Tuberous Sclerosis synonyms

Tuberous Sclerosis Complex (TSC) is the current official medical term for this multisystem genetic disorder, historically referred to as Epiloia or Bourneville’s disease. While you may encounter various legacy names in older medical literature or international records, healthcare providers now standardize on "Tuberous Sclerosis Complex" to reflect the condition's systemic, multi-organ nature.

Why does Tuberous Sclerosis have so many names?

The naming of Tuberous Sclerosis has evolved alongside our clinical understanding of the disease. Historically, the condition was named after the physicians who first described its clinical features, such as Désiré-Magloire Bourneville, who coined the term "tuberous sclerosis of the cerebral convolutions" in 1880. Another common historical term, "Epiloia," was introduced in 1908 by Epiloia (an acronym for Epilepsy, low intelligence, and adenoma sebaceum). As medical research progressed and we realized that not all patients exhibit every symptom of this triad, the term "Complex" was added to Tuberous Sclerosis to emphasize that the disease affects multiple organ systems, not just the brain and skin.

What are the historical and alternative names for Tuberous Sclerosis?

When reviewing older medical files or international research, you may find the condition referred to by several synonyms. It is important to recognize these labels, as they all point to the same underlying genetic mutations in the TSC1 or TSC2 genes. Common alternative names include:

• Bourneville’s disease: Named after the French neurologist who provided the first detailed pathological description.


• Epiloia: An archaic term that is no longer used in modern clinical practice due to its stigmatizing roots.


• Tuberous Sclerosis Complex (TSC): The currently preferred term used by the NIH, Orphanet, and international medical boards.


• Pringle’s disease: Sometimes used to refer specifically to the facial skin manifestations (angiofibromas) associated with the condition.

How is Tuberous Sclerosis classified in medical systems?

Standardized medical classification systems are essential for accurate diagnosis and billing. In the International Classification of Diseases (ICD-10 and ICD-11), the condition is formally coded under Tuberous Sclerosis. The Online Mendelian Inheritance in Man (OMIM) database, which catalogs human genes and genetic disorders, classifies the condition under two distinct entries: #191100 for TSC1 and #613254 for TSC2. Orphanet, the reference portal for rare diseases, uses the umbrella term Tuberous Sclerosis Complex to ensure that patients and researchers worldwide can access consistent, evidence-based data.

Why do medical professionals prefer the term Tuberous Sclerosis Complex?

The transition to using "Complex" is intentional. The 351 members of the DiseaseMaps.org community living with Tuberous Sclerosis understand that the disease is a spectrum. By using the term Tuberous Sclerosis Complex, clinicians highlight that the condition is a systemic disorder that can involve the kidneys, lungs, heart, and eyes, in addition to the brain and skin. This terminology helps shift the clinical focus from a narrow, symptom-based diagnosis to a comprehensive, multidisciplinary management approach.

Next steps

• Consult a geneticist to confirm your specific TSC1 or TSC2 mutation if you have not already done so.


• Request that your medical records be updated to reflect the current standard terminology: Tuberous Sclerosis Complex.


• Connect with the 351 community members on DiseaseMaps.org to share experiences and navigate the complexities of this diagnosis.


• Schedule regular screenings with a neurologist and nephrologist, as recommended by the International Tuberous Sclerosis Complex Consensus Group.
