Chapter 21 Vulvar Biopsy
Common indications
Vulvar lesions that are not identifiable as benign or that fail to respond to therapy should be biopsied for a definitive diagnosis and treatment (Figure 21-1).
Key steps
Punch biopsy instrument, small Adson’s forceps or pick-ups, small iris scissors, and a specimen jar can be used to sample these lesions. Lidocaine solution of 1%, with or without epinephrine, a syringe, and a 25-gauge needle will be necessary for anesthesia. Monsel’s solution and cotton-tipped applicators are usually sufficient for hemostasis (Figure 21-2).
Key steps
1. Anesthetize the lesion: If the patient is not allergic to iodine, clean the lesion with Betadine (Figure 21-3). Slowly inject 1 to 2 cc of lidocaine under the lesion, elevating it slightly (Figure 21-4).
