- Myelodysplastic disorders, myeloproliferative neoplasms.

What is bone marrow trephine biopsy?
Bone marrow aspiration and trephine biopsy A trephine biopsy, sometimes done with a second needle, removes a small piece of bone with the marrow inside. The bone marrow samples are sent to a laboratory for examination under a microscope.
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.
What is the difference between bone marrow and biopsy?
Bone marrow aspiration is a procedure that takes out a small amount of bone marrow fluid through a needle. Bone marrow biopsy uses a needle to take out a small amount of bone with the marrow inside it. These samples are then checked under a microscope.
What are the indications for bone marrow aspiration and biopsy?
Indications have included diagnosis, staging, and therapeutic monitoring for lymphoproliferative disorders such as chronic lymphocytic leukemia CLL), Hodgkin and non-Hodgkin lymphoma, hairy cell leukemia, myeloproliferative disorders, myelodysplastic syndrome and multiple myeloma.
Why would you need a bone marrow biopsy?
If you have a certain type of cancer like lymphoma, a bone marrow biopsy is done to help stage the cancer by determining whether or not the cancer is in the bone marrow. Abnormal results may be due to cancer, infection, or another bone marrow disease. Your doctor may need to order more tests to confirm a diagnosis.
What is a trephine biopsy used for?
A trephine biopsy is always indicated if bone marrow examination is being performed for suspected granulomatous diseases such as sarcoidosis, tuberculosis, cryptococcosis, or histoplasmosis.
Why the bone marrow biopsy is important for the diagnosis of an aplastic anemia case?
Bone marrow biopsy. The sample is examined under a microscope to rule out other blood-related diseases. In aplastic anemia, bone marrow contains fewer blood cells than normal. Confirming a diagnosis of aplastic anemia requires a bone marrow biopsy.
What is involved in bone marrow biopsy?
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 Using a syringe attached to the needle, a sample of the liquid portion of the bone marrow is withdrawn. You may feel a brief sharp pain or stinging. The aspiration takes only a few minutes.
What does a biopsy determine?
Biopsy analysis and results The results help your doctor determine whether the cells are cancerous. If the cells are cancerous, the biopsy results can tell your doctor where the cancer originated — the type of cancer. A biopsy also helps your doctor determine how aggressive your cancer is — the cancer’s grade.
What is the purpose of a bone marrow biopsy?
Bone marrow aspiration and bone marrow biopsy can show whether your bone marrow is healthy and making normal amounts of blood cells. Doctors use these procedures to diagnose and monitor blood and marrow diseases, including some cancers, as well as fevers of unknown origin.
When to perform a trephine bone marrow aspiration?
Trephine biopsies of the bone marrow should be carried out, when clinically indicated, by trained individuals following a standard operating procedure. A bone marrow aspiration should be performed as part of the same procedure. For patient safety and convenience, biopsies are usually performed on the posterior iliac crest.
Can a trephine biopsy be used to detect lymphoid?
In such patients, an aspirate will probably be inadequate or even impossible. Similarly, only a trephine biopsy shows the architecture of the bone marrow and permits the detection of an abnormal distribution of cells, bone marrow granulomas, and focal lymphoid infiltrates.
What do you need to know about a bone marrow biopsy?
A bone marrow (trephine) biopsy is when a small core of the bone marrow tissue is removed in one piece. The sample of tissue will be examined under a microscope to look for abnormal cells. Preparation Before Your Procedure You may need a blood test shortly before the bone marrow procedure to check how well your blood will clot.
What are the common clinical indications for bone marrow aspiration?
COMMON CLINICAL INDICATIONS FOR BONE MARROW TREPHINE BIOPSY Inadequate or failed marrow aspiration; Suspected bone marrow fibrosis; Investigation and staging of Hodgkin’s and non-Hodgkin’s lymphoma, and small blue round cell tumours of childhood (neuroblastoma, rhabdomyosarcoma and Ewing’s sarcoma); and
