As the tumour increases in size, the sarcomatous tissue erupts through the capsule of the gland, and infiltrates the surrounding tissues, whereby it becomes fixed to these and to the skin. [Illustration: FIG.
Schwimmer records a curious case of universal small sarcomata over the whole body of a teacher of the age of twenty-one, in the Hungarian lowlands. The author called the disease sarcomata pigmentosum diffusum multiplex. The bones are a common seat of sarcomatous growths, the tumor in this instance being called osteosarcoma.
This peculiarity accounts for the facility with which hæmorrhage takes place into the substance of the tumour, the persistence of the bleeding when it is incised or ulcerates through the skin, and the readiness with which the sarcomatous cells are carried off and infect distant parts through the blood-stream.
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.
This gentleman's nose was divided into five lobes by sarcomatous tumors weighing two pounds, occupying the external surface of the face, adherent to the buccinator muscles to which they extended, and covering the chin. In the upright position the tumors sealed the nostrils and mouth, and the man had to bend his head before and after respiration.
There are cases on record where rapidly growing sarcomatous and angiomatous tumours, aneurysms, and the bruises that occur in hæmophylics, have been mistaken for acute abscesses and incised, with disastrous results. #Treatment of Acute Abscesses.# The dictum of John Bell, "Where there is pus, let it out," summarises the treatment of abscess.
The patient became emaciated and died thirteen days after his admission into the hospital. A histologic examination showed the sarcomatous nature of the various growths. The disease differed from "button-scurvy." Mycosis fungoides approximates, clinically and histologically, granulomata and sarcomata.
The peripheral portion consists of soft sarcomatous tissue, which invades the overlying soft parts. The articular cartilage long resists destruction. The ossifying sarcoma is met with most often in the femur and tibia, less frequently in the humerus, skull, pelvis, and jaws. In the long bones it may grow from the shaft, while the chondro-sarcoma more often originates at the extremities.
Tumours of the thyreoid, enlarged lymph glands, and fatty and sarcomatous tumours can usually be distinguished from aneurysm by the history of the swelling and by physical examination. Cystic tumours and abscesses in the neck are sometimes more difficult to differentiate on account of the apparently expansile character of the pulsation transmitted to them.
It most frequently originates from fascia, intermuscular connective tissue, periosteum, bone-marrow, and skin, and forms a rounded or nodulated tumour which appears to be encapsulated, but the capsule merely consists of the condensed surrounding tissues, and usually contains sarcomatous elements.
