Adenoma of the nonpigmented ciliary epithelium
1Department of Ophthalmology, Emory University School of Medicine, Atlanta, Georgia.
Background:
There is a spectrum of benign and malignant ciliary body tumors that can be classified by histopathologic examination.
Methods:
A 55-year-old woman with a history of ovarian carcinoma underwent excision of a ciliary body tumor in her right eye. The tumor was submitted for light microscopic, immuno-histochemical, and ultrastructural examination.
Results:
The tumor was composed of sheets and cords of cells with bland cytologic features. Immunohistochemical stains were positive for S-100 protein and vimentin in tumor cells. Ultrastructural examination showed intercellular junctions and thick basement membrane within the tumor.
Conclusion:
The tumor was classified as an adenoma of the ciliary body nonpigmented epithelium, a benign tumor with variable histopathologic features.
