Atypical Nevi

Moles known as atypical  nevi or atypical moles are larger than average (usually larger than a pencil eraser) and irregular in shape. They tend to have uneven color with dark brown centers and lighter, sometimes reddish, uneven border or black dots at edge. These moles often run in families.

People with atypical nevi may have a greater chance of developing malignant melanoma and should be seen regularly by a dermatologist to check for any changes that might indicate skin cancer. They should also learn to do regular self-examinations, looking for changes in the color, size or shape of their moles or the appearance of new moles. Sunscreen and protective clothing should be used to shield moles from sun exposure.

Recognizing the early warning signs of malignant melanoma is important. Remember the ABCDEs of melanoma when examining your moles.

A stands for ASYMMETRY; one half unlike the other half.	B stands for BORDER; irregular, scalloped or poorly defined border.
C stands for COLOR; varied from one area to another; shades of tan and brown, black; sometimes white, red or blue.	D stands for DIAMETER; while melanomas are usually greater than 6mm (the size of a pencil eraser) when diagnosed, they can be smaller.
