2055. Melanesia of the eyeball.
From a man, aet. thirty-six years. Duration of the dis- ease sixteen months. Pain through the organ, with redness and soreness from the first ; vision gradually affected, and none for the last six months. Swelling began six months before ; and when Dr. B. saw him there was a disorganized mass, of the size of a small apple, red, firm, and covered at the lower part by the everted conjunctiva.
After removal the mass had an ovoid form, was some- what knobbed upon the surface, and measured upon incis- ion, antero-posteriorly, a trifle over l in., and transversely l in. The outline of the globe upon this surface was distinct throughout, had somewhat the form of a chestnut, and was completely filled by a uniform, black mass, but not enlarged. Upon one side the sclerotic appeared quite healthy. A trace of the cornea was seen, but not of the lens nor anterior chamber. Just outside of the globe was a large and similar black mass. The remain- der, which constituted a majority of the whole, varied much in color, and consisted partly of a uniform, close, compact white structure, without any trace of discolora- tion, though by far the greater part was more or less dis- colored, and passed almost gradually into the black por- tion. These differently colored portions were distinct, and seemed almost composed of separate lobules. From the posterior extremity of the mass to the globe of the eye the distance was 1J in. } the optic nerve being nowhere distinctly seen.
Dr. B. remarked that this was the fifth case of cancer of the eye that he had operated upon ; and of these, three were of the melanotic form. Also, that the subject of the above case was the youngest of all of the patients. (Am. Jour, of Med. Sc. Vol. xxi. p. 41.) 1852.

2056. Globe, not enlarged, but filled with a black melanotic mass ; with a mass of the same external to it, and nearly an inch in diameter. Sclerotic quite distinct, on section ; and there is a small, and very hard, cretaceous body in place of the lens. 1861. Dr. C. Ellis.
