LipedemaFluid and fat are two different types of fluids, and the terminology is separated accordingly. Accumulation of fluids depends on what type of fluid is: it's water, it can be a hydrocele, or it can be edema. This depends on the distribution of the water. Accumulation of fat is termed also according to distribution. If the fat is all in one area, it can be termed as an adipoma or lipoma, depending on how soft the accumulation is. Adipoma can be one large bump containing fat. Lipoma is usually a harder, more tumorous accumulation of fat, usually on the surface of the skin.
