Vascular tumours, such as sarcoma and goitre, may yield an expansile pulsation and a soft, whifling bruit, but they differ from an aneurysm in that they are not diminished in size by compression of the main artery, nor can they be emptied by pressure. The exaggerated pulsation sometimes observed in the abdominal aorta, the "pulsating aorta" seen in women, should not be mistaken for aneurysm.
The man with the grey beard murmured: "I detected sarcoma." He put his finger on his neck. "Right here." The other man nodded his head seemed to be nodding continually and muttered: "Yes. There's no possibility of operating." "Of course not," said the old specialist, his eyes shining with a kind of sinister irony. "There's only one thing that could remove it the guillotine.
When it affects the lower jaw, in its early stages, actinomycosis may closely simulate a periosteal sarcoma. [Illustration: FIG.
#Secondary Cancer of the Skin.# Cancer may spread to the skin from a subjacent growth by direct continuity or by way of the lymphatics. Both of these processes are so well illustrated in cases of mammary cancer that they will be described in relation to that disease. #Sarcoma# of various types is met with in the skin. The fibroma, after excision, may recur as a fibro-sarcoma.
The conditions most likely to be mistaken for it are a soft, rapidly growing sarcoma, and a normal artery raised on a cervical rib. On account of the relations of the artery and of its branches, treatment is attended with greater difficulty and danger in subclavian than in almost any other form of external aneurysm.
In cancers under the skin, the Röntgen rays are less efficient; if radium is employed, the tube containing it should be inserted into the substance of the tumour after the method described in connection with sarcoma and another tube should be placed on the overlying skin.
The sarcoma tends to spread along the lymph spaces in the long axis of the nerve, as well as to implicate the surrounding tissues, and it is liable to give rise to secondary growths. The malignant neuroma is met with chiefly in the sciatic and other large nerves of the limbs.
The myeloma is also to be diagnosed from chondroma, from sarcoma, and from osteomyelitis fibrosa cystica. [Illustration: FIG.
Once I thought he had no suspicion at all. Then he seemed to understand his case as well as I did." "Sarcoma forms like the human embryo," said the younger doctor. "Yes, like the human embryo," the other assented and entered into a long elaboration of this idea. "The germ acts on the cell, as Lancereaux has pointed out, in the same way as a spermatozoon.
The pain varies in intensity, and may be continuous or intermittent, and there is tenderness on pressure. The shaft is increased in girth as a result of its being surrounded by a new case of bone. The resemblance to sarcoma may be very close, but the swelling is not as defined as in sarcoma, nor does it ever assume the characteristic "leg of mutton" shape.
