| Malignant
melanomas of the lid, although uncommon, may occur spontaneously or
secondary to malignant transformation of a pre-existing nevus. Histopathologically (#21871), the tumor cell type is similar
to that seen in malignant melanoma of the skin rather than that of the
globe. The cells may show a
spindle-type configuration or an epithelioid- type of configuration with
marked cellular dysplasia and invasion into the dermis of the lid
(#21873).
