Fig.1 Basal-cell carcinoma
Basal-cell carcinoma (BCC), also named as basal-cell cancer, is the most typical type of skin cancer. It often displays as a painless raised area of skin, that may be shiny with small blood vessels running over it or it may display as a raised area with ulceration. Basal-cell cancer grows slowly and can be harmful to the tissue around it but is not commonly to spread to distant areas or lead to death. Around 60% of basal-cell carcinomas occur on sun-exposed areas of the body. About 30% occurs on areas of the body that are not exposed to sunlight, stressing the genetic susceptibility of basal-cell cancer. Morpheaform or Infiltrative basal-cell cancers can display as the scar tissue or skin thickening, thus making diagnosis difficult without using a skin biopsy and tactile sensation. Ki67 is a biologic marker of basal cell carcinoma.
