title: [Typing of amyloidoses intra vitam by tissue biopsy using antibodies. Report on 2 patients].
abstract: The value of the immunohistochemical classification of amyloid-syndromes has been illustrated in two patients with generalized amyloidosis. Chemical types and exact diagnosis were recognized in biopsies (and later necropsies) using antisera against different purified amyloid fibril proteins and the indirect immunoperoxidase technique. The first case, originally diagnosed as "perireticular" amyloid, was diagnosed as "Ak-amyloidosis with kappa-Bence-Jones-proteinuria without apparent B-cell malignoma", the second case as "AA-amyloidosis reactive to periodic fever". The diagnosis and possible therapeutic measures are discussed in the light of the new classification of amyloid syndromes.
