Gynecology . processes. The anatomic type of cancer of the body is invariably that of adenocarci-noma, although the process may develop into advanced stages in which theglandular arrangement is no longer apparent. The histologic picture may thenbe one of carcinoma simplex, in which the carcinomatous cells are massed to-gether with no definite arrangement. Sometimes a metaplasia takes place,like that which frequently appears in cancer of the endocervix, whereby thecells take on a squamous character, even to the formation of cornified pearls. The growth originates in the mucous membrane, and tends both to pro-liferate into the uterine cavity and to infiltrate the muscular wall of the uterus,one of these tendencies usually predominating. In the typical case that isgrowing toward the uterine cavity the microscopic appearance is that of long-branching tendrils of a papillary nature. When the disease encroaches on themuscular wall glandular offshoots are seen invading the muscle below the 304 GYNECOLOGY. Fig. 101.—Adenocarcinoma of the Body of the disease is beginning in the upper part of the canal and is extending both inward into the mus-cular wall and outward toward the canal. In this case the growth has a papillary appearance. gk V „ Tur\bv)S
