Nowadays , bone marrow(BM) biopsy is performed world widely, not only for correct diagnosis of hematologic disorders, but also for the evaluation of their therapeutic effects, prognosis, and detection of myelofibrosis & secondary marrow involvement .Six hundred forty-two slides of BM biopsy were reviewed. The classification of the diseases was acute leukemia(19.5%) , IDA(8.6%), aplastic anemia(6.7%), myeloproliferative disease(5.6%) etc., in order. Marked cellularity discrepancy between aspiration and biopsy was noted in 55 of 505 (10.9%).
In 75 cases of myelofibrosis (MF), CML was the most (17.3%) and MF of unknown etiology was 9 cases(12.07%. ALL showed higher frequency and more severe grading in MF than AML.
in 54 cases of solid tumor, BM metastasis was noted in 25 (46.3%) (metastatic adenocarcinoma: 57%, small cell carcinoma of the lung: 10%), and MF was combined in 6(24%) .
In 9 Cases Of NHL, 6 showed diffuse infiltration and 2 Showed nodular in biopsy. MF was combined in 3.
The 10 cases of follow up BM biopsy during therapy were reviewed, and 5 cases of AML showed decreased cellularity and increased fat cells of marrow after 1 month or more.
Five cases of CML showed decreased or increased MF and cellularity according to the disease progression.
