Lipomas of the larynx, oropharynx and hypopharynx are rare, accounting for approximately 1% of benign laryngeal neoplasms. We present a rare case of a simple lipoma arising from the right vallecula. A 55-year-old male presented with worsening dysphagia for 1 week. CT scan revealed a lesion of fat attenuation in the right vallecula. The patient underwent surgical excision and recovered uneventfully. To our knowledge, there are only two cases of vallecular lipoma that have been reported and they are both of spindle cell subtype and located on the left side. This is the first reported case of a simple lipoma arising from the right vallecula and causing obstructive symptoms. CT scan or MRI is essential in confirming the diagnosis and assessing the extent, thus allowing prompt excision, especially when the patient is symptomatic.
喉、口咽和下咽的脂肪瘤很罕见,约占喉良性肿瘤的1%。我们报告一例罕见的起源于右侧会厌谷的单纯性脂肪瘤病例。一名55岁男性因吞咽困难加重1周就诊。CT扫描显示右侧会厌谷有脂肪密度的病变。患者接受了手术切除,恢复顺利。据我们所知,仅报道过两例会厌谷脂肪瘤病例,且均为梭形细胞亚型,位于左侧。这是首例报道的起源于右侧会厌谷并引起梗阻症状的单纯性脂肪瘤病例。CT扫描或MRI对于确诊和评估范围至关重要,从而能够及时进行切除,尤其是当患者出现症状时。
