This paper briefly summarizes current knowledge of Hodgkin's disease, based on a review of the voluminous recent literature and on the author's observations in 135 cases. Special features of the incidence patterns are noted. The initial clinical findings are described and problems of staging are discussed. Lymphangiographic techniques, as well as radioisotope scanning procedures which can now be used to study the liver, spleen, lung and bone marrow, have added new dimensions to the meaning of “clinically local disease.” The course of the disease is characterized by its great variability and the causes of death are multiple, with infection contributing in a major way. A general approach to therapy is outlined.
