Malignant melanoma of the conjunctiva after 11 years.

A 76-year-old lady presented with a conjunctival malignant melanoma, which had been incompletely excised 10 years earlier. After rapid and massive growth of the tumor, which was later removed along with the globe, there was no evidence of local or systemic recurrence during 22 months of observation until the patient died of unknown causes. Pathological examination of the ocular tissues obtained at operation showed intraocular extension of tumor into Schlemm's canal and the presence of tumor cells in vascular channels in the limbal region.
