Patient 5: Hematoxylin and eosin stain of the left capsule showing patchy loss of cellular staining with loss of nuclei, indicative of necrosis. This produced a ‘washed out’ staining appearance. This tissue was paucivascular and fibrotic and the presence of fibrinoid necrosis of the collagen was suggestive of mechanical abrasion and increased pressure applied to the capsule from the pocket. This led to compression of vasculature and an anoxic state (original magnification ×100)
