Fig. 83. Intracutaneous foreign material. In this case, injury was caused by the pressurized central material of a golf ball. The center of a standard golf ball is composed of barium sulfate and zinc disulfide compressed by overlying fibers of synthetic material. Foreign material can be identified in this histologic section of an eyelid. The tissue was removed during repair of the blast injury. (Hematoxylin-eosin stain; × 70.) Insets. Higher magnification shows that the material has been engulfed by macrophages. (Hematoxylin-eosin stain; nonpolarized and polarized, × 395.)
