==Overview==
==Overview==
Physical examination findings suggestive of [[malignant]] melanoma include ABCDE: <u>A</u>symmetry of the [[lesion]], <u>B</u>order irregularity, <u>C</u>olor change, large [[Diameter|<u>D</u>iameter]], and <u>E</u>volution over time.


==Physical Examination==
==Physical Examination==
Moles that are irregular in color or shape are suspicious of a malignant or a premalignant melanoma. Following a visual examination and a [[Dermatoscopy|dermatoscopic exam]] (an instrument that illuminates a mole, revealing its underlying pigment and vascular network structure), the doctor may biopsy the suspicious mole. If it is malignant, the mole and an area around it needs excision. This will require a referral to a surgeon or dermatologist.
===Skin===
*Although melanoma can occur anywhere, melanoma among women occurs more commonly on the [[Limb (anatomy)|extremities]], and among men it occurs more commonly on the [[trunk]] or [[head]] and [[neck]].
*[[Patient|Patients]] with suspected melanoma should have a full-[[Human body|body]] examination for other [[Lesion|lesions]].
 
*On [[physical examination]], the ABCDE for distinguishing [[benign]] [[Nevus|nevi]] from [[malignant]] melanoma are:

The diagnosis of melanoma requires experience, as early stages may look identical to harmless [[Mole (skin marking)|moles]] or not have any color at all. Where any doubt exists, the patient will be referred to a specialist dermatologist. Beyond this expert knowledge a [[biopsy]] performed under [[local anesthesia]] is often required to assist in making or confirming the [[diagnosis]] and in defining the severity of the melanoma.

Overview

Physical examination findings suggestive of malignant melanoma include ABCDE: Asymmetry of the lesion, Border irregularity, Color change, large Diameter, and Evolution over time.

Physical Examination

Skin

  • Although melanoma can occur anywhere, melanoma among women occurs more commonly on the extremities, and among men it occurs more commonly on the trunk or head and neck.
  • Patients with suspected melanoma should have a full-body examination for other lesions.
  • A - Asymmetry (suggestive of melanoma)[1][2]
  • B - Border irregularity (suggestive of melanoma)
  • C - Color (irregular color or discoloration, very dark color suggestive of melanoma)
  • D - Diameter (large size or increase in size suggestive of melanoma)
  • E - Evolution over time
  • Other signs in a nevus that would suggest a malignant change include the following:
