TUMORS OF THE EYELIDS.
Warts. The most common tumors of the eyelids in horses, cattle, and dogs are warts. These are most simply disposed of by seizing them with rat-tooth forceps and clipping them off with sharp scissors curved on the flat. Any bleeding may be checked by a pencil of silver nitrate.
Sarcoma, melanoma, and epithelioma are common in solipeds, especially in the gray and white. They usually form a cauliflower-like mass red and angry and bleed easily. They may occupy any part of the lid, the skin, the dark tarsal margin, the connective tissue or the mucosa, and not unfrequently they involve the eyeball, and the surrounding tissues, even the bones of the orbit.
Treatment. These may be excised like warts taking care to remove every vestige of disease. In these cases I have usually found it necessary to remove the entire bulb.
