[Amyloidosis of the urinary tract--case report and review of the literature].

Amyloidosis is a systemic disease which affects a variety of body organs and systems, and is characterized with the deposition of hyalin, eosinophilic, protein-like material in the tissues. Primary amyloidosis of the urinary tract is an extremely rare localization and every published case report represents interest. The authors present a rare case of primary localized amyloidosis of the bladder, which mimics itself as a neoplastic formation and imposes significant diagnostic and therapeutic difficulties. The correct therapeutic approach and the exact histopathologic diagnosis has enabled us to preserve the bladder of the patient and to achieve optimal therapeutic results.
