Which conjunctival lesion is known for potential progression to melanoma?

Explanation:
Primary acquired melanosis is an acquired, flat pigmented lesion of the conjunctiva in adults that carries the potential to transform into melanoma, especially when there is histologic atypia. This makes PAM the lesion most associated with progression to conjunctival melanoma. Conjunctival nevus is typically benign and less likely to become melanoma; concretions and cysts are nonpigmented conditions and do not carry melanoma risk.
