What is Nevus (Mole) Evaluation?

A nevus (mole) is a benign pigmented lesion formed by the clustering of melanocytes. It may be present at birth (congenital nevus) or appear later (acquired nevus). It is common for a normal adult to have 10-40 moles.

Most moles are benign, but atypical (dysplastic) nevi can constitute a risk factor for melanoma development. The ABCDE rule (Asymmetry, Border, Color, Diameter, Evolution) is used in evaluation.

Examination with a dermatoscope is very important for early melanoma diagnosis. Individuals in the high-risk group (family history, multiple nevi, atypical nevi) should undergo an annual total body examination.

Symptoms

Well-defined, single-colored brown lesions (benign nevus)
Dome-shaped or flat lesions
Hair may be present on them
Slow growth and color change over time
Increase in number during puberty and pregnancy
Asymmetry and color heterogeneity in atypical nevi
Rapid change, itching, bleeding in melanoma suspicion

Risk Factors

Fair skin and red hair
Family history (melanoma, atypical nevus syndrome)
History of sunburn in childhood
Many moles (>50)
Presence of atypical/dysplastic nevi
Immunosuppression
Tanning bed use

When to See a Doctor?

If you experience any of the following symptoms, seek medical attention promptly:

  • Change in size, shape, or color of the mole
  • Asymmetrical or irregularly bordered lesion
  • Diameter greater than 6 mm or diameter increase
  • Bleeding, itching, pain, or ulceration
  • New pigment band appearing under the nail
