SILICON CARBIDE EMBEDDED IN SKIN
A
61-year-old Oriental man with a diagnosis of coccidiomycosis was seen for dental examination. Peculiar cutaneous lesions of a blue coloration were noted to be evenly distributed over the face and palmar surfaces of the hands. Intraoral examination was not remarkable, and a Panorex radiograph was within normal limits. However, periapieal radiographs revealed spotty granular radiopacities of questionable etiology. An interview with the patient revealed that at

one time he attempted to make a diamond by fusing silicon carbide (Carborundum) under high temperature and pressure. The explosion that occurred permanently embedded fragments of the material in his skin. Carborundum is most commonly used in grinding wheels, abrasive papers, solutions, and pastes. Similar radiographic findings of spotty granular radiopacities have been reported in patients with multiple sebaceous plugs and chronic acne. Xtephevz R. Fved, D.D.S.
