A 64-year-old man underwent endoscopic diagnosis of ahypopharyngeal lesion of the pyriform sinus after the onsetof dysphonia and dysphagia. Based on the histology ﬁnd-ings, a ﬁnal diagnosis of small cell neuroendocrine carcinoma(SCNEC) of the pyriform sinus was performed (Fig. 1) and thepatient underwent ﬂuorine-18-ﬂuorodeoxyglucose positron emis-sion tomography/computed tomography (
