Abstract

Purpose: : To determine the rate of ocular surface squamous neoplasia (OSSN) among pterygium specimens.

Methods: : Retrospective review of histopathologic slides. All histopathologic specimens from 1989-2009 with a clinical diagnosis of pterygium were reviewed. Specimens were evaluated for presence and grade of dysplasia.

Results: : A total of 288 specimens were included. The rate of any dysplasia was 2.1% (n=6). All dysplasia was low-grade. There were no cases of high-grade dysplasia or squamous cell carcinoma.

Conclusions: : The rate of dysplasia among pterygium samples in San Francisco is 2.5%. Given the rate of unsuspected dysplasia among pterygia, all pterygium specimens should be submitted for histopathologic evaluation.
