Skin-Sparing Marginal Excision: Case Report of a Novel Approach to Dystrophic Calcification

Abstract

Dystrophic calcification (DC) is a rare manifestation of calcium salt accumulation in non-skeletal tissues, often associated with local tissue damage. This case report presents a 45-year-old female patient who manifested soft-tissue calcification in an extra-articular burn scar, developing after a substantial latency period of 40 years. The conventional treatment, wide excision with skin grafting, was declined by the patient due to cosmetic and socioeconomic reasons. Instead, a skin-sparing marginal excision was performed. A thorough removal of the calcified lesions were achieved while conserving the overlying skin to reduce tension, a trigger factor of DC. Histopathological examination revealed fibrous tissue intertwined with DC. With a stringent follow-up regimen and routine X-ray examinations, no recurrence was observed over a period of 3 years. The patient expressed satisfaction with her expedited recovery and minimal postoperative scarring. This case underscores the potential of skin-sparing marginal excision as a viable alternative to wide excision and skin grafting, providing satisfactory outcomes and minimizing the risk of recurrence in patients who adhere to regular follow-up and examination schedules. However, more comprehensive research with a larger sample size is required before establishing this method as a standard treatment protocol for DC.
