MODEL RELEASED. Solar keratosis cryotherapy. Image 2 of 2. Liquid nitrogen has been applied to a solar keratosis on the ear of a 70-year-old man. The extreme cold of the liquid nitrogen (-198 degrees Celsius) freezes the keratosis,causing the white areas of dead tissue. The area will heal and the dead tissue will drop off. A solar keratosis,a pre-cancerous growth caused by sun damage,is usually removed in case it turns cancerous. For a sequence showing the treatment of this growth by cryotherapy,see images M729/042-043 | |
