Figure 4. Different tissue specimens under the microscope. Sections showed a mixture of embryonal and adult tissues derived from all 3 germ layers in solid and cystic fashion. Immature primitive neuroepithelial elements were seen in multiple foci. Figure A–E represent different parts of the teratoma tissue under microscope with 40-power magnification and hematoxylin and eosin staining) In Figure A, red arrow shows neural tissue in a glial texture shown with blue. In Figure B, skin tissue is shown with pilosebaceous elements shown with red arrow. Figure C shows immature neural tissue and cellular foci with small round to oval cells presenting immature cells in loose stroma shown with blue arrow. Figure D shows glial tissue with red arrow. Figure E presents immature epithelial tissue resembling both skin and lung epithelial tissue, shown with blue arrow.
