To study the clinical and histopathologic features of cutaneous eyelid melanomas and identify prognostic factors in the behavior of such tumors. ⋯ Eyelid skin melanomas have a relatively good clinical prognosis. The histologic type and thickness of the primary melanoma were not clearly related to the clinical behavior once they were completely excised. The use of very narrow excisions of 5 mm or less was associated with greater frequency of local recurrence. Lentigo maligna melanomas were the largest tumors at presentation and, despite being thinner, were a greater surgical challenge. This type of melanoma is almost certainly underdiagnosed by ophthalmologists.
