ABSTRACT

Melanocytoma is a benign lesion caused by proliferation of the melanocytes normally found in the uvea. They can occur anywhere along the uveal tract, although the optic disc is the most common site. It is typically of adult hyper pigmented individuals, unilateral, asymptomatic, stationary and rarely undergoes a malignant transformation. Melanocytomas are uniformly densely hyperpigmented isolated lesions found on the optic nerve, choroid, ciliary body and iris that may present with pigment dispersion and secondary elevated IOP and should not be necessarily be interpreted as a sign of malignant transformation. They have a strong tendency to undergo necrosis and fragmentation leading to pigment release (after surgical procedures or injuries) and may simulates melanoma with hyphema, ectopia or secondary glaucoma.
We report clinico-echographic and pathologic features of a case of iris melanocytoma which simulated melanoma and developed secondary glaucoma.
