(a) Tumor cells arranged in solid sheets (H and E, ×100); (b) tumor cells displaying ill-defined fascicles of spindle-shaped cells and containing melanin in cell cytoplasm (H and E, ×200); (c) epithelioid morphology of tumor cells (H and E, ×200); (d) pleomorphic tumor cells with prominent central nucleoli and mitotic activity admixed with melanophages (H and E, ×400)
