47例骨髓穿刺干抽的临床和病理分析

分析４７例骨髓穿刺干抽的临床和病理改变，干抽占同期１３１９例骨穿的３．６％。根据骨髓细胞的密度和间质纤维增殖的程度，把干抽的原因分为４类：高细胞伴间质细胞增多者１９例（４２．２％）；间质细胞增多者１４例（３１．１％）；高细胞者８例（１７．８％）及低细胞者４例（８．９％）。主要疾病为：急性淋巴细胞白血病（２５．５％），急性非淋巴细胞白血病（１７．０％），慢性白血病（１４．９％），骨髓转移瘤（１０．６

Clinicopathologic Analyses of 47 Cases of Dry Tap Bone Marrow Aspirations

47 cases of clinicopathologic changes in dry tap bone marrow aspirations were analysed. Among 1319 simultaneous bone marrow aspirations, 47 were "dry tap" (3. 6%). According to the density of cells and degree of hy-perplasia of interstital fibers, the causes of "dry tap " were divided into four categories, high cell density with hyperplasia of interstitial cells 19 cases (42. 2%); hyperplasia of interstitial cells 14 cases (31.1%); high cell density 8 cases (17.8%); and low cell density 4 cases (8.9%). The frequent diagnoses were acute lymphogenous leukemia (25.5%), acute non-lymphogenous leukemia (17.0%),. chronicleukemia (14.9%), metastatic carcinoma (10. 6%), aplastic anemia (6. 4%) and primary myelofibrosis (6. 4%). Of the 47 cases of "dry tap", 27 were leukemia (57.4%). The cause of "dry tap "in leukemia had relation to hyperplasia of interstitial cells and/or high cell density; the cause of "dry tap" in metastatic carcinoma had relation to secondary myelofibrosis ; and the cause of "dry tap" in aplastic anemia had relation to marked decrease of marrow cells.
