case_images: Microscopical aspects of melanoma. A. The tumor is composed of epithelioid cells with eosinophilic cytoplasm, polymorphic, hyperchromatic nuclei, and focally conspicuous nucleoli (HE, x50); Immunohistochemistry tests showed tumor cells positive for: B. Melan-A (anti-Melan-A Ab, x50), C. MiTF (anti-MiTF Ab, x50) and D. SOX-10 (anti-SOX-10 Ab, x100).
