Problemic issues in Molecular Characterization, Risk of Progression and Recurrence of Basal Cell and Squamous Cell Carcinomas of the Skin

Non-melanoma skin tumors are a fairly common. Squamous cell carcinoma of the is characterized by particularly high malignancy, which due to ability metastasize. However, it has also been shown that patients with basal have an increased risk developing squamous carcinoma. The molecular phenotype these tumors, as well markers progression, not studied. There no clear opinion about origin although assumed both them common progenitor cell, namely, cells appendages carcinoma, and epidermis In current literature, there only sparse conflicting data on non-melanoma their progression. addition, correlation between dermoscopic histopathological characteristics nonmelanocytic need be studied in detail, particular progression recurrence tumors. Correlation can reveal valuable information. Therefore, important study phenotypic use assess mentioned diseases.
