(A) Right Ear 2. Organ of Corti. There is an extensive focal area of epithelial damage in the inner ear, and an intense subepithelial inflammatory response affecting the bone. It is composed of a large number of degenerated neutrophils, lymphocytes, and a few macrophages, with edema, fibrosis, debris, and fibrin. (B) Left Ear 2. Organ of Corti. There is an extensive focal area of epithelial erosion in the inner ear, primarily affecting the endosteum. There is a zone of necrosis with abundant degenerated neutrophils, a smaller number of macrophages with foamy cytoplasm, abundant debris, fibrin, and moderate fibrosis
