Fig 1 Brown-black granules coat dermal elastic and collagen fibers (A) and basement membrane of eccrine sweat glands (B). An adjacent ill-defined aggregate of histiocytes contains numerous crystalline, silica fragments (C). (Hematoxylin-eosin stain; original magnification: A, B, and C ×600.)

Fig 2 A, Dark field microscopy reveals small, white, refractile granules deposited on elastic and collagen fibers. B, Scanning electron microscopy demonstrates small particles on elastic and collagen fibers. C, Energy-dispersive spectroscopy identifies the particles as minute fragments of silver and copper and confirms admixed silica. (A, Hematoxylin-eosin stain; B and C, unstained slides; original magnifications: A, ×400; B, ×1500.)
