Abstract
Aim: The aim of this study is to describe the clinical and pathologic features of corneal primary acquired melanosis (PAM) and melanoma. Methods: We describe 3 cases in total: two cases of corneal melanomas and 1 case of corneal PAM. The eyes were processed routinely for histopathological examination. Clinical histories, treatments, and outcomes were reviewed. Results: Corneal melanomas arose from recurrence of conjunctival melanoma or conjunctival PAM at the limbus. One patient had a recurrence after excision of a limbal melanoma, another had a de novo corneal melanoma, and the last patient had corneal PAM in the setting of conjunctival PAM with atypia. All lesions were excised with adjuvant alcohol debridement and cryotherapy with no recurrence ranging from 1 week to 8 years. Conclusions: Corneal melanomas arise at the limbus from corneal PAM or conjunctival atypia. They can appear after excisional removal of a conjunctival melanoma. Surgical excision with alcohol debridement and adjuvant cryotherapy is successful.
