Jason Y1 - 2021 N1 - T2 - The Atlas of Emergency Medicine, 5e AB - Melanoma is a potentially fatal cutaneous tumor derived from epidermal melanocytes. Any age can be affected; peak incidence is in 20- to 45-year-old patients (much younger than BCC or SCC). The most significant risk factor is a primary relative with melanoma. Evaluation of any pigmented lesion should include the ABCDE rule (A for asymmetry, B for irregular borders, C for color variegation, D for diameter > 6 mm, and E for elevation and evolving). Any lesion with these characteristics is considered suspicious for melanoma.
