title: Relapsing polychondritis. An ultrastructural study of elastic and collagen fibres degradation revealed by tannic acid.
abstract: In a case of relapsing polychondritis, ultrastructural study of ear cartilage using tannic acid staining showed patterns of degradation of elastic and collagen fibres. The participation of macrophages and chondrocytes in the resorption of ear cartilage is discussed.
