A needle no wider than that typically used to give routine injections (about 22 gauge) is inserted into a lump (tumor), and a few tens to thousands of cells are drawn up (aspirated) into a syringe. This is an extremely simple technique that has been used in Sweden for decades but has only been developed widely in the US over the last ten years. The colposcope is actually a close- focusing telescope that allows the physician to see in detail abnormal areas on the cervix of the uterus, so that a good representation of the abnormal area can be removed and sent to the pathologist.įNA biopsy. This is a gynecologic procedure that typically is used to evaluate a patient who has had an abnormal Pap smear. The endoscopist can directly visualize an abnormal area on the lining of the organ in question and pinch off tiny bits of tissue with forceps attached to a long cable that runs inside the endoscope. It is done through a fiberoptic endoscope the doctor inserts into the gastrointestinal tract (alimentary tract endoscopy), urinary bladder (cystoscopy), abdominal cavity (laparoscopy), joint cavity (arthroscopy), mid-portion of the chest (mediastinoscopy), or trachea and bronchial system (laryngoscopy and bronchoscopy), either through a natural body orifice or a small surgical incision. This is probably the most commonly performed type of biopsy. This type of biopsy is most commonly used for tumors of the soft tissues (muscle, fat, connective tissue) to distinguish benign conditions from malignant soft tissue tumors, called sarcomas. Only a portion of the lump is removed surgically. Some organs, such as the spleen, are dangerous to cut into without removing the whole organ, so excisional biopsies are preferred for these. Some surgeons prefer excisional biopsies of most breast lumps to ensure the greatest diagnostic accuracy. ![]() Some types of tumors (such as lymphoma, a cancer of the lymphocyte blood cells) have to be examined whole to allow an accurate diagnosis, so enlarged lymph nodes are good candidates for excisional biopsies. These are less common now, since the development of fine needle aspiration (see below). Types of biopsyĪ whole organ or a whole lump is removed (excised). There is no qualitative difference between M.D.-pathologists and D.O.- pathologists, as both study in the same residency programs and take the same Board examinations. On successful completion of this exam, the pathologist is “Board-certified.” Almost all American pathologists practicing in JCAHO-accredited hospitals and in reputable commercial labs are either Board-certified or Board-eligible (a term that designates those who have recently completed residency but have not yet passed the exam). or D.O.) undertakes a five-year residency training program, after which he or she is eligible to take the examination given by the American Board of Pathology. To be a pathologist, a medical graduate (M.D. The pathologist is a physician specializing in rendering medical diagnoses by examination of tissues and fluids removed from the body. After the biopsy specimen is obtained by the doctor, it is sent for examination to another doctor, the anatomical pathologist, who prepares a written report with information designed to help the primary doctor manage the patient’s condition properly. ![]() This procedure is called a biopsy, a Greek-derived word that may be loosely translated as “view of the living.” Any organ in the body can be biopsied using a variety of techniques, some of which require major surgery (e.g., staging splenectomy for Hodgkin’s disease), while others do not even require local anesthesia (e.g., fine needle aspiration biopsy of thyroid, breast, lung, liver, etc). ![]() Many medical conditions, including all cases of cancer, must be diagnosed by removing a sample of tissue from the patient and sending it to a pathologist for examination.
