Benign mole:
- Small (less than 6 mm) macule or papule
- Well-defined border
- Homogeneous beige or pink to dark brown pigment
- Represent benign melanocytic growths
Junctional nevi:
- Early in life
- Often appear as flat
- Small, brown lesions
- Nevus cells are at the junction of the epidermis and dermis
Compound nevi:
- Overtime
- They enlarge and often become raised
- Reflect the appearance of a dermal component
Progression
- May darken and grow during pregnancy.
- Most moles have lost their junctional component and dark pigmentation as the white patients enter their eighth decade
Screening
- Normal moles: well-demarcated, symmetric, and uniform in contour and color at every stage of life,
- Regular mole screening: not an evidence-based recommendation for all adults
