핵심 개념

• Melanoma — Melanoma is a malignant tumor originating from melanocytes, known for its high metastatic potential and being the most deadly form of skin cancer, often related to UV exposure.
• ABCDE criteria — The ABCDE criteria are a mnemonic tool used in dermatology for early detection of melanoma, including Asymmetry, Border irregularity, Color variation, Diameter >6mm, and Evolving changes.
• Diameter — In the context of melanoma diagnosis, diameter refers to a lesion larger than 6mm, which is a key indicator in the ABCDE criteria suggesting a higher risk of malignancy.
• Breslow depth — Breslow depth measures the vertical thickness of a melanoma in millimeters from the granular layer of the epidermis to the deepest point of invasion, crucial for staging and prognosis.
• Dermoscopy — Dermoscopy is a non-invasive skin imaging technique that uses magnification and lighting to visualize subsurface structures, aiding in the differential diagnosis of pigmented lesions like melanoma.
