The evidences of Hodgkin's disease in the bones as in spleen, liver, etc., are inconstant in appearance. The principal change is a progressive tissue formation (fibrous). Some new bone formed in one case. Coagulation necrosis, simple oedema and the presence of polymorphonuclear leucocytes indicate a more intense poisoning. The greater implication of the reticuloendothelial system, the presence of Dorothy Reed giant cells is more specifically a Hodgkin's disease involvement. There are more small round cells than seen in bone as a rule. Eosinophils are present in undue numbers. The bone matrix evidences oedema, bone cell activity and little necrosis. These are also erratic in location and severity. The vascular system is more involved than in common inflammation. Besides the hyperaemia, oedema and capillary hemorrhage with the breaking down of blood, there is seen thrombosis of the venous sinuses.
The polymorphonuclear leucocytes in the bone as in lymph glands of Hodgkin's disease are erratic in location and variable in numbers.
