Gaucher disease
Gaucher disease a lysosomal storage disease. It is a rare thingy seen in people that marry their cousins.
Pathology
- Accumulation of glucocerebroside in monocytes/macrophages due to deficiency of glucocerebrosidase.[1]
Subtypes
- There are several.
- All are autosomal recessive.[1]
Types:[2]
- 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."[4]
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:
