A loose, mucous tumor called edema

It is a white, flabby tumor that has no heat; the thinner and wetter the material, the greater the looseness and the easier the finger goes deeper when pressed, although some resistance is still felt, which is not present with wind swelling. And the thicker the matter, the harder and colder this tumor is.

Many such tumors are formed from steam generated by mucus, and then they belong to the category of edema. Edema differs from black gall tumor in its low hardness and slight dark color; if it arises from a blow or something similar, it finds no matter except mucus to attract it to the bruised place, so that only a mucous swelling is formed. Such a tumor is rare and does not occur without pain.
