Basal cell carcinoma on the nose of a 79 year old female patient with Gorlin Chaudhry Moss syndrome. This patient had previously had a basal cell carcinoma excised from the same area. Basal cell carcinoma is the most common form of skin cancer among fair-skinned people. It mostly affects the elderly, although in recent years the average age of onset has steadily decreased. It usually appears on the face and is thought to be caused by the ultraviolet radiation in sunlight. It slowly destroys surrounding tissue, but seldom spreads to other parts of the body. Treatments for basal cell carcinoma include radiotherapy, cryotherapy, cauterisation and surgical excision.
