Tuberous sclerosis (also called Tuberous sclerosis complex-TSC) is an inherited neurocutaneous and multisystemic disorder characterized by hamartomas (sclerotic tubers), which most notably affect the skin, brain, kidneys, heart and eyes. Tuberous sclerosis complex (TSC) is a genetic disorder affecting cellular differentiation, proliferation, and migration early in development, resulting in a variety of hamartomatous lesions that may affect virtually every organ system of the body. J Am Acad Dermatol 2001;45(3):450-2. SAN DIEGO – Everolimus reduces the frequency of epileptic seizures in patients with tuberous sclerosis complex (TSC), and its effect appears to gain strength over time.

Tuberous sclerosis is found in 50% of cases of rabdomyoma (in the other 50% of cases the cardiac tumor is an isolated finding). Changes include osteoporosis and cystic defects in the metacarpals, metatarsals and/or phalanges. By the end of an extension study, half of patients had at least a 31.7% reduction in seizure frequency at 18 weeks, and that percentage rose to 56.9% at 2 years. Tuberous Sclerosis Tuberous sclerosis (TS), also known as Bourneville disease, is an autosomal dominant neurocutaneous disorder, characterized by hamartomatous lesions in multiple organs and tissues. D ear E ditor , Tuberous sclerosis complex (TSC) is caused by pathogenic variants in TSC1 /TSC2, resulting in the formation of hamartomas in multiple organs. One half of the patients with tuberous sclerosis have musculoskeletal lesions. The clinical diagnosis of TSC is typically made during childhood, as most individuals develop epilepsy and have multiple clinical findings, including those involving the skin.
