title: A rare case of localised AA-type amyloidosis of the ureter with spheroids of amyloid.
abstract: We present a case of localised AA-type amyloidosis of the ureter with spheroids of amyloid. Localised AA-type amyloidosis of the urogenital tract is uncommon and extremely rare as a cause of ureteric obstruction, with only two such cases described in the literature to date. Most previously described cases at this site are related to primary AL-type amyloidosis. Another interesting finding in this case is the presence of spheroids of amyloid, which to the best of our knowledge, has not been previously reported at this site, and is also unusual at other sites.
