PAM education notes regarding its nature and management include which of the following?

• A. It is benign but may progress to a malignant tumor; UV exposure association; referral to oculoplastic; annual exam next year
• B. It is an infectious bacterial lesion
• C. It always resolves without intervention
• D. It has no relation to UV exposure

Answer: (A)

Primary acquired melanosis of the conjunctiva is a pigmented lesion that is usually benign in appearance but carries a real risk of progressing to conjunctival melanoma. A key point to convey to patients is the link with UV exposure, which is why protecting the eyes from sun exposure is encouraged. Management centers on confirming the diagnosis and assessing for any epithelial or melanocytic atypia; if features are suspicious or atypia is present, the patient is referred to oculoplastic or ocular oncology for biopsy or excision with appropriate margins. Even when the lesion seems benign, regular follow-up is essential to catch any progression early, commonly through periodic examinations such as an annual check. This differs from infectious or purely self-resolving conditions and contradicts the notion that UV exposure has no relation to PAM.
