title: [Digestive amyloidosis in generalized amyloidosis. Current data and practical applications (author's transl)].
abstract: Following a summary of the modern, biochemical classification of generalized amyloidosis into immunoglobulin-induced (AL) and non immunoglobulin-induced (AA), the authors study amyloid lesions of the digestive tract. The classical topographical data concerning primary and secondary amyloidosis are described. These data are confirmed by current studies based on the new classification and completed by a technique recently developed by Wright, where treatment of histological sections with potassium permanganate makes it possible to differentiate AL amyloidosis from AA amyloidosis. The resulting practical classification of amyloid deposits enables clinicians to form an idea of the aetiological group concerned. A study of rectal biopsies emphasizes the value of the results. The special cases of Portuguese amyloidosis and amyloidosis associated with Crohn's disease are also studied.
