(+) foam cells from accumulation of sphingomyelin
Nieman-Pick
most common lysosomal storage disease
Gaucher disease
- MR (mental retardation)
- erosion of long bones

Gaucher disease
macophages that resemble
crumpled tissue paper
Gaucher disease
•called gaucher cells
- reddish purple skin rash
- kidney and HF
- X-linked recessive disease (full symptoms only in males)
Fabry
- sulfatides form granules that are metachromatic
* nerves stain yellowish-brown
