What is ABCD mean in the study of skin?
The recently described ABCD rule of dermatoscopy (skin surface microscopy at x10 magnification), based on the criteria asymmetry (A), border (B), color (C), and differential structure (D), improved diagnostic accuracy when applied retrospectively to clinical slides.
What are the ABCD signs that a spot on the skin may be melanoma?
The ABCDEs of melanoma
- A is for Asymmetry. Most melanomas are asymmetrical. …
- B is for Border. Melanoma borders tend to be uneven and may have scalloped or notched edges, while common moles tend to have smoother, more even borders.

What does the ABCD rule stand for in recognizing skin cancer?
The ABCD (Asymmetry, Border, Color, and Dimension) criteria represent a commonly used clinical guide for the diagnosis of early melanoma.
What is the ABCD rule?
The Skin Cancer Foundation and the American Academy of Dermatology recommend using the ABCD method (see photos above) to help detect melanoma: A (most early melanomas are asymmetrical); B (borders of melanomas are uneven); C (color; varied shades of brown, tan, or black are often the first sign of melanoma); and D ( …
What does ABCD mean in examination of pigmented areas?
The ABCD (asymmetry, border irregularity, color variegation, diameter >6 mm) acronym was created in 1985 to help primary care physicians and laypersons recognize early melanomas that might be confused with benign pigmented lesions.
What is the ABCD rule for determining the presence of melanoma?
The ABCD acronym was devised in 1985 by Kopf and colleagues39 to help patients recognize several clinical features of melanoma: asymmetry, border irregularity, color variation, and diameter (>6 mm).

ABCDE stands for asymmetry, border, color, diameter and evolving. These are the characteristics of skin damage that doctors look for when diagnosing and classifying melanomas. Asymmetry – Melanoma is often asymmetrical, which means the shape isn’t uniform.
What does the acronym Abcde stand for?
The underlying principles are: Use the Airway, Breathing, Circulation, Disability, Exposure (ABCDE) approach to assess and treat the patient.
What is lentigo maligna?
Lentigo maligna (LM) and lentigo maligna melanoma (LMM) are types of skin cancer. They begin when the melanocytes in the skin grow out of control and form tumors. Melanocytes are the cells responsible for making melanin, the pigment that determines the color of the skin.
Which type of skin cancer can be recognized in the lesions character based on the ABCD rule?
The ABCDE rule, first introduced in 1985 as the ABCD rule3 and then expanded in 2004 to the ABCDE rule,4 encompasses several clinical features of melanoma, including Asymmetry, Border irregularity, Color variation (both intralesional color variation as well as a color that is different from the patient’s other nevi), …
What are the 3 types of skin cancer?
Skin cancer — the abnormal growth of skin cells — most often develops on skin exposed to the sun. But this common form of cancer can also occur on areas of your skin not ordinarily exposed to sunlight.
