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:[1][2]

  • Neuroepithelial cells in tuberous sclerosis
Hypopharynx
  • Hypopharyngeal rhabdomyomatous
Eyelid
  • Rhabdomyomatous mesenchymal hamartoma
Lung
  • Endobronchial pulmonary hamartoma
  • Parenchymal pulmonary hamartoma
  • Bronchial hamartoma
Heart

Bowel
  • Peutz-Jeghers polyp
  • Polyp of the large bowel
Kidneys
  • Angiomyolipoma
Spleen

Lesion class

Based on the lesion class, hamartomas can be classified into the following types:[3]

Lesion class Tumors type
