Ovarian growing teratoma syndrome with multiple metastases in the abdominal cavity and liver: A case report

Figure 2 Postoperative histopathology combined with immunohistochemistry analysis demonstrated purely mature teratomatous tissues. A: Shows that the pathological immunohistochemical results are positive for cytokeratin; B: Shows that the pathological immunohistochemical results are negative for cytokeratin 7; C: Shows that the pathological immunohistochemical results are is HE staining; D: Shows that the pathological immunohistochemical results are positive for cluster of differentiation 56. The pathological results were obtained under a microscope with a magnification of 40 times, in which figure A is cytokeratin (+), figure B is cytokeratin 7 (-), figure C is HE staining, figure D is cluster of differentiation 56 (+), and orange arrows mark a large number of nerves endocrine cell aggregation, and all pathological results showed no immature neural tube, suggesting a mature teratoma.
