    Skin Cancer Biopsy & Surgery

    Skin cancer surgery can be very complex or very simple. Dr. Kloss performs many skin procedures for both benign (non cancerous) and cancerous (malignant) skin lesions.

    Sun exposure and family history effects the risk of skin cancer in us all. A changing lesion (color, size growth, shape or texture) needs surgical attention and we can often perform a biopsy under local anesthesia right here in the office. For larger or more complex lesions surgery in the operating room may be necessary.

    Once the results of the biopsy come back from the pathologist (inspects the skin lesion under the light microscope) we can determine if any other treatment is necessary. For instance, basal cell skin cancer can be completely rescected whereas melanoma may need lymph nodes biopsied in addition. Dr. Kloss is board certified and very skilled in the evaluation and surgical care of a variety of skin lesions.
    ABOVE: Basal Cell skin cancer of the ear ABOVE: Pigmented Seborrheic Keratosis (benign) but difficult to distinguish from melanoma; If they grow, change in color or size, or bleed and if they are bigger than 4mm it is safest to have them biopsied.
    ABOVE: Benign, pyogenic granuloma. This is an inflammatory, wet, bloody lesion that results from some trauma. It usually grows quickly, is wet and bloody. It appears concerning, but is benign. ABOVE: Seborrheic keratosis. Benign. Look out for changes in size, color, bleeding, or size greater than 4 mm.
    ABOVE: Actinic Keratosis. Suspicious for Squamous Cell skin cancer, but on final pathology, it was benign. Resecting this is a challenge due to its size and location on the face. See the postoperative picture below! ABOVE: Pigmented seborrheic papillary keratosis. This is in need of biopsy. The nonpigmented lesion below is innocent and doesn't need a biopsy unless it is changing.
    ABOVE: The skin lesion is completely removed. This advancement flap heals very nicely with no downward distortion on the lower eye lid.
