Wikipedia on Gross pathology

Gross pathology refers to macroscopic manifestations of disease in organs, tissues, and body cavities. The term is commonly used by anatomical pathologists to refer to diagnostically useful findings made during the gross examination portion of surgical specimen processing or an autopsy. More »

Atrophy
Atrophy is the partial or complete wasting away of a part of the body. Causes of atrophy include poor nourishment, poor circulation, loss of hormonal support, loss of nerve supply to the target organ, disuse or lack of exercise or disease intrinsic to the tissue itself. Hormonal and nerve inputs that maintain an organ or body part are referred to as ''trophic''. Atrophy is a general physiological process of reabsorption and breakdown of tissues, involving apoptosis on a cellular level. More »
Muscle atrophy
Muscle atrophy refers to a decrease in the size of skeletal muscle, which occurs in a variety of settings. Atrophy may or may not be distinct from "sarcopenia", which is the loss of muscle seen in the aged. When a muscle atrophies, it necessarily becomes weaker, since the ability to exert force is related to mass. More »
Stenosis
A stenosis is an abnormal narrowing in a blood vessel or other tubular organ or structure. It is also sometimes called a "stricture" . Stenoses of the vascular type are often associated with a noise resulting from turbulent flow over the narrowed blood vessel. This bruit can be made audible by a stethoscope. Other, more reliable methods of diagnosing a stenosis are imaging methods including ultrasound, Magnetic Resonance Imaging/Magnetic Resonance Angiography, Computed... More »
Adenoid hypertrophy
Adenoid hypertrophy is the unusual growth of the adenoid tonsil. There is very little lymphoid tissue in the nasopharynx of young babies; humans are born without substantial adenoids. The mat of lymphoid tissue called adenoids starts to get sizable during the first year of life. Just how big the adenoids become is quite variable between individual children. Enlarged adenoids can become nearly the size of a ping pong ball and completely block airflow through the nasal passages. More »
Aneurysm
An aneurysm is localized, blood-filled dilation of a blood vessel caused by disease or weakening of the vessel wall. Aneurysms most commonly occur in arteries at the base of the brain and in the aorta , a so-called aortic aneurysm. The bulge in a blood vessel can burst and lead to death at any time, much like a bulge in an over-inflated innertube. The larger an aneurysm becomes, the more likely it is to burst. Aneurysms can be treated. More »
Cerebral atrophy
Cerebral atrophy is a common feature of many of the diseases that affect the brain. Atrophy of any tissue means loss of cells. In brain tissue, atrophy describes a loss of neurons and the connections between them. Atrophy can be generalized, which means that all of the brain has shrunk; or it can be focal, affecting only a limited area of the brain and resulting in a decrease of the functions that area of the brain controls. If the cerebral hemispheres are affected, conscious thought and... More »
Arteriovenous malformation
Arteriovenous malformation or AVM is a congenital disorder of the connections between veins and arteries in the vascular system. The genetic transmission patterns of AVM are unknown, and AVM is not generally thought to be an inherited disorder--unless in the context of a specific hereditary syndrome. Arteries and veins are part of the human cardiovascular system. Normally, the arteries in the vascular system carry oxygen-rich blood at a relatively high pressure. More »
