Which of the following is the most likely to turn malignant?
1) Intradermal nevus
2) Junctional nevus
3) Lichen planus
4) Papilloma

📝 Explanation:

Junctional nevi are moles where the nevus cells (melanocytes) are located at the junction of the epidermis (outer layer of skin) and the dermis (inner layer of skin). Because they are in the basal layer of the epidermis, where melanomas originate, they have a higher potential for malignant transformation into melanoma compared to intradermal nevi, where cells are deeper in the dermis. Lichen planus and papillomas are generally benign conditions
