Melanocytoma of the ciliary body: presentation of four cases and review of nineteen reports.

We report the clinical and histopathologic features of four cases of melanocytoma of the ciliary body, review the previously reported and presented cases, and discuss the differential diagnosis of melanocytoma of the ciliary body.
