Representative image of HE stain (a): Dense infiltrate of Langerhans-type histiocytes and eosinophilic cells with many red blood cells (× 200). (b): A large amount of hemosiderin and macrophages which contained hemosiderin(× 400). (c): A large amount of necrotic tissue within the tumor cells(× 200); (d): A large proliferation of Langerhans cells, eosinophils and neutrophils as well as lymphocytes with scattered plasma cells and blood cells(× 400)
