Choroidal melanoma with pigment dispersion in vitreous and melanomalytic glaucoma.
A 39-year-old black man underwent enucleation of the left eye because of poor vision, ocular pain, and intractable glaucoma secondary to a choroidal tumor. Two diagnostic vitrectomies, performed 11 and 7 months before enucleation, had failed to disclose the proper diagnosis. Histologic diagnosis was necrotic malignant melanoma of the choroid with melanocytoma cells, extensive pigment dispersion throughout the eye, and melanomalytic glaucoma. Possible mechanisms of tumor necrosis are reviewed.
