[描述] 片号:3178。胃幽门窦部粘膜,表面为再生和增生的上皮细胞,许多腺管也是新生的,腺管间距增宽,因而形成一些宽舌样结构。从再生脉管的腺颈部水平发生了癌变。癌细胞立方形,核增大,浓染,形成不规则的腺管状癌巢(照片中的暗色腺管)。粘膜深层仍残存一些分化良好的幽门腺。 [Description] Part number: 3178. Gastric pyloric sinus mucosa, the surface of the regeneration and proliferation of epithelial cells, many of the glands are also new, widened glandular spacing, and thus the formation of some wide tongue-like structure. Carcinogenesis has occurred at the level of the neck of the regenerating vasculature. The cancer cells are cubic in shape, with enlarged nuclei, densely stained, and irregularly formed nestles of tubular ducts (dark glands in the picture). Some well-differentiated pyloric glands remain in the deeper mucosa.
