Unexpected histological findings in pterygium

Optom Vis Sci. 1993 Dec;70(12):1058-60. doi: 10.1097/00006324-199312000-00012.


Pterygium is thought to be a common benign lesion of the corneo-conjunctival limbus. We report a case in which the pathological examination of an apparently trivial pterygium disclosed the presence of a conjunctival intraepithelial neoplasm in a 53-year-old white male who has been living in Kenya for 35 years. An atypical grayish area on the lesion convinced the surgeon to request the histological examination.
