Clinical Presentation of Skin Cancers
While the appearance of any one skin cancer can vary, there are general physical presentations that can be used in screening. Basal cell carcinomas (BCCs) most commonly have a pearly rim or can appear somewhat eczematous. They often ulcerate. Squamous cell carcinomas (SCCs) frequently have a thick keratin top layer. Both BCCs and SCCs are associated with a history of sun-damaged skin. Melanomas are characterized by asymmetry, border irregularity, color variation, a diameter of more than 6 mm, and evolution (ABCDE criteria). Photographs representing typical clinical presentations of these cancers are shown below.
