For the most part, a pathologist's work consists of other than tumor samples. Inflammatory and degenerative diseases are classified according to etiology and character into groups differing significantly in their treatment and prognosis. In these diseases, histopathologic analysis continues to be one of the most important tools for their classification and assessment of the degree of severity. Even a negative finding assists in directing further investigations and follow-up. The development of new analysis methods along with new marker substances has helped to find even novel disease groups such as IgG4-associated inflammatory diseases.
