Cutaneous Melanoma Detection and Management

Skin aging is a progressive process in which environmental damage superimposed on aging skin determines the ultimate skin appearance. Intrinsic aging affects unexposed and exposed skin and is characterized by dryness, laxity, fine wrinkles, and skin atrophy. Among harmful environmental factors that contribute to extrinsic aging or photoaging, long-term effects of repeated exposure to ultraviolet (UV) light are the most significant and are referred to as photoaging. Photoaging affects the sun-exposed areas and is characterized clinically by fine and coarse wrinkling, roughness, dryness, laxity, and pigmentary changes. There is also an increase in development of benign and malignant neoplasms on photoaged skin.
