Final answer:
Swelling from inflammation, trauma, or neoplasms is called edema, which is the accumulation of excess fluid in body tissues.
Step-by-step explanation:
The term used to refer to swelling from inflammation, trauma, neoplasms, and other similar causes is edema. Edema is an accumulation of excess fluid in the tissues which results in swelling. It is commonly seen in the soft tissues of the extremities. The physiological causes of edema include leakage of water from blood capillaries, often as a result of increased permeability of the capillary walls during an inflammatory response.
Edema is typically associated with underlying medical conditions, the use of certain drugs, pregnancy, injury, or allergic reactions. Symptoms include increased limb size, stretched skin, and pitting upon pressure. The inflammatory response to injury or infection can also lead to edema, as increased blood flow and the movement of leukocytes and fluid through capillaries to the site cause the tissue to swell.
