Int J Surg Pathol 2016 Sep 8;24(6):562-7. Epub 2016 May 8.

McGill University, Montreal, Quebec, Canada.

Conjunctival melanoma is the second most common conjunctival malignancy. Its differential diagnosis with other conjunctival melanocytic neoplasms is inherently difficult. The presence of epithelial cysts is a useful feature in conjunctival tumors and favors a benign lesion. Herein 2 cases of conjunctival melanoma with cysts are presented. To the best of our knowledge, this is the first series of conjunctival melanoma with epithelial inclusion cysts. This series emphasizes the importance of considering several malignant features when reviewing conjunctival melanocytic lesions, as malignancy can exist even in the presence of epithelial inclusion cysts.
