Conjunctival and uveal melanoma in the dysplastic nevus syndrome.

Author information

Department of Pathology, Vancouver General Hospital, BC, Canada.


The dysplastic nevus syndrome was conceptualized in the late 1970s, and the subsequent proposal of a genetic relationship with ocular melanoma has stimulated debate in the literature which remains unresolved. We present the case of a 60-year-old man with histologically proven sporadic dysplasic nevus syndrome and a prior history of nine cutaneous melanomas, who developed a large, exophytic melanoma of the cornea and limbal conjunctiva. Cytogenetic analysis of this melanoma revealed a clonal 1;14 translocation. We believe this is the first reported case to use cytogenetic techniques in the analysis of conjunctival melanoma, either associated with dysplastic nevus syndrome or in isolation. We review the clinical literature as well as the cytogenetic and molecular genetic data related to the possible association of cutaneous melanoma, conjunctival and uveal melanoma and the dysplastic nevus syndrome.
