Anatomo-clinical aspects of the basal cell carcinoma at the level of the cephalic end.

More than one third of all diagnosed cancer cases from all over the world are skin cancers, and the majorities are basal cell carcinomas. The incidence of skin tumors around the world is growing, the main concern being the increased frequency of skin tumors among young persons. Therefore, an early detection is required, starting with the general practitioner, dermatologist, oncologist, plastic surgeon and not least, the pathologist. We studied a sample consisting of 149 patients diagnosed with basal cell carcinoma at the level of the cephalic end and neck, all of them undergoing surgery--surgery individualized for each case. Some cellular and molecular modifications also resulted from infecting the cells with high carcinogenic risk HPV, considered by some scientists as responsible for the developing and progression of some neoplasias, including melanocytes and non-melanocytes skin tumors.
