Combination topical therapy for conjunctival primary acquired melanosis with atypia and periocular lentigo maligna.

PURPOSE: To report the case of a patient who initially presented with primary acquired melanosis (PAM) without atypia of the conjunctiva and later developed lentigo maligna of the eyelids and PAM with atypia of the conjunctiva. We illustrate the utility of combination topical therapy with adjunctive cryotherapy to treat extensive eyelid and conjunctival lesions.

METHODS

Case report with a review of the current literature.

RESULTS

Combination of imiquimod 5% cream (Aldara, 3M Pharmaceuticals) and cryotherapy for periorbital lentigo maligna with topical interferon-α2b for conjunctival PAM with atypia led to clinical resolution of pigmented lesions for 21 months.

CONCLUSIONS

In our experience, combination topical therapy provides an effective alternative to surgery with superior cosmetic and functional outcomes.
