急性单核细胞白血病细胞超微结构特征:(1)原始单核细胞:胞体大,外形不整齐,胞浆丰富,胞膜边缘见少数小泡。核大呈椭圆形,异染色质极少。有1~2个核仁。(2)幼稚单核细胞:胞体更大,外形更不整齐,胞浆更丰富,电子致密颗粒易见。胞质内吞饮小泡很多。核有凹陷或切迹。(3)单核细胞:胞质丰富,细胞器发育好,核呈肾形或分叶。特异性皮损超微结构:(1)白血病性单核细胞有吞噬现象,可吞噬红细胞或细胞碎片,胞浆丰富,有长伪
Acute monocytic leukemia cells ultrastructural features: (1) the original mononuclear cells: big body cell body, irregular shape, rich in cytoplasm, cell membrane edge see a few vesicles. Large oval nuclei, very few heterochromatin. There are 1 to 2 nucleoli. (2) naive monocytes: greater body cell body, shape is more irregular, more abundant cytoplasm, electron dense particles easily seen. Cytoplasmic endocytosis drink a lot of vesicles. The nucleus is hollow or notch. (3) monocytes: rich in cytoplasm, organelles developed, the nucleus was kidney-shaped or lobulated. Specific lesions of the ultrastructure: (1) leukemia monocytes phagocytosis, phagocytosis of red blood cells or cell debris, abundant cytoplasm, pseudo-long
