Abstract
Introduction
Bladder localization of AA amyloidosis is rare. It can be responsible for massive and recurrent hematuria. We report a case of bladder AA amyloidosis secondary to Crohn's disease in a renal transplant patient.
Clinical observation
A 62-year-old man, suffering from Crohn's disease since 1991 complicated by renal AA amyloidosis. He received a kidney transplant since 20 years from an HLA identical donor. After an 18-year period of clinical remission, the patient was admitted for a flare-up of his Crohn's disease in the form of intermittent diarrhoea. Treatment with corticosteroids allowed a good evolution. A year later, he was rehospitalized for massive macroscopic haematuria. Histological examination of the bladder biopsy revealed AA amyloidosis. The patient fully recovered but died 6 weeks later from septic shock of urinary origin.
Conclusion
The treatment of bladder localization of AA amyloidosis is based on treating the cause. Hematuria is sometimes massive, exceptionally requiring emergency cystectomy for haemostasis.

Organe d''expression de la Société de Néphrologie, de la Société Francophone de Dialyse et de la Société de Néphrologie Pédiatrique, Néphrologie et Thérapeutique a pour vocation de publier des textes en français dans le domaine de la Néphrologie, qu''il s''agisse d''actualisation des connaissances, de recommandations de bonne pratique clinique, de publications originales, ou d''informations sur la vie des trois sociétés fondatrices. La variété des thèmes abordés reflète la richesse de la Néphrologie, qu''il s''agisse d''aspects fondamentaux issus de la physiologie, de l''immunologie, de l''anatomo-pathologie, ou de la génétique, ou de sujets de néphrologie clinique, notamment ceux en rapport avec les thérapeutiques néphrologiques, transplantation, hémodialyse et dialyse péritonéale.
