1. Airway, breathing, circulation, disability, exposure

Medical · Emergency Medicine Abbreviations

Structured primary survey used in trauma and critically ill patients to find and treat life threats in order. Disability refers to neurological status and exposure to fully undressing the patient while preventing hypothermia.

Central to ATLS and the UK Resuscitation Council approach. Each problem is treated as soon as found before moving on. In dermatology ABCDE is a different mnemonic for melanoma features.

2. Asymmetry, Border, Color, Diameter, Evolving (melanoma warning signs)

Medical · Dermatology Abbreviations

Mnemonic for features suggesting a mole may be melanoma: Asymmetry, irregular Border, uneven Color, Diameter larger than 6 mm and Evolving size, shape or color. It is widely used in public skin cancer education and self-examination.

Example: Mole on calf meets 3 ABCDE criteria (asymmetric, two colors, enlarging); excisional biopsy today.

The ABCD rule was introduced by dermatologists at New York University in 1985, and "E" for evolving was added in 2004. Some melanomas, especially nodular and amelanotic types, do not fit the rule. Dermatologists also use the "ugly duckling sign": a mole that looks different from a person's other moles.
