anonymous Amyloidosis. 100% Confirmed by Congo red stain.  100
anonymous senile cardiac amyloidosis (70%) dilated cardiomyopathy (30%) The following special stains to be performed: Congo Red stain to highlight amyloid deposits salmon red and use polarise light to demonstrate APple green birefringence. Massons Trichome stain to highlight interstitial fibrosis.  100

anonymous Amyloidosis (100%) To confirm by Congo Red stain.  100
anonymous amyloidosis nil  100
anonymous Amyloidosis 100% This can be confirmation with Congo red or crystal violet staining.  100
anonymous A form of degenerative / infiltrative "cardiomyopathy". Need to consider amyloidosis. - Amyloidosis can be confirmed by Congo red stain. - However, the patchy pattern of involvement and lack of vasculopathy is unusual for amyloidosis. If Congo red is negative, need to consider differential diagnosis including toxicity (e.g. catecholamine or drug-induced cardiomyopathy). Suggest detailed clinical history, and EM study may be indicated. - Unlikely to be ischaemic or infective processes.  100
anonymous Senile cardiac amyloidosis nil  100
anonymous Amyloidosis. Probability : 100% Confirmed by Congo red stain.  100
anonymous Amyloidosis 100% Confirm by congo red stain; senile systemic amyloidosis has to be considered.  100
