Cutaneous Silica Granuloma

Abstract
Cutaneous silica granuloma is a rare and fascinating cause of delayed scarring. Symptoms may arise many years after minor wounding if glass, sand, or other silica-containing particles have been embedded. Such granulomatous lesions are often nodular, indurated, and erythematous. They may respond to surgical excision or medical treatment, and in rare cases, they may spontaneously regress. We present one case in which three separate areas of cutaneous silica granulomas developed after a latent period of about 20 years and then involuted without intervention. The etiology and therapeutic options are discussed.
