title: Conjunctival and corneal intraepithelial and invasive neoplasia.
abstract: The histopathologic findings and clinical records of 98 patients with conjunctival and corneal intraepithelial neoplasia (CIN) and 22 patients with invasive neoplasia were studied. Pathologic material was evaluated for cell type, degree of dysplasia, margins of excision, and change in pattern with recurrence. Clinical records were reviewed for demographic features, presenting symptoms, clinical appearance, therapy, and subsequent course. Recurrences occurred in 23 patients with CIN and 9 patients with invasive neoplasia. Intraocular or orbital extensions or both occurred in four patients and metastatic disease in two patients. The cell type, clinical appearance, and degree of dysplasia did not correlate with recurrence; involvement of the margins of the initial excision was an important prognostic sign for recurrence.
