amyloidosis

large mass eosinophilic hyaline material dermis subcutis
-Accentuated deposition around deep vascular channels and adnexal structures
-Plasma cells large russel bodies at margins within amyloid islands
-FB Giant cells ,focal calcifications

2

amyoloidosis stains

crystal violet/ thioflavin T
congo/pagoda/scarlet red

keratin stains in amyloidsis

EAB903, EKH4

4

amyloid organ involvement

kidney heart liver, lichenified skin( kc degeneration)
