Dystrophic Calcinosis Cutis Leading to a Nonhealing Wound in a Patient with Chronic Venous Insufficiency.

The presence of bony-appearing fragments and calcifications appearing superficially in a chronic, nonhealing wound raises suspicion for osteomyelitis. When radiological imaging and tissue biopsy of the lesion return negative for osteomyelitis, however, the differentials must be widened to successfully manage and heal a chronic wound. In this report, we discuss a case of an 80-year-old morbidly obese woman with a history of chronic venous insufficiency, hereditary hemochromatosis, and squamous cell carcinoma who presented to the wound clinic with a 5-month history of a nonhealing wound with bony-appearing fragments and calcifications on her left anterior leg status postbiopsy during routine skin examination. Upon clinical correlation with laboratories and imaging, it was determined that the cause of her nonhealing wound was due to dystrophic calcinosis cutis.
