This is a pea like tumor growing from the tarsal cartilage, its
flattened side toward the mucosa, which is red and angry, and its round
surface toward the skin. When manipulated between the fingers it moves
with the tarsus. It is usually of slow growth and may continue for years
apparently unchanged. Some have thought it tuberculous, but its true
nature is uncertain. Warner records the disease in the horse.
_Treatment_ consists in incision and removal of the tumor, curretting of
the cavity, and after antiseptic douching, suturing the lips.
