PRAME Immunohistochemistry is Useful in the Evaluation of Conjunctival Melanomas, Nevi, and Primary Acquired Melanosis.

J Cutan Pathol 2021 Jun 4. Epub 2021 Jun 4.

Department of Surgery, Section of Ophthalmology, Geisel School of Medicine, Dartmouth-Hitchcock Medical Center, Lebanon, New Hampshire.

PRAME immunohistochemistry has been widely adopted for distinguishing cutaneous nevi from melanoma, but limited data exist assessing its utility in evaluating conjunctival specimens. In particular, it is uncertain whether it can predict the risk of melanoma progression in primary acquired melanosis (PAM). Read More
