Histology of multiple pelvic lesions following repeat laparotomy demonstrated neoplasms composed of derivatives of all three germ layers, namely, ectoderm, mesoderm, and endoderm consistent with mature teratoma. (a) Mature cartilage and squamous epithelium (H&E ×100). (b) Mature neuroglia and vascular proliferation (H&E ×200). (c) Cysts lined with mature squamous and ciliated columnar respiratory epithelium and overlying mature neuroglia (H&E ×200). (d) Large cyst wall with gastric mucinous epithelium, bundles of smooth muscle, and adjacent cysts lining of the ciliated respiratory epithelium (H&E ×200).
