Primary Amyloidosis of the Bladder / 대한비뇨기과학회지

ABSTRACT

Amyloidosis is a systemic disease characterized by the deposition of homogenous, eosinophilic and hyaline protein. Most cases of amyloidosis occur as a systemic disease, with a poor prognosis. Conversely, primary localized amyloidosis of the bladder has an excellent prognosis in most cases, it is, therefore, important to distinguish primary localized from systemic amyloidosis. Primary localized amyloidosis of the bladder is a rare disease, causing hematuria, which is often confused with bladder cancer. The diagnosis is usually made from a biopsy and subsequent pathological examination. We report a case of primary localized amyloidosis of the bladder, occurring in a 73 year old man, treated with a transurethral resection.
