Primary percutaneous coronary intervention was performed, and a long, string-shaped contrast defect was observed in the left anterior descending artery (Fig. 1A). Optical coherence tomography (OCT) imaging revealed an odd, smooth-surfaced 50-mm long object (Fig. 1B). A long, white object which looked like a parasitic worm was retrieved via intracoronary aspiration and revascularization was successfully completed since neither plaque rupture or the presence of thrombus was detected by OCT (Fig. 1C). Contrast computed tomography revealed a huge 7x6 cm mass that was recognized at admission in the right upper pulmonary lobe with direct pulmonary vein invasion (Fig. 1D).
Histopathologic examination of the aspirated coronary object revealed pleomorphic lung carcinoma. Immunohistochemically, tumor cells were positive for both cytokeratin and vimentin.

Although the bronchoscopic findings were negative for a lung tumor, a histopathologic examination of the aspirated coronary object revealed pleomorphic lung carcinoma (Fig. 2).

He responded to the treatment and showed a good clinical course afterwards (Fig. 3).
