骨髓转移瘤临床表现及血象无特异性,其骨髓象特征为:①骨髓易干抽,多增生不良;②瘤细胞易形成簇集现象,分布在片尾;③瘤细胞大小形态多变,染色质粗而不均匀,核仁肥大。非上皮性肿瘤与上皮性肿瘤细胞形态不同,前者虽有簇集现象,但较易散在分布,细胞大小较均一,边界清晰;后者以腺癌及未分化癌最易侵犯骨髓,二者形态亦有区别。掌握其特征可推测原发瘤的性质及部位。
The clinical manifestations of bone marrow metastases and no specific blood, the bone marrow features are as follows: ① easy bone marrow pumping, multiple hyperplasia; ② tumor cells tend to form clustering phenomenon, distributed in the tail; ③ tumor size and shape change, chromatin Coarse and uneven, hypertrophy of nucleolus. Non-epithelial tumors and epithelial tumor cells in different shapes, although the former clustering phenomenon, but more easily scattered distribution, cell size is more uniform, the boundary is clear; the latter with adenocarcinoma and undifferentiated carcinoma most likely to violate the bone marrow, the two morphology There are also differences. Grasp the characteristics of the tumor can be speculated on the nature and location of the tumor.
