Polypoid tumors of the esophagus present diagnostic and therapeutic problems. Liposarcomas are infrequent among them. We report a recent case. A 73-year-old male patient was seen in May 1995 in the Ear, Nose and Throat (ENT) Department, Clínica Modelo de Morón, with intermittent dysphagia and dyspnoea due to recurrent vomiting. A laryngeal lineal tomography showed a subglottic obstruction due to extrinsic compression. The patient was referred to the Gastroenterology Department, where an upper gastrointestinal (upper GI) series demonstrated mega-esophagus with abundant retained food. Endoscopy showed a large intraluminal mass covered by normal mucosa which arose on the posterior wall. Videofluoroscopy and chest CT diagnosed a probable polypoid lipoma due to its densitometric characteristics. The tumour was resected by left cervicotomy and left esophagotomy. The patient's progress to date is favourable. Pathology studies showed a well-differentiated liposarcoma. According to the literature, the first case was reported in 1983, and ours is only the seventh case in the world to be documented.
食管息肉样肿瘤存在诊断和治疗方面的问题。其中脂肪肉瘤较为罕见。我们报告近期的一例病例。一名73岁男性患者于1995年5月就诊于莫龙模范诊所耳鼻喉科，因反复呕吐出现间歇性吞咽困难和呼吸困难。喉部线性断层扫描显示声门下梗阻是由外部压迫所致。该患者被转诊至胃肠病科，上消化道造影显示食管扩张并有大量潴留食物。内镜检查显示一个大的腔内肿物，被正常黏膜覆盖，起源于后壁。视频透视和胸部CT因其密度测量特征诊断为可能的息肉样脂肪瘤。通过左颈切开术和左食管切开术切除肿瘤。患者至今恢复良好。病理研究显示为高分化脂肪肉瘤。据文献记载，首例病例于1983年报告，我们的病例是世界上有记录的第七例。
