    Skeletal muscle - Hemorrhage in a male F344/N rat from a chronic study. Erythrocytes and circulating leukocytes are present surrounding individual muscle fibers.
    Skeletal muscle - Hemorrhage in a female B6C3F1/N mouse from a chronic study. In this longitudinal section, erythrocytes are present between muscle fibers.
    Skeletal muscle - Hemorrhage in a male F344/N rat from a chronic study. Large lakes of erythrocytes surround a large bundle of muscle fibers, some of which are fragmented.
    Skeletal muscle - Hemorrhage in a male F344/N rat from a chronic study. Macrophages containing golden-brown pigment are present within a region of chronic hemorrhage.
