[Case of AL amyloidosis associated with a remarkable histological progress in a short period].

AL amyloidosis is the most common form of systemic amyloidosis. Although kidney biopsy often is the method by which the disease is identified, small amounts of amyloid in kidney biopsy specimens may be missed on routine examination unless specifically investigated. We present here a previously healthy 60-year-oldmissed on routine examination unless specifically investigated.
