Sarcoma of the uterus is not such a frequent condition aa was formerly supposed. Many of the cases which we now know to be adeno-carcinoma were described as sarcoma. The disease may arise in theconnective tissue of the endometrium, in which case it tends to be of adiffuse character spreading over the whole surface. It may begin as alocalised nodule in the muscular wall of the uterus, and many cases havenow been described where it takes origin in a previously existing fibro-myoma. The tumour has the naked-eye characters of sarcomata in othersituations. It is of soft consistence, of a whitish or yellowish colour onsection, and contains areas of haemorrhage and necrosis. It may attain a. Fig. 122.—Sarcoma of Utekus. Section through centre of the tumour showiug the uterine cavity and, growiug inone wall, a large tumour which projects markedly into the cavity.

The tumour is bulging into the lumen ofthe uterus, and previous to hysterectomy being performed, several largemasses were removed per vaginam. Microscopically, the characters ofthe tumour vary. It may be of the ordinary spindle-celled type, and avariety has been described where the cells are apparently directly derivedfrom the non-striped muscle cells. It is often extremely difficult to saywhether a soft fibroid is
