Purpose:
It is essential to assess the yield of routine histopathological examination of pterygium specimens excised from clinically benign pterygium. The purpose of this study was to determine the rate of histopathologically identified ocular surface squamous neoplasia (OSSN) in clinically benign pterygium specimens.
Materials And Methods:
This retrospective consecutive study consisted of patients from the cornea services of the ophthalmology departments of Meir Medical Center, Kfar Sava, and Rabin Medical Center, Petah Tikva, Israel. Included patients were those with clinically benign pterygium who underwent pterygium excision between January 2002 and December 2011. The pterygium specimens were sent for histopathological examination and the pathology reports were reviewed for evidence of OSSN.
Results:
Overall, pathology reports of 682 eyes of 585 sequential patients were included in the study. There was a male predominance of cases (59%). Patients' age ranged from 16 to 87 years with an average age of 56 years. Six hundred and forty-three cases were primary (94%) and 39 cases were recurrent (6%).
Conclusions:
Cases of clinically benign pterygium diagnosed and excised by an experienced corneal expert are less likely to harbor OSSN. The yield of routine histopathological examination of such specimens may be low.
