Purpose:
To report a melanocytoma of the optic disk in an adult who had prior photographic documentation that the affected disk was entirely normal.
Methods:
Clinical evaluation and fundus photography.
Results:
An asymptomatic 45-year-old woman was found on routine ocular examination to have a typical melanocytoma in her right optic disk. Fundus photographs made 13 years earlier showed a normal right optic disk with no sign of melanocytoma or other pigmented lesion.
Conclusions:
Although optic disk melanocytoma is generally believed to be a congenital lesion, it can apparently develop spontaneously in adulthood.
