Pulmonary chondroma

Dr Henry Knipe et al.

Pulmonary chondromas are rare, benign cartilaginous tumours of the lungs, and form part of the Carney triad although they can also arise sporadically.

Sporadic pulmonary chondromas occur most frequently in middle-aged males, while those associated with Carney triad occur most frequently in young females 3.

Pulmonary chondromas consist entirely of calcified/ossified cartilaginous components. This differentiates them from pulmonary hamartomas, which also contain fat, smooth muscle, epithelial and stromal elements. They can arise in the lungs, bronchi, trachea, and larynx 1,2

Well-circumscribed mass with a gray-white cartilaginous appearance 3.

On imaging consider the differential diagnosis for a calcified lung nodule.
