Gaucher disease is the most common lysosomal storage disease.[1] Despite being the most common in its grouping, it is still quite rare.
Like most storage disorders, it is inherited autosomal recessive; thus, it is seen more commonly in families where people are marry their cousins.
General
Pathology:
- Accumulation of glucocerebroside in monocytes/macrophages due to deficiency of glucocerebrosidase.[2]
- Defect in acid beta-glucosidase gene (GBA gene).[3][4][5]
Subtypes
- There are several types - all are autosomal recessive.[2]
Types:[6]
- Type I: 99% of cases; no CNS involvement - survive to adulthood.
- Type II: infantile onset - CNS degeneration + death at young age.
- Type III: mixed of type I & type II.
Clinical
- Pancytopenia - due to marrow replacement.
- Hepatosplenomegaly (type I).
Microscopic
- Mononuclear phagocytes with abundant eosinophilic cytoplasm with subtle irregular lines (~0.5 micrometers in width).
- Known as "crumpled tissue paper cells" / "crumpled tissue paper cytoplasm."[8]
Notes:
- Crumpled tissue paper: crumpled tissue paper - image (123rf.com).
- The textbook case may look crumpled... along with some mind altering drugs.
- The typical case is:
- Abundant macrophages with cytoplasm filled by very small (clear) vacuoles (~0.2-0.4 micrometres).
- The typical case is:
