Histologic and histochemical study of the foam cell in the spleen in thalassemia has shown that the foamy appearance is due to the accumulation of an
acidic mucopolysaccharide of the chondroitin sulfuric acid type in the cytoplasm of this histiocytic cell. This polysaccharide shows intense red coloration with the periodic acid Schiff reaction, which is thus of great value in
demonstrating the foam cell in tissue sections. The possible sources of this
mucopolysaccharide have been discussed.
