Abstract

PURPOSE: Dystrophic calcification occurs in damaged or devitalized tissues in the presence of a normal calcium and phosphorus metabolism. There are many reports on dystrophic calcification caused by injections of various types of drugs. The aim of this report is to highlight the fact that dystrophic calcification can be caused by the injection of a foreign body for aesthetic augmentation.
METHODS
This case report describes a patient presenting with dystrophic calcification caused by an injection of an unknown foreign body approximately 50 years ago. An 80-year-old man had localized cellulitis with swelling and ulceration on the dorsum of the left hand. The radiographs demonstrated a 5x3.5x1.7 cm lesion between the first and second metacarpal bones and a 5x2.5x1.5cm lesion in the hypothenar region. The laboratory data and physical examinations were generally within the normal limits. The microscopic examination revealed dead bone fragments and dense collagenous tissue with dystrophic calcification.
RESULTS
After surgically removing the masses, the resulting defects were treated with an abdominal flap. The result was satisfactory in terms of symptoms and appearance.
CONCLUSION
This case suggests that dystrophic calcification can be caused by an injection of a foreign body for aesthetic augmentation.
