Hamartoma natural history

Prognosis
A hamartoma, while generally benign, can cause problems due to their location. When located on the skin, especially the face or neck, they can be extremely disfiguring, as in the case of a man with a hamartoma the size of a small orange on his eyelid. They may obstruct practically any organ in the body, such as the eye, the colon, etc. They are particularly likely to cause major health issues when located in the hypothalamus, spleen or kidneys.
