Fibrolipomas are benign lesions conformed by fat and connective tissue, classified as histologic variants of lipomas. They are rarely located in the head and neck and represent less than 0.6% of the benign tumors of the larynx and hypopharynx. Their clinical presentation depends on its location and size. We present the case of a 51-year-old male patient who reported progressive dyspnea, dysphagia and obstructive sleep symptoms with a duration of 3 months, without apparent cause. A pharyngolaryngeal fiberoptic endoscopy showed a smooth, rounded mass in the posterior wall of the hypopharynx, partially obstructing the laryngeal vestibule, creating a valve effect. Complete trans-cervical resection of the lesion was performed after the airway was secured by means of a tracheotomy. The final histopathology report was fibrolipoma. He is currently asymptomatic and without evidence of relapse one year after the procedure.
纤维脂肪瘤是由脂肪和结缔组织构成的良性病变，归类为脂肪瘤的组织学变体。它们很少位于头颈部，在喉和下咽的良性肿瘤中占比不到0.6%。其临床表现取决于其位置和大小。我们报告一例51岁男性患者，该患者出现进行性呼吸困难、吞咽困难和阻塞性睡眠症状，持续3个月，无明显病因。咽喉纤维内镜检查显示下咽后壁有一个光滑、圆形的肿块，部分阻塞喉前庭，产生瓣膜效应。在通过气管切开术确保气道安全后，对病变进行了完整的经颈切除。最终组织病理学报告为纤维脂肪瘤。术后一年，他目前无症状，且无复发迹象。
