RESECTION OF AN UNSUSPECTED PRIMARY PULMONARY CHORIOCARCINOMA

Primary pulmonary choriocarcinoma is an exceedingly rare clinical enti ty in men. In this report, we present a man with an asymptomatic pulmo nary mass, which was diagnosed as non-small cell lung cancer by the us e of percutaneous transthoracic needle biopsy, who underwent left uppe r lobectomy. Final pathologic examination proved this tumor to be prim ary choriocarcinoma of the lung. We conclude that surgical resection o f incidental primary pulmonary choriocarcinoma, an extremely fatal mal ignancy, may be an appropriate treatment of choice.
