Abstract
Most silica-contaminated wounds of the skin heal without complications. Cutaneous silica granuloma is a poorly understood, uncommon condition resembling a sarcoidosis. We report a case of silica granuloma after intermittent intramuscular injections. A 70-year-old man presented a painless mass in his right buttock for 2 weeks. He had received intermittent intramuscular injections of antihistamine drugs due to chronic dermatitis for 30 years. The histolopathological findings showed numerous hyalinized collagenous nodules with concentric layers, and an ill-defined chronic granulomatous inflammation containing foreign material. A polarized light microscopic examination revealed birefrigent particles. The presence of silica components was confirmed by scanning electron microscopy and energy dispersive X-ray microanalysis.
