[Vesical amyloidosis. Apropos of a case and a review of the literature].

A case of primary localized amyloidosis of the bladder in a 60 years old male is described. The initial symptom was hematuria. Cystoscopy revealed a redish angioma-like lesion on the trigone, and the diagnosis was pointed out with biopsy, complementary data, and a close follow-up during two years. In the literature we found 47 cases of primary localized amyloidosis of the bladder and 10 others cases of amyloidosis of the bladder which were part of generalized amyloid disease. The interest of the Wright's special staining method is underlined specifying, on light microscopic study, the AA or AL type of the amyloid disease.
