case_images: Microscopic features of arytenoid tissue samples. (a) Arytenoid mucosa showing large nests of malignant cells in the lamina propria with normal overlying surface epithelium (H&E 100x). (b) High power image showing small nests of cells plugging lymphatics in the lamina propria. Note the variability in nuclear size, irregularly shaped nuclei, and prominent nucleoli typical of ovarian serious carcinoma (H&E 400x). (c) Immunohistochemical stain for Pax8, showing nuclear positivity in the tumor cells, consistent with metastatic serous carcinoma (Pax8 400x).
