[New method of differential histological diagnosis of different forms of amyloidosis]

A new method for morphological diagnosis of various forms of amyloidosis based on the use of a hot buffered hexamine-silver solution is suggested. Its potentials are illustrated on 37 cases of primary, hereditary, and secondary human amyloidosis as well as experimental amyloidosis. The proposed method permits morphological differential diagnosis of amyloidosis in those cases where other methods failed to do it.
