Tuberous sclerosis complex (TSC) involves abnormalities of the skin (hypomelanotic macules, confetti skin lesions, facial angiofibromas, shagreen patches, fibrous cephalic plaques, ungual fibromas); brain (subependymal nodules, cortical dysplasias, and subependymal giant cell astrocytomas [SEGAs], seizures, intellectual disability / developmental delay, psychiatric illness); kidney (angiomyolipomas, cysts, renal cell carcinomas); heart (rhabdomyomas, arrhythmias); and lungs (lymphangioleiomyomatosis [LAM], multifocal micronodular pneumonocyte hyperplasia). Tuberous sclerosis is the leading cause of this tumor. The incidenceis between 1/6,000 and 1/10,000. endobj Corpus ID: 56811387.

Evaluation of relatives at risk: Identifying affected relatives enables monitoring for early detection of problems associated with TSC, which leads to earlier treatment and better outcomes. Skin findings are present in nearly all patients with TSC, and major criteria in skin include facial angiofibromas, forehead plaque, nontraumatic ungual or periungual fibromas, three or more hypomelanotic macules, or a shagreen patch. -, Au KS, Williams AT, Roach ES, Batchelor L, Sparagana SP, Delgado MR, Wheless JW, Baumgartner JE, Roa BB, Wilson CM, Smith-Knuppel TK, Cheung MY, Whittemore VH, King TM, Northrup H.
