Calcium salt deposits in the presence of normal calcium/phosphorus metabolism involving tissues that do not physiologically calcify are referred to as dystrophic calcification. The condition may be associated with a variety of systemic disorders. Additionally, injured tissue of any kind is predisposed to dystrophic calcification. The case of a 21-year-old man with two isolated dystrophic calcifications in the right masseter muscle is presented. Dystrophic calcifications should be studied carefully and differentiated from lesions resulting from other syndromes that manifest calcification of soft tissues. The lack of a classification system of soft tissue calcifications complicates the management and study of the condition. Schlagwörter: calcification, choristoma, dystrophy, masseter muscle
