[Beta 2-microglobulin amyloidosis presenting as intestinal perforation in a haemodialysis patient].

Long term haemodialysis patient is subject to several complications such as generalised amyloidosis which is the result of deposits of beta2-microglobulin not depurated by haemodialysis. Digestive location causes ischemic accidents such as ulcer, infarctus, digestive haemorrhage, pseudo-obstruction and perforation manifested by a surgical emergency. Our observation is the 6th case of intestinal perforation caused by amyloidosis deposit reported in the literature.
