Bilateral gluteal dystrophic calcification--a case report

Abnormal deposits of calcium in the injured and necrotic tissue (dystrophic calcification) are not considered to be rare conditions in human pathologic records. We report a severe case of bilateral gluteal calcification that has not often been found in the literature. It was caused by multiple intramuscular and/or subcutaneous injections. The multiple lumps along with the chronic unhealed fistula over the gluteal regions were successfully treated by carbon dioxide laser without recurrence. The pathogenesis of variable possibilities were reviewed and discussed.
