Definition

A demarcated, largely intraventricular tumor in the region of the foramen of Monro composed of spindle to large plump or ganglion-like cells with eosinophilic to amphophilic cytoplasm and somewhat pleomorphic nuclei with occasional prominent nucleoli. These tumors are almost always associated with tuberous sclerosis. [from HPO]

Disease or Syndrome
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 tubers, 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). Central nervous system tumors are the leading cause of morbidity and mortality; renal disease is the second leading cause of early death.
