The round-celled sarcoma is the most generalized tumourthat affects the human body; it may occur in any tissue,osseous, muscular, nervous, thymic, ovarian, or testicular, andeven in the delicate sustentacular framework of the retina. Itattacks the body at all periods of life, from the foetus in utero 52 SARCOMAS 53 and the child just born, up to the extreme limits of age; andarises in vestigial organs, as well as in those which arein the full exercise of their functions, such as the kidneyor the parotid gland. 2. Lympho-sarcomas consist of cells identical with thoseof the round-celled species, but the cells are contained indelicate meshes: the tissue resembles that of lymph-glands(Fig. 34), hence the origin of the term lympho-sarcoma. Thesetumours must not be confounded with simple (irritative) en-largement of lymph-glands, nor with the general overgrowth oflymphadenoid tissue associated with leukaemia or lymph-.

The lympho-sarcomas exhibita very characteristic structure, occur as a rule in very definitesituations, and have somewhat special clinical features. Thesetumours occur in the superior mediastinum, in the subpleuraland subperitoneal connective tissue, at the base of the tongue,in the larynx, in the tonsil, and in the testis. Fortunately,sarcomas of this species are rare, for they are excessivelymalignant. 3. Spindle-celled sarcomas.—The cells in this speciesvary much in size, but they all agree in being oat-shaped orfusiform (Figs. 35, 36). The cells tend to run in bundles,which take different directions, so that in sections of thetumour seen under the microscope some bundles will havethe cells cut in the direction of their length, and others at 54 CONNECTIVE-TISSUE TUMOURS right angles.
