Histological Findings:

Haematoxylin & Eosin (x400)
Examination of the tissues around the joint revealed
destruction of the apparent architecture of the vascular walls. Instead
there may be seen concentric thickenings of the vessel walls and narrowing
of the lumens. Some vascular walls have been replaced by a pale pink amorphous
material (consistent with the deposition of fibrin).The special stain
shows fibrin as an amorphous yellow colour.

Special Stain (x40)
This is an example of what type of necrosis?
