History

Readily visible alterations of the skin surface have been recognized since the dawn of history, with some being treated, and some not. In 1801 the first great school of dermatology became a reality at the famous Hôpital Saint-Louis in Paris, while the first textbooks (Willan's, 1798–1808) and atlases (Alibert's, 1806–1814) appeared in print during the same period of time. In 1952, Dermatology was greatly advanced by Dr. Norman Orentreich's pioneering work in hair transplantation.

Training

After earning a medical degree (M.D. or D.O.), the length of training for a general dermatologist in the United States is a total of four years. This training consists of an initial medical or surgical intern year followed by a three-year dermatology residency. Following this training, one- or two- year post-residency fellowships are available in immunodermatology, phototherapy, laser medicine, Mohs micrographic surgery, cosmetic surgery or dermatopathology. Within the past several years, dermatology residencies in the United States have been the most competitive in terms of admission

American College of Surgeons

Members of the American College of Surgeons are referred to as "Fellows." The letters FACS (Fellow, American College of Surgeons) after a surgeon's name mean that the surgeon's education and training, professional qualifications, surgical competence, and ethical conduct have passed a rigorous evaluation, and have been found to be consistent with the high standards established and demanded by the College.

The American College of Surgeons also has membership categories for Associate Fellows (provides an opportunity for surgeons who are beginning surgical practice and who meet specific requirements to assume an active role in the College at an early stage in their careers), surgical residents, medical students, and allied health care professionals who are not surgeons, but who interact with surgical patients.

As of 2008, total membership was over 75,000 including more than 4,000 members from outside the US and Canada, and more than 2,600 Associate Fellows. Fellows of the College are organized into 100 chapters. There are 65 chapters in the United States, 2 in Canada, 3 in Mexico, and 30 in other countries around the world.

The ACS elected its first black Fellow, Dr Louis T. Wright, in 1934.

Core Needle Biopsy

A core needle biopsy is a procedure that removes small but solid samples of tissue using a hollow "core" needle. For palpable (“able to be felt”) lesions, the physician fixes the lesion with one hand and performs a freehand needle biopsy with the other. In case of non-palpable lesions stereotactic mammography, or ultrasound, or PEM guidance is used. With stereotactic mammography it is possible to pinpoint the exact location of a mass based on images taken from two different angles of the x-ray machine. With ultrasound, the radiologist or surgeon can watch the needle on the ultrasound monitor to help guide it to the area of concern. With PEM (positron emission mammagraphy), the lesion is targeted in 3D based on a positron emission tomography (PET) image of the breast. The needle used during core needle biopsy is larger than the needle used with FNA. The core biopsy needle also has a special cutting edge allowing removal of a bigger sample of tissue. With Core Needle Biopsy a relatively large sample can be removed through a small single incision in the skin. Typically, the breast area is first locally anesthetized with a small amount of anesthetic fluid. Then, the needle is placed into the breast. As with FNA, the radiologist or surgeon will guide the needle into the area of concern by palpating the lump. If the lesion can’t be felt the core needle biopsy is performed under image-guidance using either stereotactic mammography, ultrasound or even magnetic resonance imaging (MRI). A core needle biopsy procedure takes a few minutes to perform and is almost painless.

Biopsy

A biopsy is a medical test involving the removal of cells or tissues for examination. It is the removal of tissue from a living subject to determine the presence or extent of a disease. The tissue is generally examined under a microscope by a pathologist, and can also be analyzed chemically. When an entire lump or suspicious area is removed, the procedure is called an excisional biopsy. When only a sample of tissue is removed with preservation of the histological architecture of the tissue’s cells, the procedure is called an incisional biopsy or core biopsy. When a sample of tissue or fluid is removed with a needle in such a way that cells are removed without preserving the histological architecture of the tissue cells, the procedure is called a needle aspiration biopsy.
