The difference between them is recognized by position, shape and characteristics. Regarding the position, the difference is determined by the fact that a tumor in the muscles is always obvious, while a tumor in the liver is sometimes not obvious, especially in the cavity and in obese people, unless, of course, the case is not terrible. The muscle tumor is located either transversely, or along, or obliquely and runs along the muscle; we have already pointed this out in anatomy. In terms of shape, the difference is determined by the fact that the obvious part of the tumor in the liver is semilunar, in accordance with the position of the liver, and its outline is felt along the border of the abdominal walls common with the liver, while the muscular tumor is oblong and one end is thick and the other thin, and looks like a mouse's tail. Therefore, the muscle tumor is not felt along the common border with the abdominal walls, and you, on the contrary, observe that it gradually becomes thinner in the longitudinal direction; often you can feel only a part of it that lies deep and oblong if it is located in muscles located deep and obliquely; such a tumor is more similar to tumors in the liver. As for recognition by signs, with muscle tumors the special and general signs inherent in tumors located in the liver are not observed to any significant extent. If you see that the abdominal walls are quickly thinning and dry, consider that the tumor is liver.
