Figure 7: Photomicrograph (H and E, ×200) showing a melanoma disposed in sheets showing focal melanin pigment and round to ovoid pleomorphic tumor cells, numerous mitotic figures, and a large, nucleoli (a). On bleaching, melanin pigment got bleached (b). Tumor cells are positive for S-100 (c: ×200) and HMB-45 (d: ×200)
