aka mole | nevus |
nevus cells located within the deeper dermis | blue nevus |
where are blue nevi most commonly found | head, neck, buttocks, and dorsal hands/feet, can be seen anywhere |
perform a complete skin exam as this phenomenon may occur in vitiligo and in malignant melanoma | halo nevus |
a preexisting nevus of any type which is surrounded by a rim of depigmentation, an autoimmune phenomena preceding the disappearance of the nevus | halo nevus |
benign, pink, tan, or brown dome-shaped smooth papules, most common in children, rare in adults, most common on the face, scalp, neck, and legs | Spitz nevus |
treatement of spitz nevus | excision is recommended since melanoma has been reported to arise albeit rarely |
not a true nevus since it lacks nevus cells, it is a developmental anomaly appearing as a brown patch, a patch of hair, or both | Becker's nevus |
aka freckles | ephilides |
aka age spots, liver spots, wisdom spots | lentigo |
benign 1-2 mm well defined red, tan, or brown colored macules, increased # of melanocytes therefore they tend to darken with sun exposure and fade in the winter months | ephilides |

this BCC may resemble melanoma | pigmented BCC |
least common BCC very subtle, white to yellow patch with poorly defined borders | morpheaform BCC |
