The patient does not complain of any pain or uneasiness in the tumour, unless inflammation be excited in it; then the pain and other symptoms are such as attend incited action, and the sensations which are afterwards experienced vary according to the character which the tumour assumes. Certain changes may occur in its texture, though not in its general character or disposition; thus osseous or earthy matter is occasionally deposited in some part of the tumour, while the surrounding adipose substance retains its appearance and density. Suppuration, it is said, has followed inflammatory action, excited in an adipose sarcoma. OF FIBROUS TUMOURS. [Illustration] Fibrous tumours are not uncommon, and are formed in various textures. In general they are composed of a substance of a dirty grey colour and considerable density, through which minute, firm, ligamentous fibres ramify; in some cases irregularly, in others radiating from the centre of the tumour. The new formation is surrounded by condensed cellular tissue, to which it intimately adheres, and does not mingle irregularly with the surrounding parts; in this respect differing from malignant tumours, which occasionally contain fibrous matter. It cannot be considered of an equally innocuous nature with those already described, but is still, in its original state, not of a malignant disposition. After some time, the consistence and structure of such tumours vary: some are of a loose texture, and contain cells; others are hard, and intermixed with cartilaginous matter, or even with bone. In general, the tumour is slow in its progress, though it may attain a very large size, as seen in the cut on the preceding page, if allowed to remain; occasionally its growth is rapid.
