Dysplastic nevi are a precursor to melanoma. They have irregular, "dysplastic" borders. Remember the "B" in ABCD stands for irregular Borders. Nevus means mole.
Other answers:
acanthosis nigricans - Darkening of skin associated with Type II diabetes mellitus
basal cell carcinoma of skin - Rarely, if ever metastasizes. Commonly affects upper lip.
blue nevus - Blue-colored type of common mole. Benign.
pg32Can anyone explain how we can rule out C or E purely based on the question stem? If we read into the question that we are looking for something related to melanoma, then I get why we can rule out C and E. However, the question simply asks which lesion appears on both sun-exposed and nonsun-exposed areas of the patient's skin. I would say that C, D and E can all occur in that distribution pattern. +7
paperbackwriter@pg32 because it specifies "this patient's skin," and the only ones he is more likely to get than the average person because of his family history are dysplastic nevi +2
