The study was carried on the Departments of Pathology and oncology of Al-gamhouria Teaching Hospital, during the period from Jan 2005 to Dec 2005.

A total of 28 patients with suspected or confirmed malignancy underwent BMTB from the posterior superior iliac crest;.

21 patients with solid tumors and 7 patients with lymphoma.

The results show that the frequency of BM involvement by solid tumors was (47.6%) and, in 100% of patients with lymphomas,.

the breast cancer was the most common primary site of solid tumors and low grade lymphoma was the most common type of lymphoma with bone marrow involvement Conclusion: BM involvement by solid tumors, and lymphoma was common in our study.

The BMTB is an important procedure in detecting such tumors.
