She had had undergone a traffic accident 6 months before, and the normally healed wound on her cheek became reddish and infiltrated. A Skin biopsy specirinen obtained from her skin lesion showed a foreign body reaction with histiocytes and numerouse crystalline structures. These particle. were birefringent under polarized light microscopy. Scanning electron microscopy revealed numerous crystalline particles. Energy dispersive x-ray analysis of the crystal revealed a sharp peak representing silia.
