pulmonary chondroma

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

Epidemiology

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

Pathology

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 .

Macroscopic appearance

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

Differential diagnosis

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