title: Carbon dioxide laser resection of a distal carpal pilomatricoma and wound closure using swine intestinal submucosa in a dog.
abstract: A carbon dioxide laser was used to incise around, dissect, and remove a 2-cm intradermal mass from the left carpus of an 8-year-old, spayed female wheaten terrier. The wound was partially closed, resulting in a 3-cm diameter circular defect with extensor tendons exposed. A swine intestinal submucosa graft was utilized to cover the remaining defect. The graft was removed 5 days later, revealing a healthy granulation tissue bed covering previously exposed tendons with minimal wound margin retraction. The remaining wound was allowed to heal by contraction and epithelialization that was complete by 5 weeks postoperatively. The mass, a pilomatricoma, had not recurred at the last follow-up contact 18 months after surgery. Pilomatricoma, laser application, swine intestinal submucosa grafting, and postoperative wound management are discussed.
