Tuberous sclerosis, also tuberous sclerosis complex (abbreviated TSC), is an autosomal dominant syndrome associated with an increased risk of hamartomas.
Historically described as:[1]
- Epilepsy.
- Mental retardation.
- Adenoma sebaceum (angiofibromas).
General
Associations
Pathologic:
- Renal angiomyolipoma.
- Seen in 80% of individuals with TSC.[2]
- Cardiac rhabdomyoma.
- Lymphangiomyomatosis.
- Subependymal giant cell astrocytoma (SEGA).[3]
- Renal cysts.[2]
- Tuberous sclerosis-associated renal cell carcinoma - an evolving entity.[2]
Note:
- The same genes (TSC1, TSC2) are implicated in PEComas.
Mnemonic SALSA HEART:[4]
- Shagreen patches.
- Shagreen patch = connective-tissue nevus composed of collagen, i.e. collagenoma.[5]
- Ash Leaf spots.
- SEGA.
- Angiofibroma.
- Hamartomas.
- Epilepsy.
- Angiomyolipoma.
- Rhabdomyoma.
- Tubers.
Genes
- TSC1.[6]
- TSC2[7] - some evidence to suggest it is more often implicated in malignant tumours than TSC1.[8]
Incidence
~1 in 10,000 population.[1]
