Tuberous sclerosis complex (TSC) is a rare multisystem autosomal dominant genetic disease that causes non-cancerous tumours to grow in the brain and on other vital organs such as the kidneys, heart, liver, eyes, lungs and skin.
Adenoma sebaceum presence represents one of the major diagnostic criteria to confirm the diagnosis of tuberous sclerosis. [5] When adenoma sebaceum presents with seizures and mental retardation (Vogt's triad), it indicates that cranial imaging is necessary, other differential diagnoses for this disorder include acne vulgaris, rhinophyma, and sebaceous hyperplasia.
Tuberous Sclerosis Complex (TSC): TSC is a genetic condition that leads to the formation of benign tumors in multiple organs. Dermatological signs such as hypomelanotic macules and facial angiofibromas are common, and poliosis can occasionally be an early indicator of TSC.
A case of tuberous sclerosis showing facial angiofibromas in characteristic butterfly pattern. Herbert L. Fred, MD and Hendrik A. van Dijk Symptoms and signs of tuberous sclerosis Tuberous sclerosis complex (TSC) is a multisystemic disorder due to autosomal dominant mutations in either TSC1 or TSC2 which results in the impaired inhibition of ...
Typically, it presents in children aged 3–5 years and most of the time persists into adulthood with slight changes in the electroclinical phenotype. [2] [3] It has been associated with perinatal injuries, congenital infections, brain malformations, brain tumors, genetic disorders such as tuberous sclerosis and numerous gene mutations.
It has an association with tuberous sclerosis. [1] In those with tuberous sclerosis, the tumor may regress and disappear completely, or remain consistent in size. [ 2 ] A common histological feature is the presence of spider cells, which are cardiac myocytes with enlarged glycogen vacuoles separated by eosinophilic strands, resembling the legs ...
Although the prevalence of tuberous sclerosis at 1 in 6,000 births is much greater than that of LAM, most pulmonary clinics see more cases of sporadic than tuberous sclerosis–LAM: probably due to a combination of low levels of screening for LAM in tuberous sclerosis and in many, the absence of symptoms.

The skin lesions caused by tuberous sclerosis (angiofibromas) must be distinguished from the characteristic fibrofolliculomas of BHD, which also occur primarily on the face. BHD can be difficult to diagnose from symptoms alone, because hereditary renal cancers, pneumothorax, and cutaneous tumors occur with other syndromes.
