A case of solitary pulmonary nodule (large pulmonary chondroid hamartoma)

Abstract

Chondroid hamartomas are rare benign tumors of the lung which show predominantly cartilage. Usually, they are small, solitary, and asymptomatic lesions. They are detected incidentally on chest X-ray or at the time of autopsy. Occasionally, large pulmonary hamartomas are encountered. We present a case of a 60-year-old male patient with a 6-month history of cough. His X-ray and computed tomography (CT) scan of the chest revealed a well-defined soft-tissue density lesion with popcorn calcification measuring 6.5 cm × 4.8 cm in the left lung upper lobe. A presumptive diagnosis of chondroid hamartoma was made in CT-guided percutaneous biopsy. A posterolateral thoracotomy and left upper lobectomy were done. There was a spherical gray-white firm mass noted in the resected lobectomy specimen. Postoperative histopathological examination confirmed the diagnosis of pulmonary chondroid hamartoma. This is an additional case of large chondroid hamartoma.
