Overview

Hamartomas may be classified into different types based on their location, such as: lung (most common), heart, hypothalamus, kidneys, or spleen. Other classifications can consider 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:

Location	Type
Hypothalamus and tuber cinereum	Hypothalamic hamartoma
CNS	Neurofibromatosis in von Recklinghausen disease Neuroepithelial cells in tuberous sclerosis
Lung	Endobronchial pulmonary hamartoma Parenchymal pulmonary hamartoma Bronchial hamartoma
Heart	Rhabdomyoma
Kidneys	Angiomyolipoma
Spleen	Splenic hamartoma
Skin	Melanocytic nevi
