CANCER OF THE PROSTATE.
Lafosse records as colloid cancer a case of diseased prostate in an ox, in which the mass approximated to the size of the human head, and was made up of numerous cavities the largest not over 1½ inch in diameter, and all intercommunicating, and containing a gluey, or gelatinoid liquid with numerous small round cells and a few multinucleated giant cells. No evidence is given of the implication of even the adjoining lymph glands, so that the case was probably only an enlarged cystic prostate.
Fournier records a case in a three year old horse, which on necropsy showed a ruptured bladder, general peritonitis, and an enlarged prostate, involving Cowper’s glands. Nocard identified its cancerous nature by microscopic examination. Yet there is not a word of the implication of adjacent lymph glands.
Goubaux says prostatic cancer is common in dogs.
