These include: (1) tubular pattern with small, round, uniform, and back-to-back tubules, lined by cuboidal to flat cells; (2) ductal pattern typically composed of large glands with variable size, occasionally with intraglandular villous papillae and cellular budding, the glands being lined by 1 to several layers of columnar cells with endometrioid-like appearance; (3) retiform growth characterized by slitlike branching glands, some with intraglandular papillae lined by 1 to several layers of flat, cuboidal, or columnar cells; slit-like and cystic spaces may merge and impart a sievelike appearance; (4) solid pattern with nests and sheets of epithelial cells with scattered small glands; and (5) sex cordlike growth.
