Developmental Stages of Embryo-like Bodies in Teratoma Testis

Abstract

Small bodies, comparable in their morphology with that of the early developmental stages of mammalian embryos, are observed uncommonly in certain testicular teratomata (Melicow, 1940; Dixon and Moore, 1953; Evans, 1956); and although an enormous number of these embryolike structures may be scattered haphazardly throughout a teratomatous growth, it is only rarely that such bodies (Figs.
