Benign intraluminar tumours of the hypopharynx or upper esophagus are often pedunculate. In cases of very soft tumours such as the present case (angiolipoma), the patient's symptoms may be so uncharacteristic that one might think of a "globus nervosus". If the peduncle is very thin, X-ray esophagograms or even endoscopic examinations may be negative. Those tumours may become very dangerous if, as a result of a vomiting reflex, they obstruct the upper airways. The present paper points out diagnostic problems. Diagnosis may be facilitated if anamnesis is considered carefully.
下咽或上食管的良性腔内肿瘤通常有蒂。在肿瘤非常柔软的情况下，如本例（血管脂肪瘤），患者的症状可能非常不典型，以至于可能会想到“癔球症”。如果蒂非常细，食管X线造影甚至内镜检查可能为阴性。如果这些肿瘤由于呕吐反射而阻塞上呼吸道，可能会变得非常危险。本文指出了诊断问题。如果仔细考虑病史，可能有助于诊断。
