Bone marrow biopsy

Pronunciation

Definition 1

A procedure in which a small sample of bone with bone marrow inside it is removed, usually from the hip bone. A small area of skin and the surface of the bone underneath are numbed with an anesthetic. Then, a special, wide needle is pushed into the bone and rotated to remove a sample of bone with the bone marrow inside it. The sample is sent to a laboratory to be looked at under a microscope. This procedure may be done at the same time as a bone marrow aspiration. (NCI Dictionary)

Definition 2

A biopsy involving the removal of a core tissue containing bone spicules and hematopoietic elements embedded in the marrow stroma. This procedure is done in the hip area mainly for the diagnosis and evaluation of neoplastic and non-neoplastic hematopoietic disorders (e.g. anemias, leukemias, lymphomas) and the evaluation of the spread of solid tumors (e.g. carcinomas, sarcomas) and lymphomas for therapeutic purposes.
