A malignant melanoma of the choroid was observed for three years because of an erroneous diagnosis of disciform macular degeneration. No lateral or vertical growth was noted during the observation period, but significant extrascieral extension was discovered at the time of radioactive phosphorus uptake test and enucleation.
