An implanted fetus in the sacralregion, only one of the lower limbsand the imperforate ano-genital orifice remaining, is shown in Figure 439. The included parasitic fetus is often blighted at a veiy early stage,and none of its organs reach a full degree of development. The moreimportant organs either are absent or are present only in a rudimentaryform. This form of teratoma has been well described by Sutton as acardiac Fig. 439.—Sacral teratoma with a super-numerary leg (after Sutton). 6l2 PATHOLOGY AND TREATMENT OF TUMORS. In some cases the fetus simply consists of a shapeless mass in whichonly traces of the skeleton and of the more important organs are found.
