The authors report a case of large malignant proliferating trichilemmal tumor of the scalp with calvarial destruction undergoing a successful staged operation to completely excise the tumor. The reconstruction of the scalp was delayed due to considerable amount of intraoperative blood loss and the negative pressure wound therapy was applied to the wound. The reconstruction with a free an anticoagulant thigh flap was subsequently performed 5 days later. Five weeks postoperatively, the patient had transient visual impairment from dural venous sinus thrombosis that was successfully treated with anticoagulation. On 1 year follow up, there was no evidence of tumor recurrence.
