A hamartoma is an abnormal growth that's made up of the same tissue from which it grows.
- The abnormality is that there are an excess number of cells that are structurally different from the main cells.
- A hamartoma occurs when the tissue in the growth did not develop completely.
- Hamartomas can occur throughout the body, but are often found in the head and neck, particularly around the ears.
- If hamartomas occur in multiple sites throughout the body, their presence is called Cowden's disease.
Hypothalamic hamartomas and epilepsy
A hamartoma in the hypothalamus can cause your child to have seizures. Recent studies have shown that using a minimally invasive endoscopic operation to remove this kind of hamartoma has been incredibly effective. Take a look at Boston Children's Hospital's Center for Robotic and Minimally Invasive Reconstructive Surgery for more information.
