Skin necrosis following digital wart intralesional injection of cantharidin

Year: 2024

Type: article

Abstract: A right-hand-dominant female presented 5 weeks following a right middle finger intralesional cantharidin injection for a common wart by a dermatologist. The patient experienced progressive stiffness, blistering, swelling, pain, and ultimately, full-thickness skin necrosis surrounding the injection site. Careful debridement followed by a full-thickness skin graft was performed with no evidence of involvement of the germinal matrix or terminal extensor tendon. At the 7-month postoperative mark, the patient's graft exhibited favorable healing and improved functionality that did not require further follow-up. Intralesional injection of cantharidin solutions for digital warts leads to progressive skin necrosis. Our case required prompt debridement and defect coverage. Involvement of the underlying anatomical structures was also a concern. Dermatologists and hand surgeons should be familiar with this complication as intralesional cantharidin injections are contraindicated.
