What is the term for the condition characterized by fluid accumulation leading to swelling in the skin?

The term that describes the condition characterized by fluid accumulation leading to swelling in the skin is edema. Edema occurs when excess fluid builds up in the interstitial spaces of the tissue, causing noticeable swelling. This can occur in various parts of the body and can be a result of numerous factors including injury, inflammation, or certain medical conditions.

Hyperemia, while related to increased blood flow, does not specifically involve fluid accumulation in the way edema does. Youthfulness refers to the state of being young and does not pertain to any condition involving swelling. Infiltration typically refers to the penetration of a liquid or substance within tissue, but it does not specifically describe the accumulation of fluid that results in swelling like edema does. Understanding these distinctions is crucial for recognizing various skin conditions and their underlying causes.
