TUMORS AND HYPERTROPHY OF THE MEMBRANA NICTITANS.
Neoplasms of this organ may occur in any quadruped or bird and may be recognized by the swelling of more or less of its substance, by the unevenness of its free margin, or by distinct outgrowths from its surface. They are especially common in dogs and pigs and may be fibrous, epithelial or otherwise. The treatment is purely surgical and in case of a malignant neoplasm should demand the removal of the entire organ.
