history & physical
■80% of non-melanoma skin cancers
■Increasing incidence with age; most >40 years of age
■Usually begins as a small, slow-growing, waxy, semi-translucent nod-
ule with central depression and telangiectasia
■May appear as reddish eczematous patch (superficial type) an irreg-
ular pigmented nodule (pigmented type) or as a waxy white sclerotic
plaque (morphea or sclerotic type)
■Most often on head, neck and other sun-exposed areas of fair-
skinned individuals with light-colored hair and eyes
■Ulceration, crusting and bleeding on slight injury common
■Usually history of extensive sun exposure, also seen in old burn scars,
vaccination sites, previous x-ray treatment areas, immunosuppres-
sion and chronic arsenic exposure
■Genetic and congenital factors: basal cell nevus syndrome (Gor-
lin syndrome), Bazex syndrome, albinism, epidermolysis bullosa
dystrophica, nevus sebaceus of Jadassohn and xeroderma pigmen-
