in the bladder wall without systemic involvement.
Area of Science:
- Urology
- Pathology
Background:
- Amyloidosis is a rare condition characterized by the deposition of amyloid proteins in various organs.
- Localized amyloidosis of the urinary bladder is an uncommon manifestation, often presenting with lower urinary tract symptoms.
Observation:
- An 82-year-old female presented with symptoms of micturition pain and urinary retention.
- Cystoscopy revealed a non-bleeding, broad-based lesion on the right lateral bladder wall.
- Histopathological examination confirmed amyloid deposition in the submucosal layer of the bladder.
Findings:
- The patient was diagnosed with localized amyloidosis of the urinary bladder.
- Biopsy and other examinations ruled out amyloid deposition in other organs.
- This represents the 23rd reported case in Japan.
Implications:
- This case highlights the importance of considering localized bladder amyloidosis in elderly patients with urinary symptoms.
- Transurethral biopsy is crucial for accurate diagnosis.
- The patient remained asymptomatic post-biopsy, suggesting a potentially conservative management approach.
