pulmonary hamartoma

What is a pulmonary hamartoma?

Pulmonary hamartoma is the most common benign neoplasm of the lung and typically manifests as an asymptomatic well-circumscribed SPN, during the fourth through seventh decades of life. Pathologically, these are mesenchymal tumors that have foci of mature cartilage separated by islands of fat and bronchial epithelium, often with fibrosis, calcification, or ossification. Typical CT findings include a smoothly marginated SPN that often contains visible fat or dense foci of calcification or ossification or both.
