What´s the difference, physiopathologically speaking, between enlargment and inflammation? Since hepatomegaly is not the same as hepatitis.

Inflammation vs. enl. Enlargement is just about an increase in size. It can be from abnormal tissue like cancer or infection or from excess growth of normal tissue. Inflammation is about the body's response to something abnormal like injury or infection. When inflammation occurs the body sends in cells to try and correct or mend the problem and this often results in swelling or enlargement.
