RESUMEN
The incidence of uveal melanoma, in particular that of the ciliary body, is very low in black people, including West Indians. When symptomatic, it manifests as decreased or impaired visual acuity and seldom, if ever, pain. We report a case of ciliary body melanoma that is of scientific interest for two reasons: 1) a West Indian melanoderm patient being affected, 2) presentation as a recurrent uveitis with a transient increase of intraocular pressure, and without any decline in visual acuity. We recommend that in any case of uveitis, black patients included, a ciliary body tumor should always be excluded by pupillary dilation.

CASE REPORT: We describe the unusual diagnosis of a ciliary body medulloepithelioma by histopathology of a subretinal membrane obtained from vitreoretinal surgery of a 10-year-old boy. The patient had a history of perforating trauma OS 2 years earlier, and both fundus exam and B-scan ultrasound revealed only a retinal detachment with a subretinal membrane. No detectable mass was present. DISCUSSION: The membrane removed from underneath the peripheral retina revealed a blue cell tumor confirmed by histopathology and immunohistochemistry to be a primitive neuroectodermal tumor. Currently, the patient has been followed for 5 years with no signs of recurrence.

A 57-year-old man developed a ciliary body mass, clinically diagnosed as malignant melanoma of the ciliary body, that produced a cataract in the right eye. Treatment was cataract surgery with sclerouvectomy performed simultaneously. Pathohistologic examination revealed an acquired adenoma of the nonpigmented ciliary epithelium. The clinicopathologic features and treatment of this tumor are discussed.
