title: Uterine teratoma with lymphoid hyperplasia.
abstract: A mature teratoma of the uterine cervix, which was found nine months after delivery, was presented. This case was the ninth in the world, the first in Japan. Differential diagnosis and histogenesis of the uterine teratoma were discussed on the basis of histologic findings of this tumor and a review of literatures. Among the microscopic findings obtained, the conspicuous lymphoid tissue in the tumor was worthy of note, because it could be speculated to be an immunological reaction to the cells composing the tumor. It was also suggested from the post-partum occurrence that a fetal-cell origin would be possible in the histogenesis, although further positive studies on this opinion should be necessary in coming cases.
