Massive chondroid hamartoma of the lung clinically masquerading as bronchogenic carcinoma

Chondroid hamartomas of the lung are uncommon lesions which are generally small sized and asymptomatic. Herein we describe a case of a large-sized pulmonary chondroid hamartoma which clinically mimicked bronchogenic carcinoma. A large hilar growth was detected in the left lung on radiological studies. Left upper lobectomy was done. The growth was well defined with a lobulated bluish cut surface. Histopathology disclosed lobules of mature cartilage rimmed by long slit-like epithelial channels admixed with mature adipose tissue.
