What is the difference between bone marrow biopsy and trephine biopsy?
For the bone marrow aspiration, a thin needle is used to remove a sample of fluid (aspirate) from the bone marrow – usually from the pelvic bone, but sometimes from the chest. A trephine biopsy, sometimes done with a second needle, removes a small piece of bone with the marrow inside.

The needle is inserted through the bone into the bone marrow and the syringe is attached to the top to remove the sample or to deliver drugs or fluid into the bone. A Jamshidi needle is a type of bone marrow needle. Bone marrow aspiration and biopsy.
Why is fine needle aspiration done?
During a fine needle aspiration (FNA), a small amount of breast tissue or fluid is removed from a suspicious area with a thin, hollow needle and checked for cancer cells. This type of biopsy is sometimes an option if other tests show you might have breast cancer (although a core needle biopsy is often preferred).
Why trephine biopsy is used in aplastic Anemia?
A trephine biopsy of at least 2 cm is essential to assess overall cellularity and morphology of residual hemopoietic cells and to exclude abnormal infiltrates. In aplastic anemia, hypocellular marrow particles are observed.
Why trephine biopsy is done?
How is a trephine biopsy performed?
Trephine biopsy specimens, ideally of 20–40 mm, are cut into no longer than 10 mm pieces and either processed directly into the resin or decalcified, at least partly, in a mixture of 4% buffered formaldehyde and 10% disodium-EDTA dihydrate (Sigma, St Louis, Missouri, USA) at 60˚C, for 16–24 hours.
How is bone marrow aspiration performed?
The bone marrow aspiration is usually done first. The doctor or nurse makes a small incision in the skin, then inserts a hollow needle through the bone and into the bone marrow. Using a syringe attached to the needle, a sample of the liquid portion of the bone marrow is withdrawn.
What is bone marrow aspiration?
Bone marrow aspiration is a procedure that involves taking a sample of the liquid part of the soft tissue inside your bones. Bone marrow is the spongy tissue found inside bones. It contains cells that produce white blood cells (WBCs), red blood cells (RBCs), and platelets inside larger bones, such as the: breastbone.
What are the indications for bone marrow trephine biopsy?
What is trephine needle?
A trephine is a serrated blade used to remove a circle of tissue or bone used as a treatment throughout human history.

For the bone marrow aspiration, a thin needle is used to remove a sample of fluid (aspirate) from the bone marrow – usually from the pelvic bone, but sometimes from the chest. While the needle is inside the bone, small pieces of bone and marrow are also removed. This is the trephine biopsy.
What is a bone marrow aspiration?
In bone marrow aspiration, a needle is used to withdraw a sample of the fluid portion. Bone marrow biopsy and bone marrow aspiration are often done at the same time. Together, these procedures may be called a bone marrow exam.
What is included in a bone marrow morphologic study?
A thorough bone marrow morphologic study involves examination of peripheral blood smears, direct, particle, and buffy coat bone marrow smears, trephine biopsy imprints, particle and trephine biopsy sections, and marrow volumetric data. The information obtained from the study of these various specimens is complementary.
