Successful removal of a giant pulmonary hamartoma coexisting with an anomalous common pulmonary venous trunk.
We present an extremely rare case of a giant pulmonary hamartoma (PH) coexisting with an anomalous common pulmonary venous trunk (ACPVT). An asymptomatic 39-year-old man was referred for evaluation of a giant pulmonary lesion in his left thorax detected on chest X-ray during a routine medical examination. After clinical work-up, the patient underwent left exploratory thoracotomy. Since the extent of the tumor and coexistence of an ACPVT, a left pneumonectomy was performed. The specimen measured 28 cm × 18 cm × 17 cm and weighted for 2.1 kg. Histology revealed a blend of pieces of rounded cartilage separated by fibrous bands in which mature adipose tissue and cleft-like structures lined. The features were consistent with those of a chondromatous hamartoma. The patient made a satisfactory recovery and 10 months after the operation was asymptomatic.
