Teratomas, while no longer looked on as a judgment from God, continue to intrigue and mystify the student of oncology. As a group, teratomas are among the rare forms of growth. In previous communications by Hundling,1 Moersch2 and Whittaker and Pemberton,3 the rarity of sacral growths has been emphasized. These authors reported a total of 14 dermoids and 1 teratoma of the sacrococcygeal region. Whittaker and Pemberton concluded that ventral tumors of the sacrum occurred about once among 40,000 registrations at the Mayo Clinic and that only a small percentage of such tumors belonged to the group of congenital abnormalities. The rarity of teratoma of the sacrococcygeal region of adults, therefore, justifies this report. According to Harrington,4 the sites of occurrence of teratoma, in order of frequency, are the pelvis, the abdomen, the sacrococcygeal region and the thorax. To these should be added the nervous system.
