In the setting of a nonhealing, chronic wound, it is advisable to send a skin biopsy for histopathologic examination to rule out malignancy. Skin biopsies may also be beneficial to rule out other differential diagnoses such as calciphylaxis, vasculitis, and venous stasis. The wound biopsy can be incisional, excisional, or performed via punch biopsy.
