In consequence of this arrange-ment the muscular tissue with the growth of the tumor is diminished,and is replaced largely by fibrous tissue. Even if the muscular tissuealmost disappears during the growth of the tumor, its original characteras a myoma is preserved from a genetic standpoint, and this tumorshould be called a myoma, and not, as was suggested by Mijller,a desmoid, or by Rokitansky, a fibroid. As the connective tissuebecomes more abundant, the muscle-fibres arc compressed into streakswhich are sometimes difficult of recognition. The .structure of a leiomyoma is influenced by the character of themuscular in which it develops. The muscle-fibres are spindle-. ?0 ^:4m^\M- m NV^r i4H\^^a^ Fig. 336.—Myofibroma of the broad ligament; X480 (Surgical Clinic, Rush Medical College, Chicago):a, muscle-fibres in cross-section; 6, muscle-fibres inlongitudinal section ; c, interstitial elastic fibres.
