case_images: Photomicrograph composite - Carcinoma composed of hyperchromatic, blue cells with angulated nuclei, having marked crushing. The cells do not have appreciable cytoplasm and are packed closely, demonstrating faceting. Confluent necrosis is evident. (1: H and E, x10; 2: H and E, x20; 3: H and E, x40). Immunohistochemistry- (4: NSE, x40), (5: Synaptophysin, x40); (6: Ki67, x40)
