Malignant Melanoma of the Lacrimal Drainage Apparatus Complicating Conjunctival Melanoma

Abstract

Melanoma of the LDA may complicate conjunctival melanoma in a significant percentage of cases having orbital exenteration. The surgical technique for orbital exenteration in patients with conjunctival melanoma should take this into account by intentionally removing the lacrimal sac and upper nasolacrimal duct as well as the lacrimal canaliculi. If melanoma is found in the LDA, consideration should be given to wider en bloc excision of the LDA.
