Congo red-stained amyloid shows apple-green birefringence, sometimes called apple-green dichroism. Is this opinion correct? A cursory glance at published micrographs said to illustrate this color ...

Congo red staining with exhibition of an apple-green birefringence is diagnostic of amyloid. Immunohistochemistry can detect amyloid deposits but has limitations, and newer molecular techniques ...

This ultrastructure of the fibril allows the regular intercalation of Congo red dye, conferring a diagnostic optical property to amyloid such as apple-green birefringence under polarized light ...

Under the polarizing microscope, the stained amyloid protein appears apple green in color. This is called apple-green birefringence. Once the amyloidosis is confirmed by biopsy, the type of ...

Here, we describe a patient with renal amyloid A (AA ... silver staining), and apple-green birefringence is visible in the mesangium and along capillaries under polarized light (Panel D, Congo ...

However, only two related conditions are associated with the simultaneous presence of Bence Jones proteinuria and heavy albuminuria: renal AL amyloidosis and LCDD. [20] It is not uncommon for ...

Amyloid protein deposition can be seen as apple green birefringence upon microscopic examination. Iron deposition can be detected by biopsy, as well. Treatment is aimed at the primary etiology ...
