title: Primary amyloidosis with high grade transitional cell carcinoma of bladder: a rare case report.
abstract: Primary amyloidosis of bladder is a rare disease that closely resembles bladder cancer on clinical presentation with painless gross hematuria. Pathologically this is a totally benign non-neoplastic lesion and its association with urothelial carcinoma of the bladder is rare. We herein report a 64-year-old diabetic male who has been treated for primary amyloidosis of bladder for the last 26 years presented recently with high-grade solid urothelial cancer with osseous metaplasia and sarcomatoid change of bladder with area of amyloid deposition.
