A 15-year-old girl was born with a unilateral pigmented lesion of the conjunctiva. The patient has been observed for 11 years, showing very slow but steady progression of the pigmentation. The tumor mass was biopsied and studied with light and electron microscopy. The pigmented portion of the lesion was composed of densely packed normal-appearing subepithelial melanocytes and a nonpigmented nodule consisting of ectopic lacrimal gland tissue.
