—The ophthalmologist is often confronted with a patient having a periocular or facial skin lesion that is suspected of being malignant. The proper management of these lesions requires a biopsy and histopathologic examination. An incisional biopsy can be easily accomplished with a punch biopsy technique that is widely used by our dermatology colleagues. The ease of obtaining a good specimen, the uniform nature of the tissue obtained, and the simplicity of wound closure lends itself to use in the ophthalmologist's office.Disposable punches come in various sizes, ranging from 1 mm to 10 mm in diameter (Fig 1). The 3-mm or 4-mm punch is best suited for periocular or facial lesions. The punch biopsy is performed after intradermal or subcutaneous injection of local anesthesia and proper skin preparation with povidone-iodine (Betadine) solution. The punch is placed perpendicular to the lesion and gentle vertical pressure combined with a
