A 39-year-old man was admitted to our department with a 2-months history of foreign body sensation in the throat and aggravated 1 week. He complained of intermittent cough. No dyspnoea and dysphagia. Contrast-enhanced computed tomography revealed a strikingly enhancing tumor located the pharyngoesophageal junction with a mass protruding into the laryngeal vestibule. Images from transverse (Panel A), coronal (Panel B) and sagittal (Panel C) planes showed a bilateral hypopharynx and pharyngoesophageal junction enhancing mass. The tumor was extending outward through the cricothyroid space and indistinguishable from the right upper pole of the thyroid. A surgical resection of the tumor was planed. However, he suddenly coughed up a tumor mass with a small amount of bleeding and blood clot on the second night after hospitalization. The size of the coughed up tumor mass is 2cm×3cm×1cm (Panel D). The pathological result suggested that the coughed tumor is hemangiomatous polyp (Panel E). Considering the risk of massive bleeding, transarterial embolization was performed for the remaining polypoid lesion and the tumor located at the hypopharynx and pharyngoesophageal junction. The final pathological result of the surgical sample indicated that the tumor was renal clear cell carcinoma metastasis. The left renal mass was confirmed on US and CT after the diagnosis. Subramanyam et al.1 reported one similar case (Fig. 1).
