A certain connection between cancerons degeneration and round-celledfibro-sarcomata cannot, after what has been stated, bo positively connection is, however, so mucli more marked and constant in casesof so-called diffuse sarcomata, that it is almost doubtful whether tlieyshould be considered as a special variety of neoplasmata. The term diffusesarcoma, sarcoma of the uterine mucous membrane, has been used sinceVirchows time to designate a new growth proceeding from the connec-tive tissue of the uterine mucous membrane, consisting mostly of small,closely-packed, round cells, though sometimes of spindle-cells, and con-. FiG. 30.—Sarcoma op the Uterus. (Gusserow^s Case.) stituting an exceedingly soft, friable infiltration of the mucous occurs in isolated clumps, or it may lead to a more decidedly sym-metrical proliferation of the entire mucous membrane. It usually in-volves the uterine muscles, infiltrates or penetrates the walls of the uterus,and even leads to the development of the peculiar new growths upon theexternal uterine surface. (Conf. the cases of West and two of the authors,one of which is published and is represented by Fig. No. 30.) The infiltration finally extends to the abdominal viscera and the ab-dominal walls, involving the adjacent organs in the sarcomatous degenera-tion. Yirchow first called attention to the primary development of the very SARCOMA. 829 soft, ronnd-cell, medullary sarcoma of the uterine mucous membrane,but characterized it as very rare. Cases of this kind have, however, been rapidly multiplied recently, and
