Increased amounts of sphingolipids are found in lungs, liver, spleen, brain, and most other organs of the body. These organs are filled with large, pale, foamy cells which stain positively with lipid stains. About 150 cases have now been reported in clinical, pathological, and, rarely, in chemical studies.
