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.

On physical examination, the ABCDE for distinguishing benign nevi from malignant melanoma are:

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:

Development of satellites
Ulceration or bleeding (late signs)^[3]^[4]^[5]

Any suggestive findings detected on physical exam warrant a complete excisional biopsy. To view the complete approach for a suspected melanoma, click here.
