Dystrophic Calcification of the Lower Leg in a Patient with Chronic Lower Extremity Venous Insufficiency and Diabetes Mellitus: A Case Report and Literature Review.

ABSTRACT: Chronic lower extremity venous insufficiency can cause local dystrophy, and some patients will develop calf dystrophic calcification. In this case report, the authors describe a patient with varicose veins of both lower extremities, venous insufficiency of the lower extremities, recurring ulcers on the left leg for more than 20 years, and diabetes mellitus with dystrophic calcification of the calf. The patient's left leg ulcer showed extensive chronic inflammation, pathological calcification, and necrosis of the subcutaneous tissue with a thickness of approximately 0.5 to 1 cm. The computed tomography, X-ray, and hematoxylin-eosin staining results confirmed calcification; the leg skin thickened because of inflammatory irritation. After 11 months of treatment, the calcified and necrotic calcification and necrotic tissue were removed, and the wound healed.
