The osteo-sarcoma is characterised by the formation in the tumour of bone, the medullary spaces being occupied by sarcomatous cells in place of marrow. The osteoid sarcoma is characterised by the formation of a tissue resembling bone but deficient in lime salts, and the petrifying sarcoma by the formation of calcified areas in the stroma.
It may affect any bone, but rarely involves an articulation; at times it skips the joint and goes to the neighboring bone. A case of nasal sarcoma is shown by Moore. The tumor was located in the nasal septum, and caused a frightful deformity. In this case pain was absent, the sense of smell was lost, and the sight of the right eye impaired.
The differential diagnosis is to be made from abscess, bursal cyst, enlarged glands, and sarcoma, especially pulsating sarcoma of one of the bones entering into the knee joint. The choice of operation lies between ligation of the femoral artery in Hunter's canal, and Matas' operation of aneurysmo-arteriorrhaphy.
The chordoma is a rare form of tumour originating from the remains of the notochord in the region of the spheno-occipital synchondrosis or in the sacro-coccygeal region. Diagnosis of Sarcoma. A sarcoma is to be differentiated from an inflammatory swelling such as results from tubercle, actinomycosis, or syphilis, from an innocent tumour, and from a cancer.
Myeloma occurs in the jaws, taking origin in the marrow or from the periosteum of the alveolar process, and is described elsewhere. #Sarcoma# and #endothelioma# are the commonest tumours of bone, and present wide variations in structure and in clinical features.
The conditions most liable to be mistaken for syphilitic disease of bone are chronic staphylococcal osteomyelitis, tuberculosis, and sarcoma; and the diagnosis is to be made by the history and progress of the disease, the result of examination with the X-rays, and the results of specific tests and treatment. Treatment.
Rupture may take place externally, or into the cellular tissue of the iliac fossa. These aneurysms have to be diagnosed from pulsating sarcoma growing from the pelvic bones, and from an abscess or a mass of enlarged lymph glands overlying the artery and transmitting its pulsation.
Thus, in virtue of the size and character of the cells, we have the small round-celled and the large round-celled sarcoma, the small and the large spindle-celled, the giant-celled and the mixed-celled sarcoma. The lympho-sarcoma presents a structure similar to that of lymph-follicular tissue, and the alveolar sarcoma an arrangement of cells in alveoli resembling that seen in cancers.
Osteomalacia associated with New Growths in the Skeleton. When secondary cancer is widely distributed throughout the skeleton, it is associated with softening of the bones, as a result of which they readily bend or break, and after death are easily cut with a knife. In the disease known as multiple myeloma, the interior of the ribs, sternum, and bodies of the vertebræ is occupied by a reddish gelatinous pulp, the structure of which resembles sarcoma; the bones are reduced to a mere shell, and may break on the slightest pressure; the urine contains albumose, a substance resembling albumen but coagulating at a comparatively low temperature (140°
The extension of malignant disease, whether cancer or sarcoma, can often be traced along these deeper lymphatics into the pelvis, and as the obstruction to the flow of lymph increases there is a corresponding increase in the swollen dropsical condition of the lower limb on the same side. The glands of the thorax and abdomen will be considered with the surgery of these regions.
