Maximum malignant potential is seen in: (A) Epidermal nevus, (B) Junctional nevus, (C) Dermal nevus, (D) Blue nevus
Answer is D. The diagnosis can be made by visual inspection alone. Although most cases of blue nevi are benign, there is a small possibility that a cellular blue nevus can undergo malignant transformation and become a malignant cellular blue nevus (MCBN). Thus, a biopsy of any changing or suspicious lesion should be done Ref Harrison20th edition pg 1456
