ment of the skin, and the cutis isfirmly fixed, such as the ear or metatarsus, the fibroma assumes a flat,circular, coin-like appearance, and has a rough or granular surface. Insome cases there is tumefaction of the skin, as on the edge of the nose,elbow, tuberosity of the ischium, the outer part of the forearm, knee andlegs. These callosities are usually called recumbent, bed or kenneltumors. They are generally bluish-gray or grayish-red in color, rough- 480 TUMORS 481 ened externally, and irregularly circular. They vary in size from asmall pea to the palm of the hand, are generally devoid of hair, their flatsurface being smooth, furrowed, or irregularly elevated. The skinoccasionally develops acne from pressure or alteration of the tissue.Fibromata, both hard and soft, are not malignant. Many pathologists are not inclined to regard the callosities knownas bed or kennel tumors as fibromata. Most definitions of the termtumor include the clause that thev are without demonstrable cause.

This would exclude these callosities, as their cause is obvious, usuallygrowing on prominent parts, exposed to friction and pressure wheneverthe animal assumes the recumbent position. 2. The Lipoma.—These fatty tumors of the subcutis are rarer thanfibromata. They are generally round or oblong in shape, very distinctlycircumscribed, being separated from the surrounding structures by alayer of connective tissue. Sometimes they are of considerable size,but as a rule they are of very slow growth, and often pedunculated orlobular in outline and diffused in different directions. The mixed formsof lipoma and fibroma (fibrolipoma) sometimes grow to an enormous31 482 TUMORS size, and are seen as nodular collections under smooth skin. As a rulelipomata are found on the tendons and their sheaths, the chest, shoulders,and tail. Frohner found a lipoma that surrounded the anus in a half-circle. Lipomata may be multiple but are not malignant. 3. The Sarcoma.—A tumo
