目的：探讨塑料包埋骨髓活检切片对急性髓性白血病（AML）进行组织学分型的可能性。方法：对92例初诊AML患者的骨髓切片进行常染色观察。结果：5例属增生减退型，87例为增生活跃型。43例分入白血性原始细胞的纯一性浸润型，另49例为非纯一性浸润型。内59例为纤维增生型，33例分入非纤维增生型AML。结论在AML的分型中，活检切片对涂片有补充与纠正作用。
Objective: To investigate the possibility of histological typing of acute myelogenous leukemia (AML) by plastic-embedded bone marrow biopsy. Methods: Bone marrow sections of 92 newly diagnosed AML patients were observed by routine staining. RESULTS: Five cases were hyperplastic and 87 cases were hyperplasia. Forty-three patients were divided into purely infiltrating types of white blood cells and the other 49 were non-pure infiltrating types. Of the 59 cases, fibrosis was found and 33 cases were classified as non-fibrogenic type AML. Conclusion In the classification of AML, biopsy slices are complementary and corrective for smears.
