Purpose: To report findings of unusual multifocal pigmented lesions in a single patient with sector uveal melanocytosis.
Methods: Retrospective case report of an otherwise healthy 64-year-old man with unusual uveal pigmentation. Complete ocular examination, including slit-lamp biomicroscopy, ophthalmoscopy, optical coherence tomography, and ultrasound biomicroscopy, was performed.
Results: Slit-lamp examination disclosed inferior sector pigmentation of the iris. Ophthalmoscopy showed multiple discrete, deeply pigmented, inferior choroidal lesions, and ultrasound biomicroscopy confirmed a small inferior ciliary body mass. The findings were consistent with sector uveal melanocytosis, believed to be the same as a diffuse melanocytoma.
Conclusion: Melanocytoma is typically a unilateral, unifocal lesion that occurs on the optic disc but can be located anywhere in the uveal tract. This is a case of unusual pigmented uveal lesions, likely representing a variant of sector uveal melanocytosis or multiple diffuse uveal melanocytomas.
