Basic Dermatology Curriculum (Videos)-How to Perform a Punch Biopsy

Video Transcription

Video Summary

The video explains the steps and equipment required for performing a punch biopsy. The equipment includes Q-tips, pick-ups, scissors, needle drivers, suture, tissue punch, gauze, alcohol swab, surgical marking pen, and appropriate wound cover. The area is cleansed and marked with a surgical pen. Anesthesia is administered using lidocaine with epinephrine, and the area is injected subcutaneously and intradermally. The biopsy is performed by applying downward pressure with a twisting motion using a punch. The core is removed and the wound is prepared for closure. Hemostasis can be achieved with various methods, including nylon sutures. Suturing is not recommended for infected or poorly healing skin.
