Parapharyngeal space tumors are uncommon, most are salivary gland tumors (50%), and they are often pleomorphic adenomas. Neurogenic tumors are the second most common primary tumors of all neoplasms in the parapharyngeal space (30%). Angiomyxolipoma is a very rare form of lipoma. Up until now, only 12 cases located on different sides of the body were reported. Presented here is a case report of a patient with an angiomyxolipoma of the parapharyngeal space. A 17-year-old boy had a slowly growing, painless mass on the left side of the neck. During the oropharyngeal examination, medial displacement of the left tonsilla palatina was observed. Magnetic resonance imaging findings were of a 6 × 5.5 × 3-cm "dumbbell"-shaped parapharyngeal mass. A fine needle aspiration of the mass showed no specific histopathology. The patient underwent a transparotid-transcervical approach for the excision of the tumoral mass under general anesthesia. Although an angiomyxolipoma is a rare form of lipoma, it is a pathology that should be kept in mind for the differential diagnosis of parapharyngeal tumors.
咽旁间隙肿瘤并不常见，大多数是涎腺肿瘤（50%），且多为多形性腺瘤。神经源性肿瘤是咽旁间隙所有肿瘤中第二常见的原发性肿瘤（30%）。血管平滑肌脂肪瘤是一种非常罕见的脂肪瘤类型。截至目前，仅报道了12例位于身体不同部位的病例。本文报告一例咽旁间隙血管平滑肌脂肪瘤患者。一名17岁男孩左侧颈部有一个生长缓慢、无痛性肿块。在口咽检查时，观察到左侧腭扁桃体向内侧移位。磁共振成像显示一个6×5.5×3厘米的“哑铃”形咽旁肿块。对该肿块进行细针穿刺抽吸，未发现特异性组织病理学结果。患者在全身麻醉下采用经腮腺-经颈入路切除肿瘤性肿块。尽管血管平滑肌脂肪瘤是一种罕见的脂肪瘤类型，但在咽旁肿瘤的鉴别诊断中应考虑到这种病理情况。
