Giant adenomatoid tumors of the uterus.

Two cases of adenomatoid tumor of the uterus of unusually large size are reported. One was 12 cm, the other 13 cm in diameter and one was located in the lateral wall and the other in the posterior wall of the uterus. Both were an unusually large or giant variant of adenomatoid tumor of the uterus. The cystic macroscopical and microscopical pattern is characteristic of giant adenomatoid tumors. The origin of these neoplasms is discussed.
