Initial ovarian teratoma with immature elements. (a) Sections of immature teratoma revealed a neoplasm composed of heterogenous elements that included a dermoid cyst, fibroadipose tissue, cartilage, pigmented choroid, and glial tissue (H&E ×100). (b) Cystically dilated glands with enteric differentiation were present (H&E ×100), (c) as well as several foci of immature neuroepithelium (H&E ×200).
