Atypical moles, or dysplastic nevi, are odd-looking moles that are unlike typical moles. Though generally benign (noncancerous), their irregular appearance may look similar to melanoma, which is a type of skin cancer. At Heights Dermatology, we stress the significance of becoming aware of these moles and checking any change in skin as soon as it occurs.
What Are Atypical Moles?
Atypical moles tend to be larger compared to normal moles and usually show uneven borders, uneven pigmentation, or a combination of tan, brown, red, and pink coloring. They are either flat or slightly elevated and may occur anywhere in the body, although mostly on the torso, scalp, or lower limbs.
Whereas regular moles keep their exact shape and color, irregular moles show asymmetry and mottled pigmentation. They are single or multiple moles and in some cases may develop over 100 in a person's lifetime.
Causes and Risk Factors
The specific reason for atypical moles is unclear, although both genetic and environmental factors come into play. Individuals who have a family history of melanoma or atypical moles are more prone to them. Repeated or extreme sun exposure, particularly in childhood, can also raise the risk.
People with fair skin, light-colored eyes, and burn susceptibility should be especially cautious. Although moles that are unusual in appearance are not cancerous by nature, when present, the risk of skin cancer, most notably melanoma, may be greater, and regular observation is therefore important.
Symptom and Warning Signs
Although the majority of unusual moles are harmless, you should keep watch for changes over a period of time. Look for the ABCDEs of mole evaluation:
- Asymmetry – one side is different from the other
- Edge - irregular, scalloped, or poorly defined borders
- Color – ranging from various shades of brown, black, to red and blue
- Diameter – greater than 6mm (approximately the size of a pencil eraser)
- Evolving – size, shape, color, or texture changes
Regular self-examination and yearly examinations by a board-certified dermatologist in Houston are essential to early detection.
