Overview
Hamartomas may be classified into different types based on their location, such as lung (most common), heart, hypothalamus, kidneys, or spleen. Other classification method considers lesion class, dividing hamartomas into 4 different categories, such as bone-forming, cartilage-forming, fiber-forming, and benign non–matrix-forming.
Classification
Location
Based on the location, hamartomas can be classified into the following types:[1][2]
| Location | Type |
|---|---|
| CNS |
|
| Hypopharynx |
|
| Eyelid | |
| Lung |
|
| Heart | |
| Bowel | |
| Kidneys | |
| Spleen | |
| Skin |
|
Lesion class
Based on the lesion class, hamartomas may be classified into the following types:[3]
| Lesion class | Tumors type |
|---|---|
| Cartilage-forming | |
| Fiber-forming | |
| Bone-forming |
|
| Benign non-matrix-forming |
